What to do with the existing spatial data in planning
The document discusses harmonizing spatial planning data from different regions in Europe to be compliant with INSPIRE directives. It describes the Plan4all project which developed conceptual data models for several INSPIRE themes including land cover, land use, and natural risk zones. The harmonization process involves describing source data, defining transformations between source and target structures, and publishing the harmonized data through web services and applications. Lessons learned include clearly defining source data and code lists to aid transformation and addressing differences in how terms are used across countries.
Road traffic modelling
Austria's traffic model is used by national and state authorities to plan infrastructure projects. It forecasts road and rail traffic volumes based on demographic and economic data. The iMOVE project aims to improve the model by combining different cargo movement surveys, incorporating toll data, and calibrating origin-destination flows using traffic counts. This will produce a more accurate and repeatable process for compiling cargo movement data on Austria's road network.

WHITE PAPER: Data Harmonization & Interoperability in OpenTransportNet
OpenTransportNet (OTN) distributes a series of White Papers to showcase its innovative approach in the
technical implementation of the OTN Hubs, and to communicate key outcomes in terms of service creation
and harmonisation of transport related data.
The White Papers are intended to provide insights and share lessons learned to others interested in using
the OTN approach for aggregating, harmonizing and visualising transport data. The audience for these
White Papers are mainly city and regional authorities that maintain and aggregate diverse data sources and
stimulate innovation development in transport, and the wider community of developers and experts in the
field of (geo) data as an opportunity to network and exchange knowledge.
This first White Paper, in a series of three, focuses on the data harmonisation process of the OTN project,
and is structured along the following use cases: (1) metadata harmonization through the CKAN and Micka
metadata management tools, and the upcoming GeoDCAT-AP metadata profile, (2), the DataTank data
management system and (3) the harmonized data model for road network data.
The paper starts with the main concepts of data interoperability and harmonization. Next, the use cases
are described that were implemented in the OTN project until January 2016 with the collaboration of the
four pilot cities (Antwerp, Issy-les-Moulineaux, Birmingham and the Liberec Region) and with the
consultation of the standard bodies Open Geospatial Consortium (OGC) and the World Wide Web
Consortium (W3C), and the in-house research centre of the European Commission, the Joint Research
Centre (JRC). The White Paper ends with harmonization guidelines for cities and regions interested in using
the OTN approach, and next steps of the OTN project in harmonization.
The second White Paper will describe further transport-related use cases including the Smart Points of
Interest in RDF and the Open Land Use Map. The second paper will also elaborate on the licensing aspects
of the project. The last White Paper will provide testimonials of pilot cities and regions and their key
outcomes, including innovative ways of big data visualizations and the involvement of local communities in
the co-creation of services.

Qing TRB Poster 16
This paper presents a new Hierarchical Clustering and Grid Mapping (H-G) approach to estimate hourly traffic emissions for an entire city using cellular activity data. The proposed method involves five steps: 1) preprocessing cellular data to generate GPS-labeled records, 2) generating a grid map of the city, 3) using hierarchical clustering to group cell towers and generate centroids, 4) matching movements to grids using shortest path algorithms, and 5) estimating emissions using an output of vehicle miles traveled in each grid. The method was tested using data from a midsize city in China and was able to reveal city-scale traffic dynamics and estimate hourly vehicle emissions across the entire city.

Understanding Map Integration Using GIS Software_ff
This document discusses map integration methods for road network data from two sources, the Virginia Department of Transportation's Linear Referencing System (LRS) and proprietary data from INRIX (XD). Two methods, spatial join and transfer attributes, are evaluated on five Virginia interstates. Spatial join joins features based on intersecting geometry, while transfer attributes joins on common attributes within a search distance. The accuracy of each method is calculated based on the number of features that match between the datasets. Spatial join is tested using different coordinate systems and LRS layers, while transfer attributes varies the search distance. Visualizing the buffers helps understand how distance affects matching.

