Traffic is one of the most significant problem in Sri Lanka. Valuable time can be saved if there is a proper way to predict the traffic and recommend the best route considering the time factor and the people’s satisfaction on various transportation methods. Therefore, in this research using location awareness applications installed in mobile devices, data related to user mobility were collected by using crowdsourcing techniques and studied. Based on these observations an algorithm has been developed to overcome the problem. By using this, the best transportation method can be predicted as the results of the research. Therefore, people can choose what will be the best time slots & transportation methods when planning journeys. Throughout this research it has been proven that for the Sri Lankan context, the data mining concepts together with crowdsourcing can be applied to determine the best transportation method.

Land use and transportation planning are inter-dependent, as well as being important factors in forecasting urban development. In recent years, predicting traffic based on land use, along with several other variables, has become a worthwhile area of study. In this paper, it is proposed that Deep Neural Network Regression (DNN-Regression) and Recurrent Neural Network (DNN-RNN) methods could be used to predict traffic. These methods used three key variables: land use, demographic and temporal data. The proposed methods were evaluated with other methods, using datasets collected from the City of Calgary, Canada. The proposed DNN-Regression focused on demographic and land use variables for traffic prediction. The study also predicted traffic temporally in the same geographical area by using DNN-RNN. The DNN-RNN used long short-term memory to predict traffic. Comparative experiments revealed that the proposed DNN-Regression and DNN-RNN models outperformed other methods.
There is a pretty reasonable chance that Southampton (despite recently scoring 2nd in a detailed review of all the paeds cardiac centres – see below) will lose paeds cardiac surgery.
This has obvious implications for children within wessex and the channel islands with CHD
Less obviously it will have a significant effect on the bed numbers and structure of the paeds ICU
Also it will be to the detriment of the ability of SUHT to offer a comprehensive service to children for our region.
The form is tedious, but hopefully the more people they have who make a noise, the smaller the chances of this brilliant service being dismantled

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.
The many-uses-of-gtfs-data-–-its-america-submission-abbreviatedCTeixeira2
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.

This is the paper I presented for the WICT 08 Conference. The objective of this study looks at enhancing Open Source routing algorithms by adding functionalities and variables that favour fuel savings as well as shortest route. A system is developed using Open Source GIS (using the PostGIS and pgRouting extensions for the DBMS: PostgreSQL), whereby a number of variables, including weather conditions, road network, traffic status, vehicle specification data and road gradient are manipulated by the user to achieve shortest and most fuel efficient route. This study also provides neighbouring techniques for emergency response teams, so as to traverse the shortest route to an accident.

AbstractWe design an software to find optimal(shortest) path .docxaryan532920
Abstract
We design an software to find optimal(shortest) path on the University of Minnesota map by using the A* algorithm. Using GUI (Graphical User Interface) to visualize the path on the map and print the list, which contains the transient nodes. It is definitely efficient way for students to make route planning in the campus. The approach supports that query the shortest path and manage the time in the campus.
Maps are kind of diagrammatic form that represents physical features such as buildings and roads, and maps play an essential role in the development of civilization. Most of people are familiar with using maps to find routes and locate their position on the maps. However, it is very challenge to find a shortest path in the real world. Therefore, using computers and algorithms are efficient ways to solve route planning problems. Using graph theories to take the place of real buildings and available roads with nodes and edges, then a transportation network has been established by connecting them. Meanwhile, computer software can generate a shortest path in such transportation network. The path shows the optimal solution in the corresponding transportation network, what is more, the tool we designed should be tested against real world, complex situation in order to detect any bugs existing in it.
Map is a graphic way to represent spatial concepts. A type which people most familiar with is transportation map. Map is a medium of interaction between human and environment. That is because vision of human cannot satisfied human when they make plan according to environment. An accurate map could help human to learn where they are, and make correct decision. For the record, Napoleon Bonaparte did that we owe the first systematic use of maps in the conduct of war. \cite{p2}Accurate information on map helped French Emperor to coordinate geographically expansive campaigns and discrete armies in the field. They indicate positions of enemy armies and do prediction by labelling on map. By calculating distance and highlighted important topographical features on map, predication could be much more accurate. As “a means of visualizing and managing the future,” the Napoleonic map was “the central part of an information-transformation system”\cite{p3}
Technology helped map develop more quickly. Map helps human learn a more accurate world, and also makes life of human more convenient. For example, when students join a new university, or they want to know about campus, students could use visual map software installed in smartphones to get rough idea about it. Map cannot show all detail about each building in campus but it could provide students the most accurate shapes of buildings in vertical view, distance between them and relations of positions. All these information could help students to learn their campus better. However, it is difficult for some of students to find a route between two location in a complicated campus which is with a big ar.

