The topic of the September 10, 2016 FSUTMS Users Group Meeting is Multimodal Model Development and Application. This meeting will feature presentations on newly released Florida Statewide Model with its passenger and freight component, and multimodal planning studies using regional and project level models:
The first presentation is titled “Introduction to Florida Statewide Model, Version 6.0 (FLSWM V6.0)”, and It will be given by Mr. Thomas Hill, Florida Department of Transportation (FDOT), Transportation Data & Analysis Office. This presentation will provide an overview of the development and application of the newly released FLSWM 6.0 model including the passenger model and the Integrated Freight Supply-Chain Intermodal Model (FreightSIM) components. The model can be used for statewide corridor passenger and freight analysis.
The second presentation is titled “A Tour of FTA's STOPS Applications to Large, Medium and Small MPOs”, and will be presented by Amar Sarvepalli of Parsons Brinckerhoff. The FTA STOPS application was originally developed as a means to review transit forecasts submitted as part of funding requests under the New Starts program. Due to its simplified structure and ease of use, it is now often used by project sponsors in lieu of regional travel demand models to develop ridership forecasts. This presentation compares and contrasts the use of STOPS to projects located in large (San Diego, Los Angeles), medium (Indianapolis, Virginia Beach) and small (Lexington, KY) cities. The presentation covers a brief overview of the context that led to the use of STOPS in each of these cities, including a particular case where it was applied to validate forecasts prepared with a regional travel demand model. In addition, it showcases the use of open-source tools developed for analyzing and presenting STOPS results.
The third presentation is titled “Estimating Trip Internalization at Mixed Use Developments: A Novel Approach”, and will be presented by Chang-Jen Lan, Ph.D., P.E of City of Jupiter, FL. Trip internalization is one of the key determinants to achieve long-term sustainability of mixed-use developments and sufficient traffic concurrency. Underestimating the magnitude of internal captures diminishes the traffic benefit of mixed-use development and could cause undue impact fees and development costs to developers for possibly unwarranted mitigations. On the contrary, overstating internal captures will eventually impose financial burden on government agencies to rectify deficient traffic mitigations using public funds or the public will suffer from more congestion otherwise. The uncertainty associated with internalization provokes constant debates among the competing interests, which need to be addressed to promote desirable mixed-use developments. This study focuses on developing a systematic methodology to more accurately estimate and predict trip internalization within mixed-use developments. The estimation results indicate that, except the distances among uses, all the parameters are statistically significant. The validation against cordon counts shows the overall internalization rates predicted from ten study sites were greatly enhanced to 86% accuracy based on R-square, with 4.3% root mean squared error (RMSE) and a slight overestimation (1.8%) on the average, a substantial improvement over the existing methodology. The presentation will also include a live demonstration of an Excel spreadsheet application that automates the estimation procedure and show some case studies to compare with the existing ITE and NCHRP approaches.
By attending the Users Group meeting, participants will learn the new methodologies of analyzing multimodal transportation planning projects using the data and tools available and make informed decisions.
