The document discusses key issues and limitations related to transportation modeling for planning purposes. It notes that models provide insights, not definitive answers, and results must be interpreted based on inherent uncertainties and limitations. Precision of model outputs must be balanced with accuracy in context of the planning question being addressed. The scale of the model and associated data may not match the scale of the specific planning issue.

Abstract
One of the most persistent problems faced by the San Francisco County Transportation Authority (the Authority) is that of handling a growing collection of counts. Traffic, pedestrian and bicycle counts have been collected by staff, consultants and sister agencies for numerous planning studies at various locations in San Francisco over the years. But how should these counts be organized? Some are in Excel workbooks of varying and spontaneous formats, others consist of scanned handwritten documents, and finally some are on (gasp!) paper.
Since the modeling team at the Authority has a continuous need for these counts in order to calibrate and validate the travel demand model as well as to inform model development, these counts have come under the team’s purview. After a couple of failed attempts to standardize Excel formats and directory structures, the modeling team decided to modernized its counts management system. The Authority first explored proprietary software products, but found them either too expensive, cumbersome, or inflexible. Instead, Authority staff embarked on developing Count Dracula, an open source counts management tool. Count Dracula’s aim is to make uploading, downloading and querying counts easy for Authority staff as well as other interested parties outside the organization. The Count Dracula code base has been designed to be reusable by other agencies with similar needs, and it’s built on GeoDjango, a geographic web framework.
Count Dracula includes a web-based map GUI for visualizing where counts are located (and where more counts are needed), and it includes a query interface so that specific types of counts can be batch-downloaded (for example, midweek counts from the last three years). As it was developed by a modeling team, there is a specific emphasis on counts seamlessly interfacing with model transportation networks. Counts can also be uploaded using this interface, and moderated through an admin interface. This presentation will explain the development of Count Dracula and convince everyone attending to download it and dive in.

This paper compares the potential benefits and impacts of two types of congestion pricing: oad- or cordon-based, and parking-based, that the San Francisco County Transportation Authority studied as a part of the Mobility, Access, and Pricing Study. The study is evaluating comprehensive pricing and mobility-enhancing packages to improve access and offer more sustainable travel choices to and within San Francisco. The Study Team evaluated the cordon and parking congestion charges using the SF-CHAMP regional travel demand model (also known as RPM-9). This paper discusses the current representation of parking in SF-CHAMP and its limitations, and then summarizes the development of an improved parking representation including additional data needs.
This paper evaluates the performance of the San Francisco County Transportation Authority’s recently-enhanced Nine-County Regional Pricing Model (RPM-9), which is being used to study congestion pricing alternatives in San Francisco as a part of the Mobility, Access, and Pricing Study. This study sought to evaluate comprehensive pricing and mobility-enhancing packages to improve access and offer more sustainable travel choices to and within San Francisco. The Study tested various pricing scenarios including cordon, area, and gateway designs; various toll levels; and a range of shoulder pricing/time of day profiles. Pricing scenarios were coupled with strategies for improving accessibility for all modes of travel to, from, and within San Francisco including, but not limited to, local and regional transit investments. RPM-9’s structure as a tour-based microsimulation model allowed several enhancements for this study that would not have been possible in a trip-based framework. These include the use of value-of-time distributions, rather than averages across groups; the feedback of mode and destination choice logsums to make auto ownership and tour generation sensitive to price; the explicit tracking of travelers who have paid area tolls; and enhanced peak spreading models. The disaggregate nature of RPM-9 facilitated summaries of key measures of effectiveness at various levels and types of aggregation including income level, residential location, and work location. These flexible summaries were critical to evaluating alternatives and answering questions about who was paying versus who was benefiting.

LF Energy Webinar: Electrical Grid Modelling and Simulation Through PowSyBl -...DanBrown980551
Do you want to learn how to model and simulate an electrical network from scratch in under an hour?
Then welcome to this PowSyBl workshop, hosted by Rte, the French Transmission System Operator (TSO)!
During the webinar, you will discover the PowSyBl ecosystem as well as handle and study an electrical network through an interactive Python notebook.
PowSyBl is an open source project hosted by LF Energy, which offers a comprehensive set of features for electrical grid modelling and simulation. Among other advanced features, PowSyBl provides:
- A fully editable and extendable library for grid component modelling;
- Visualization tools to display your network;
- Grid simulation tools, such as power flows, security analyses (with or without remedial actions) and sensitivity analyses;
The framework is mostly written in Java, with a Python binding so that Python developers can access PowSyBl functionalities as well.
What you will learn during the webinar:
- For beginners: discover PowSyBl's functionalities through a quick general presentation and the notebook, without needing any expert coding skills;
- For advanced developers: master the skills to efficiently apply PowSyBl functionalities to your real-world scenarios.
PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

3. How much does expected traffic on
Gold Rush Parkway drop when
we add the BRT facility?
A. I don’t know. The model is still running
B. 6,765.7 vehicle trips per day
C. Hmmm, actually, traffic increased!
D. 6% compared to the “No-Project” scenario
4. If we implement “Smart Growth”
land use policies, can we take Gold Rush
Parkway off our long-range project list?
A. But all I have is a traffic model!
B. The model says increased density leads to
increased tripmaking in all modes. Uh-oh!
C. Results suggest the parkway will still be
necessary unless the growth is accompanied
by robust transit at all times of day.

7. Insights, not Answers:
How do we translate from “Results” to “Insights?”
Telling the story is harder than running the model.
All numbers are relative!
Results must be interpreted based on constraints and
limitations of the models.
The story includes the path to the results, not just
the final answers.

How robust are your strategies, given certain
uncertainty?

It may or may not be
accurate, as well.

14. Limitations of Modeling
As modelers, we need to be honest in facing
the ways models are inappropriate
for the questions at hand.
As planners, you need to be aware of model and
data shortcomings, so you can make
informed decisions.
