Overview

BAPA continues to partner with the FSUTMS User Group Region 4 FDOT to provide members with the latestest developments in forecasting models and best practices for transportation planning. 

The first presentation is titled “Implementing a Subarea Mesoscopic Dynamic Traffic Assignment Model Using Big Data Sources In Richmond VA”, and It will be given by Mr.Srinivas Varanasi, The Corradino Group.

Transportation Planning agencies have been aiming the efficiency in data collection methods for a long time. The implementation of efficient modeling systems for corridor and subarea planning require rigorous data collection and resources. The Richmond Regional Transportation Planning Organization (RRTPO) has been focusing on innovative methods of minimizing data collection costs using the BIG Data (Streetlight OD and Travel time data).  Secondly, the TPO wants to address issues with static assignment models by considering que lengths in patch choice behavior of the travelers. 

The second presentation is titled “Design Traffic Detectors for Better Data Accuracy, Examples For FDOT D5 I-4 Express Lanes”, by Mr.Jingcheng Wu, PE, PTOE, HDR.

Dr. Wu will provide an introduction to the state-of-the-practice of traffic detectors, discuss how traffic detectors collect volume, speed and occupancy data, review the detector data quality and validity, and demonstrate how to design a vehicle detection system to providebetter data accuracy.  This presentation will help practitioners and researchers understand how detector data are collected in practice so that the data can be better used for traffic engineering and planning. Examples For FDOT D5 I-4 Express Lanes will also be discussed.

The third presentation is titled “Pedestrian Crosswalk Field Data Collection: Lessons Learned and Experiences”, by Mr. Richard Driscoll & Kurt Lehmann, Cambridge Systematics.

Crossing a street at an uncontrolled crosswalk can be difficult for pedestrians.  Although Florida law requires all vehicles to stop for pedestrians in these crosswalks, drivers often fail to comply.  Many factors account for this, but lack of crosswalk recognition and failure to abide are major contributors to crossing point issues and crashes at uncontrolled crosswalks. FDOT, supported by Cambridge Systematics, HNTB, and Dr. Ron Van Houten of Western Michigan University, is conducting a study to determine the efficacy of R1-6a signs on yielding behaviors at selected Florida crosswalk locations. This presentation shares some experiences from our field data collection.