TRB 2014 - Automatic Spatial-temporal Identification of Points of Interest in...
Presented at the Transportation Research Board 2014 meeting - Past research in travel surveys has shown that a GPS mobile phone-based survey is a useful tool for collecting information about individuals. While a passive travel survey collection is preferred to an active travel survey method, passive collection remains a challenge due to a lack of high accuracy algorithms to automatically identify trip starts and trip ends. This paper presents Automatic Spatial Temporal Identi cation of Points of Interest (ASTIPI), an unsupervised spatial temporal algorithm to identify POIs. ASTIPI utilizes the temporal and spatial properties of the dataset to obtain a high accuracy of POI identi cation, even on a reduced GPS dataset that uses techniques to conserve battery life on mobile devices. While reducing outliers within POIs, ASTIPI also has a linear running time and maintains the temporal orders of the location data so that arrival and departure information can be easily extracted and thus, users' trips can be quickly identi ed. Using real data from mobile devices,evaluations of ASTIPI and other existing algorithms are performed, showing that ASTIPI obtains the highest accuracy of POI identi cation with an average accuracy of 88% when performing on full datasets generated using the GPS Auto-Sleep module and an average accuracy of 59% when performing on reduced datasets generated using both the GPS Auto-Sleep module and the Critical Points algorithm.

Preliminary survey results from over 200 riders found that most users felt more satisfied with transit service and relaxed when waiting since using OneBusAway.
USF Project - Enhancing Transportation Safety & Security via Scalable Locatio...
This project developed a prototype system that can serve as a modern high-tech “Neighborhood Watch” enabling law enforcement officials access to the many “eyes and ears” of the public. Cell phones with embedded digital cameras allow the instant capture and remote submission of suspicious circumstances through pictures or video to authorities that may warrant further attention or action by law enforcement. Not only does this give the responding party a visual representation of the situation, but other information such as time, date, voice recordings, and physical location of the reporting party in Global Positioning System (GPS) coordinates can also be automatically attached to the report. Upon submission, the picture or video and other information is automatically processed and displayed on a map-based web page to give the dispatcher a real-time “birds-eye” view of incoming alerts. The system intelligently filters and organizes submissions so they can be efficiently managed, therefore allowing the dispatcher to handle many more submissions simultaneously identifying trends and patterns that may not be immediately obvious to a human observer.
Screenshot of WiVia website showing ability to send multimedia messages to phones based on their location
Another aspect of the system is its “reverse 911” component for data-enabled mobile phones. When a threat to the public or individuals is identified, the dispatcher could instantly relay a message to individuals with cell phones or PDAs in a certain geographic area. Examples of such information could be the need to evacuate a particular area (e.g., hurricane) where the real-time control of when, where, and to whom such information is disseminated. Another example is distributing an Amber Alert photo of a missing child to the geographic area where the child was last seen. The project team has successfully implemented a prototype application that runs on a cell phone, reports the position of the phone to the server, and then, based on calculations against a Hillsborough County map, returns a text message to the phone with information on the hurricane evacuation zone that the individual is currently located in (i.e “You are in Evacuation Zone C, which is currently under a mandatory evacuation order”).

My Ph.D. dissertation defense! :)
With the number of Global Positioning System (GPS)-enabled mobile phones rapidly increasing due to maturing positioning technologies, intelligent location-aware applications are poised to become the next innovation in mobile phones. However, innovations bring new challenges. As cellular data networks achieve broadband speeds, constrained device resources (e.g. battery life) replace bandwidth as a primary limiting factor for mobile applications. IP-based networking protocols, now widely available in Java Micro Edition devices, must be carefully integrated into existing architectures to meet application needs and maximize system efficiency. Evolving location-aware architectures require intelligent clients for low-latency real-time applications and efficient management of device resources, as well as server-side intelligence to analyze past user behavior. This paper expands previous work on location-aware architectures and presents Location-Aware Information Systems Client (LAISYC), a comprehensive location-aware framework supporting intelligent real-time mobile applications.

