There have been a number of enhancements made to the new regional travel forecasting model SERPM 7.0 over the past few months. New guidelines have been developed to help the users conduct site impact studies. The meeting features two (2) technical presentations:
The first presentation is titled “Enhancements to SERPM7.0 ABM”, and It will be given by Mr. Aditya Katragadda of the Corradino Group. This presentation focuses on the enhancements made to SERPM7 ABM that includes input highway and transit network improvements, 2010 Traffic Counts, observed speeds and travel time, and a new air quality evaluation program. The input network format has been changed from geodatabase to CUBE-based .net and .lin format to enhance user-friendliness. The input network now consists of the traffic counts by time of day. The observed speed and travel time variables are added to the input network. The Population Synthesizer 3 program was used to generate inputs, which enhanced quality of the population input data. The new air quality evaluation program estimates various pollutant burdens on every link, and creates daily and period-specific summaries of pollutant burden by area type and facility type, by county and FDOT district. The procedure develops emission rates from new MOVES factors provided by FDOT.
The second presentation is titled “Site Impact Studies using SERPM 7.0 – Methodology and Application”, and will be presented by Raghu Sidharthan of WSP Parsons Brinckerhoff. This presentation describes guidelines and procedures to use SERPM 7.0 to quantify the traffic impacts of land use developments. The developments covered by these guidelines are those that produce and attract trips, such as a new residential development. The first objective of the guidelines is to streamline the analysis pathway so that before vs after comparisons for a development can be performed correctly and with minimal Monte Carlo error. The second but equally important objective is to implement a household sampling scheme that saves run time without adversely affecting the accuracy of results. The presentation will discuss the background, methodology and software changes implemented followed by a step-by-step guide to a sample site impact application.
By attending the Users Group meeting, participants will learn new directions and methodologies in conducting site impact studies with the new model and better evaluating various growth management and development strategies.