Optimal content downloading in vehicular network with density measurementZac Darcy
The existence of Internet-connected navigation and infotainment systems is becoming a truth that will easily lead to a remarkable growth in bandwidth demand by in-vehicle users. In Examples the applications of vehicular communication proliferate, and range from the updating of road maps to the repossession of nearby points of interest, downloading of touristic information and multimedia files. This content downloading system will induce the vehicular user to use the resource to the same extent as today’s mobile customers. By this approach communication-enabled vehicles are paying attention in downloading different contents from Internet-based servers. We summarize the performance limits of such a vehicular multimedia content downloading system by modeling the content downloading process as an effective problem and developing the overall system throughput with density measurement. Results highlight the methods where the Roadside infrastructure i.e., access points are working at different capabilities irrespective of vehicle density, the vehicle-to-vehicle communication.
The increasing need for traffic detection system has become a vital area in both developing and developed
countries. However, it is more important to get the accurate and valuable data to give the better result
about traffic condition. For this reason, this paper proposes an approach of tracking traffic data as cheap
as possible in terms of communication, computation and energy efficient ways by using mobile phone
network. This system gives the information of which vehicles are running on which location and how much
speed for the Traffic Detection System. The GPS sensor of mobile device will be mainly utilized to guess a
user’s transportation mode, then it integrates cloud environment to enhance the limitation of mobile device,
such as storage, energy and computing power. This system includes three main components: Client
Interface, Server process and Cloud Storage. Some tasks are carried out on the Client. Therefore, it greatly
reduces the bottleneck situation on Server side in efficient way. Most of tasks are executed on the Server
and history data are stored on the Cloud Storage. Moreover, the paper mainly uses the distance based
clustering algorithm in grouping mobile devices on the same bus to get the accurate data.

WHITE PAPER: Data Harmonization & Interoperability in OpenTransportNetplan4all
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.
This white paper presents a spatial decision support system (SDSS) aimed at generating optimized vehicles routes for multiple vehicles routing problems that involves serving the demand located at nodes of a transportation network. The SDSS incorporates MapPointTM (cartography and network data), a database and a metaheuristic developed generate routes.
Climate Science Flows: Enabling Petabyte-Scale Climate Analysis with the Eart...Globus
The Earth System Grid Federation (ESGF) is a global network of data servers that archives and distributes the planet’s largest collection of Earth system model output for thousands of climate and environmental scientists worldwide. Many of these petabyte-scale data archives are located in proximity to large high-performance computing (HPC) or cloud computing resources, but the primary workflow for data users consists of transferring data, and applying computations on a different system. As a part of the ESGF 2.0 US project (funded by the United States Department of Energy Office of Science), we developed pre-defined data workflows, which can be run on-demand, capable of applying many data reduction and data analysis to the large ESGF data archives, transferring only the resultant analysis (ex. visualizations, smaller data files). In this talk, we will showcase a few of these workflows, highlighting how Globus Flows can be used for petabyte-scale climate analysis.