The many-uses-of-gtfs-data-–-its-america-submission-abbreviated
The General Transit Feed Specification, or GTFS, has become the most popular world-wide data
format to describe fixed-route transit services. Many transit agencies have created and published
GTFS data with the primary purpose being integration with Google Maps. However, GTFS data
can power many other different types of transit and multimodal software applications, including
multimodal trip planning, timetable creation, mobile apps, visualization, accessibility, analysis
tools for planning, real-time information, and interactive voice response (IVR). This paper
provides an overview of the many opportunities available for transit and intermodal agencies to
leverage open GTFS data and provide many new types of information services to the public or
their internal operations with little to no cost to the agency. For transit agencies without open
data, this paper will inform decisions on prioritizing and justifying investments in open data
initiatives. For agencies that already provide open access to GTFS data, this paper will assist the
agency in maximizing their investment in GTFS data by providing resources on how to access
many new types of applications. Departments of Transportation, Metropolitan Planning
Organizations, and other intermodal agencies will also benefit from this paper by learning the
state of the art in transit information dissemination, which can power new state-of-the-art
intermodal applications. This paper also provides a summary of industry best-practices that an agency can follow when deciding to create and share an open GTFS data feed to maximize exposure to new applications.
OpenDataWeek Marseille 2013 : Andrew Byrd -- The General Transit Feed Specifi...
The General Transit Feed Specification (GTFS) is an open specification for public transportation schedules and associated geographic information that allows for easy exchange of transit data between different systems. It originated in 2005 when TriMet in Portland, Oregon published their transit data in simple text file format for use in Google trip planning tools. GTFS has since been widely adopted for transit data sharing in the United States and parts of Europe due to its simplicity compared to larger XML specifications. The GTFS format continues to evolve through a collaborative review process to add only backward-compatible improvements that address real use cases.

Federal legislation requires transportation organizations to consider land use impacts of transportation plans. Researchers examined different land use modeling methods and applied several to the Waco, Texas region. They developed a new open-source gravity-based land use model called G-LUM and compared it to other models using Waco and Austin data under various scenarios. Researchers concluded most transportation organizations could benefit from straightforward land use tools, as existing models have documentation and usability issues.

Delivering Application-Layer Traffic Optimization (ALTO) Services based on ...Danny Alex Lachos Perez
Application-Layer Traffic Optimization (ALTO) is an IETF standardized protocol that provides abstract network topology and cost maps in addition to endpoint information services that can be consumed by applications in order to become network-aware and take optimized decisions regarding traffic flows. In this work, we propose a public service based on the ALTO specification using public routing information available at the Brazilian Internet eXchange Points (IXPs). Our ALTO server prototype takes the acronym of AaaS (ALTO-as-a-Service) and is based on over 2.5GB of real BGP data from the 25 Brazilian IX.br public IXPs. We evaluate our proposal in terms of functional behaviour and performance via proof of concept experiments which point to the potential benefits of applications being able to take smart endpoint selection decisions when consuming the developer-friendly ALTO APIs.MMauch HOC presentation-oct-04-2013

A Computational Study Of Traffic Assignment Algorithms
The document summarizes a study comparing algorithms for solving traffic assignment problems. It classified algorithms as link-based (using link flows), path-based (using path flows), or origin-based (using link flows from origins). It reviewed literature on algorithms like Frank-Wolfe (link-based), path equilibration (path-based), and origin-based algorithm. It chose to implement representative algorithms from each class: Frank-Wolfe, conjugate Frank-Wolfe, bi-conjugate Frank-Wolfe (link-based), path equilibration, gradient projection, projected gradient, improved social pressure (path-based), and Algorithm B (origin-based) to compare their performance on benchmark problems.

Vehicular ad-hoc networks, when combined with wireless sensor networks, are used in a variety of solutions for commercial, urban, and metropolitan areas, including emergency response, traffic, and environmental monitoring. In this work, we model buses in the Washington, DC Metropolitan Area Transit Authority (WMATA) as a network of vehicular nodes equipped with wireless sensors. A simulation tool was developed, using the actual WMATA schedule, to determine performance metrics such as end-to-end packet delivery delay. In addition, a web-based front-end was developed, using the Google Maps API, to provide a user-friendly display and control of the network map, input parameters, and simulated results. This application will provide users with a simplified method for modifying network parameters to account for a number of parameters and conditions, including inclement weather, traffic congestion, and more.

