Title:

Analyzing the Benefit of Widespread use of V2I Communication for Improving Incident Management at a Congested Urban Corridor

Abstract:

Connected vehicle technology has the potential to reduce travel times along congested urban corridors. Additionally, this technology may be used to help transportation agencies manage incidents (e.g. lane closures due to an accident) in a way that causes travelers the least delay. The goal of this project is to understand and quantify the effectiveness of deploying Dedicated Short Range Communication (DSRC) technology  for a specific mobility/safety application on a specific urban corridor by creating a queue-warning  application. Effectiveness is determined by investigating the effects of connected vehicles with  active and inactive rerouting strategies on travel time reliability at different market penetration rates (MPRs) and various driver reaction times. U.S. Highway 75 (US75) in Plano, TX is simulated and results reveal that even without active reroute strategies, connected vehicles can reduce the average travel time during an accident. As the presence of connected vehicles becomes more prominent, at market penetration rates of 30% and 50%, the average travel time for all travelers on US75 is reduced and remain relatively stable at higher MPRs. Simulations of connected vehicles with lower reaction times (due to drivers’ awareness about the incident) also reveal a decrease in average travel time along the corridor, less fluctuation in travel time at higher MPRs, and increased performance similarity of the five strategies used.