Understanding Globus Data Transfers with NetSageGlobus
NetSage is an open privacy-aware network measurement, analysis, and visualization service designed to help end-users visualize and reason about large data transfers. NetSage traditionally has used a combination of passive measurements, including SNMP and flow data, as well as active measurements, mainly perfSONAR, to provide longitudinal network performance data visualization. It has been deployed by dozens of networks world wide, and is supported domestically by the Engagement and Performance Operations Center (EPOC), NSF #2328479. We have recently expanded the NetSage data sources to include logs for Globus data transfers, following the same privacy-preserving approach as for Flow data. Using the logs for the Texas Advanced Computing Center (TACC) as an example, this talk will walk through several different example use cases that NetSage can answer, including: Who is using Globus to share data with my institution, and what kind of performance are they able to achieve? How many transfers has Globus supported for us? Which sites are we sharing the most data with, and how is that changing over time? How is my site using Globus to move data internally, and what kind of performance do we see for those transfers? What percentage of data transfers at my institution used Globus, and how did the overall data transfer performance compare to the Globus users?

Understanding Public Transport Networks using Free and Open Source Software
1. UnderstandingPublicTransportNetworksusing
FreeandOpenSourceSoftware
Patrick Sunter: PhD Candidate in Architecture Building and Planning, University of
Melbourne
Presentation 12 May in GEOM90008, Foundations of Spatial Information Subject
Acknowledgment: maps produced during this presentation have been part of
collaborative work with Beyond Zero Emissions (BZE).
2. Context of my PhD
Interpretive Action-Research Paradigm
using:-
Co-Development of Tools
Participant Observation
Interviews,
Focus Groups,
Artifact Analysis
PhD: Focus is on exploring Free & Open Source software as a potential
means of increasing civil society organisation’s ability to engage with
Metropolitan-scale transport planning and propose alternative futures
Partner Organisations:-
* Beyond Zero Emissions (BZE)
* Public Transport Users Association (PTUA)

3. Selecting Tools and Goals
What sort of technical analysis and communication
one can perform is a function of not just goals but
available expertise, tools, and data.
With both project partners, after design and tools
review we’ve focused on GIS-based analysis of public
transport network performance (next slide)
Work with BZE in the context of a larger project that
included aspects of 4-step model etc.
4. Target Capability: Public
Transport Network Analysis
“Travel Time Maps” (Isochrone
maps)
Display either:-
Locations reachable from a
given origin in a given time;
‘Catchment’ to reach a given
destination
Generally involve A* network
calculation but can be
optimised.
Good because they indicate
overall network quality,
including interchanges

5. Data: GTFS and OpenStreetMap
GTFS = “General Transit Feed
Specification’
developers.google.com/transit/
Emerged in mid 2000s from Portland
TriMet and Google’s 20% time
Plaintext format: Entire GTFS feed of
Portland is ~169 Mb
Live feeds available from 376+ agencies,
see:- www.gtfs-data-exchange.com/
Now available for all AU state capitals,
not yet Melbourne (though other data
released ~Mar 2014)
Quite strong ecosystem of tools, apps to
process & work with this format
(* re Territories, not sure about Darwin?)

6. OpenTripPlanner
Open Source software that at core is a fast Journey Planner
(algorithms for time-dependent route-finding), collaboration
between Portland’s TriMet and several researchers, + OpenPlans
organisation
Primarily Java-based, built on other standards and software such
as Tomcat (web services), Leaflet for web application.
7. Progress with OpenTripPlanner
With a mixture of running existing Open Source tools –
especially OpenTripPlanner and Quantum GIS, and some
scripting and GIS work, we’ve developed useful visualisations.
9. Extending Potential to ‘Before
and After’ Analysis
Workflow:-
Assembling original new routes and stops as
Shapefiles
Running scripts (using PostGIS, GDAL) to convert
these routes to a ‘topological network’ of
segments, stops, with metadata like average
speed attached.
Converting these topological files to network
formats needed, such as GTFS, or Netview scripts
In OpenTripPlanner’s case, building a connected
‘graph’ of street network, timetables, transfer
11. before & after example maps

Right: same location & time, but with revised bus network and ‘best case’ service (30km/h avg
speed, 5min headways, implies significant road prioritisation measures)
12. Futher Potential of this kind of GIS-
based network analysis

Right: Mode “Accessibility gap” in Washington D.C. between car and
public transport, plus employment