Nsgic annual status_briefing v0.2
The document discusses the Transportation for the Nation Strategic Plan Update project. It provides an overview of stakeholder outreach conducted to date which indicates strong support for creating a nationwide transportation dataset. A potential vision is outlined where a baseline geometry dataset containing basic road attributes could be established using an expanded Highway Performance Monitoring System (HPMS) reporting requirement. Individual stakeholders could then add "special sauce" enhancements to the baseline data. Challenges include varying data quality between states and coordinating a nationwide effort. Benefits to different stakeholders are discussed, including improved safety mapping and data sharing capabilities.
Innovative Approaches for the collection of road transport statistics
By extracting data from Enterprise Resource Planning (ERP) and Transport Management (TM) systems, particularly larger companies can easily generate data for official reporting obligation and directly transfer it to the National Statistical Institution (NSI).

This document describes a prototype application that predicts a user's travel routes based on their travel history in order to provide customized traffic advisories. It uses machine learning techniques to identify important locations from GPS and other sensor data. Routes between locations are learned from GPS data sequences and frequent routes are identified. When the user is predicted to leave a location, the application checks for traffic along likely routes and issues alerts if congestion exceeds normal levels for that route and time. A field study evaluated user acceptance of the advisories delivered by the application during transitions between locations.

Abstract:
Much attention has been attracted to the research of cooperative automatic driving that focuses on safety and efficiency by sharing the data obtained from sensor information of a vehicle. In addition, dynamic maps, a common information and communication platform for the integrated management of shared sensor information, are under consideration. A vehicle always sends data to a server that manages the dynamic map, and the server runs applications for driving support and control on the basis of the data, so fast information processing is required. However, congestion is a concern when data is continuously sent from vehicles to the server at high transmission intervals and when many vehicles are managed by dynamic maps on the server. In addition, the data transmission interval from the vehicle required by the road characteristics differs in actual traffic environments. Therefore, congestion can be alleviated by adjusting the transmission interval of data from the vehicle in consideration of road characteristics. In this paper, a platform for a dynamic map consisting of a server and a vehicle is constructed. We have also implemented a priority processing function that sets the priority for each section of a lane, and adjusts the transmission interval on the basis of the characteristics of the road around the vehicle.
Predicting Operating Train Delays into New York City using Random Forest Regr...
The Long Island Railroad operates one of the largest commuter rail networks in the U.S.[1]. This study uses data which includes the location and arrival time of trains based on onboard GPS position and other internal sources. This paper analyzes the GPS position of the train to gain insight into potential gaps in on time performance and train operations. This was done by developing a Random Forest Re-gression model [2] and an XGBoost regression model [3[. Both models prove to be useful to make such predictions and should be used to help railroads to prepare and adjust their operations.

Improving the quality and cost effectiveness of multimodal travel behavior da...
Multimodal transportation such as transit, bike, walk, transportation network companies (TNCs) (e.g., Uber, Lyft), car share, and bike share are vital to supporting livable communities. However, current data collection techniques for multimodal travel behavior, including apps built specifically for travel behavior surveys, have limitations (e.g., significant negative impact on battery life, user acquisition) which prevent a better understanding of significant real-world challenges (e.g., multimodal traveler choices, relationships between travel behavior and health).
This webinar discusses the results of a recently completed research project funded by the National Center for Transit Research, “Improving the Quality and Cost Effectiveness of Multimodal Travel Behavior Data Collection”. In this project, the research team developed and deployed a proof-of-concept system to collect multimodal travel behavior data on an ongoing basis directly from users of a popular open-source mobile app for multi-modal information, OneBusAway (OBA). To overcome battery life challenges, the research team used the Android Activity Transition API, which leverages hardware advancements in modern mobile phones.
This webinar presents the technology used to implement this data collection tool, as well as the results of a pilot deployment to 676 beta testing users. Over 10 weeks, 74 users opted into the study without any incentive and contributed 65,582 trips. Key concerns discussed for data collection when conserving battery life include the timeliness and accuracy of data.

