Developing an Active Traffic Management System for I-70 in Colorado.PI: Dr. Mohamed Abdel-Aty Sponsored by the Colorado Department of Transportation. Start Date: Monday, March 21, 2011 End Date: Wednesday, June 20, 2012 Contractual Amount: $124,967.00 Project Scope: Develop a system to incorporate Variable Speed Limits based on advanced algorithms to improve traffic turbulence in real-time and therefore reduce crash risk and improve flow. Since traffic data for the freeway are collected continuously it is possible to develop models using historical incident data and apply them in real-time to examine the traffic data for detecting any incident that might have occurred on the freeway.
Experiments on Driving under Uncertain Congestion Conditions and the Effects on Traffic Networks from Congestion Pricing Initiatives.Project Scope: We propose to conduct laboratory and field experiments to test the effects of various congestion pricing initiatives for highways. The project involves CATSS at the College of Engineering at UCF, the Department of Economics at GSU, and the Advanced Performance Technology Group at IST. Project focuses on risk perceptions and risk attitudes among drivers facing congestion charges during their daily commute. Using naturalistic cues in virtual reality simulations and natural cues in field settings research participants are presented with decision tasks and observations are used to estimate and test various decision models.
Developing Advanced Spatial Analysis Tools in Transportation Safety Planning: Examining Planning Zones and Trip Data
PI: Dr. Mohamed Abdel-Aty Sponsored by Federal Highway Administration/USDOT Start Date: Tuesday, March 8, 2011 End Date: Friday, September 7, 2012 Contractual Amount: $118,876.00 Project Scope: Objectives of this project are: Objective 1: To establish the suitability of current traffic-related zoning approach in the new generation planning method: Transportation Safety Planning (TSP). Objective 2: To explore the effective and efficient use in TSP of existing key determinants in traditional transportation planning (TP) such as trip generation/distribution data. Objective 3: Based on the accomplishment of objectives 1 and 2, to develop a prototype of a scientific, while practical, spatial analysis toolbox to advance TSP practice at various levels.
Dynamic Flashing Yellow Arrow (FYA) - A Study on Variable Left Turn Mode Operational and Safety Impacts
PI: Dr. Essam Radwan Sponsored by the Florida Department of Transportation Start Date: Tuesday, May 8, 2012 End Date: Tuesday, December 31, 2013 Contractual Amount: $200,000 Project Scope: There is a need to develop an INTERACTIVE and EFFICIENT framework to serve as a decision support system for the evaluation of left turn phasing alternative base on intersection conditions. This framework will allow (1) an interactive evaluation of left turn phasing and ultimately recommend phasing mode by time-of-day (2) Traffic Management Center (TMC) data can be fed into the decision support system and intersections requiring attention/modification of left turn mode will be flagged.