TRB 2020 - Cybersecurity Vulnerabilities in Mobile Fare Payment Applications:...
Presentation of a TRB 2020 paper (available at http://bit.ly/trb-cyber-mobile-fare-app):
Mobile fare payment applications are becoming increasingly commonplace in the public transportation industry as both a customer convenience and an effort to reduce fare management costs and improve operations for agencies. However, there is relatively little literature on vulnerabilities and liabilities in mobile fare payment applications. Furthermore, few public agencies or supporting vendors have policies or established processes in place to receive vulnerability reports or patch vulnerabilities discovered in their technologies. Given the rapidly increasing number of data breaches in general industry IT systems, as well as the fact that mobile fare payment apps are a nexus between customer and agency financial information, the security of these mobile applications deserve further scrutiny. This paper presents a vulnerability discovered in a mobile fare payment application deployed at a transit agency in Florida that, due to the system architecture, may have affected customers in as many as 40 cities across the United States – an estimated 1,554,000 users. Lessons learned from the vulnerability disclosure process followed by the research team as well as recommendations for public agencies seeking to improve the security of these types of applications are also discussed.

Full 2017 TRB paper at http://bit.ly/TRB2017-GTFS.
The General Transit Feed Specification (GTFS) describes fixed-route public transportation service to facilitate integration of transit information into various applications. The purpose of this report is to provide an overview of the opportunities to use GTFS for many different types of information services for the general public as well as internal agency operations. Many opportunities exist to create new services based on GTFS data — either to provide transit information through a greater range of delivery formats (e.g., new mobile transit applications), or to provide new ways of understanding and using transit information (e.g., for planning and analysis purposes).
For transit agencies that are not openly sharing their data, this report will inform decisions on prioritizing and justifying investments in open data initiatives surrounding GTFS.
For transit agencies that already provide open access to their GTFS data, this report will assist the agency in maximizing their investment in GTFS data by showcasing examples of many new types of applications that utilize the same GTFS data they are already producing.
For Departments of Transportation, Metropolitan Planning Organizations, and other intermodal agencies, this report will assist them in understanding the current state-of-the-art in public transportation information and will help them integrate this data into intelligent transportation systems (ITS) and multimodal traveler information systems.
OneBusAway - New issue reporting flow in OneBusAway Android
This presentation was created as an orientation to Hillsborough Area Regional Transit (HART) staff for how issues can now be reported via hte OneBusAway Android app, including management of issues related to stops and arrival times via the SeeClickFix issue management site (via Open311).
Closing the Loop - Improving Transit through Crowd-sourced Information
Offering real-time arrival information to riders via mobile applications has been shown to improve the rider’s perception of transit, and even increase ridership. This direct connection to riders also offers the agency an opportunity to collect feedback on how transit service and infrastructure can be improved. However, managing the sheer volume of this rider feedback can be very challenging, especially when various departments and agencies (e.g., city/county government) are involved (e.g., does this broken bench belong to the transit agency or the county?). This presentation discusses a pilot project in Tampa, FL, funded by the Florida Department of Transportation and the National Center for Transit Research, which focused on the improvement of the feedback loop from riders back to transit agencies, local government, and departments of transportation. This project made improvements to the OneBusAway mobile app, originally deployed in Tampa in 2013, to include support for the Open311 standard (http://www.open311.org/) for issue reporting. Open311 support gives agencies the option of selecting a hosted issue management solution that supports Open311 such as SeeClickFix.com and PublicStuff.com, or the option to utilize existing open-source Open311-compliant software.

Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.

Power Grid Model
The global energy transition is placing new and unprecedented demands on Distribution System Operators (DSOs). Alongside upgrades to grid capacity, processes such as digitization, capacity optimization, and congestion management are becoming vital for delivering reliable services.
Power Grid Model is an open source project from Linux Foundation Energy and provides a calculation engine that is increasingly essential for DSOs. It offers a standards-based foundation enabling real-time power systems analysis, simulations of electrical power grids, and sophisticated what-if analysis. In addition, it enables in-depth studies and analysis of the electrical power grid’s behavior and performance. This comprehensive model incorporates essential factors such as power generation capacity, electrical losses, voltage levels, power flows, and system stability.
Power Grid Model is currently being applied in a wide variety of use cases, including grid planning, expansion, reliability, and congestion studies. It can also help in analyzing the impact of renewable energy integration, assessing the effects of disturbances or faults, and developing strategies for grid control and optimization.
What to expect
For the upcoming meetup we are organizing, we have an exciting lineup of activities planned:
-Insightful presentations covering two practical applications of the Power Grid Model.
-An update on the latest advancements in Power Grid -Model technology during the first and second quarters of 2024.
-An interactive brainstorming session to discuss and propose new feature requests.
-An opportunity to connect with fellow Power Grid Model enthusiasts and users.
Introduction of Cybersecurity with OSS at Code Europe 2024
I develop the Ruby programming language, RubyGems, and Bundler, which are package managers for Ruby. Today, I will introduce how to enhance the security of your application using open-source software (OSS) examples from Ruby and RubyGems.
The first topic is CVE (Common Vulnerabilities and Exposures). I have published CVEs many times. But what exactly is a CVE? I'll provide a basic understanding of CVEs and explain how to detect and handle vulnerabilities in OSS.
Next, let's discuss package managers. Package managers play a critical role in the OSS ecosystem. I'll explain how to manage library dependencies in your application.
I'll share insights into how the Ruby and RubyGems core team works to keep our ecosystem safe. By the end of this talk, you'll have a better understanding of how to safeguard your code.

2011 ITS World Congress - GO-Sync - A Framework to Synchronize Transit Agency Datasets with Online Communities
- 1. GO-SYNC A FRAMEWORK TO SYNCHRONIZE TRANSIT AGENCY DATASETS WITH ONLINE COMMUNITIES Khoa Tran, Ed Hillsman, Sean Barbeau, Miguel Labrador ktran9@mail.usf.edu, hillsman@cutr.usf.edu, barbeau@cutr.usf.edu, mlabrador@usf.edu Department of Computer Science and Engineering & Center for Urban Transportation Research University of South Florida http://code.google.com/p/gtfs-osm-sync/ Open-Source on:
- 2. GO-SYNC MOTIVATION & CHALLENGES • Shortcomings of official transit General Transit Feed Spec. (GTFS) datasets • Lack of transit data in OpenStreetMap (OSM) for many U.S. cities • Goal – create an open-source software tool that can: – Share transit agency data with OSM community – Leverage social mapping model to improve bus stop inventory, and allow agency to retrieve these improvements MOTIVATIO N CHALLENGE S • Lack of a strict tagging system in OSM • Avoid duplicating OSM data & respect work done by other users • Ongoing updates to GTFS (and OSM) data • Integration of crowd-sourced data into transit agency internal datasets
- 3. GTFSOSM(GO)-SYNC FRAMEWORK DESIGN 1. Determine what has already been mapped in the OSM in the area covered by the GTFS data. 2. Identify bus stops that may be in conflict between OSM and an agency’s GTFS data 3. Make decisions on how to manage conflicts, with the aid of user input. 4. Upload GTFS data into OSM, managing any conflicts that the agency cannot reconcile. 1) Input GTFS data and Agency Info 2) Analyze before Upload
- 4. EVALUATION IN TAMPA & COLLABORATION •July 2010 - 3,812 new HART stops uploaded (133 stops previously existed) •Jan. 2011 -173 modifications were made RETRIEVING IMPROVEMENTS TO TRANSIT AGENCY EVALUATIO N 1. Output as a GTFS file, using GTFS-defined fields when possible 2. Additional “OSM_TAGs” field name is inserted at the end of the row 3. Additional tags from OSM (i.e. “key=value”) are separated by “|” (i.e., pipe-delimited) Example: stop_id,stop_name,stop_lat,stop_lon, OSM_TAGs 881,Fletcher Av @ Livingston Av,28.0693,-82.4272, shade=no|ntd_id=4041 |shelter=no|bench=no| note=field checked after upload
