Highway congestion due to incidents and bottlenecks is a frequent phenomenon in most Urban highways. Understanding the mechanisms of congestion and finding ways to better control traffic flow in order to prevent or better manage congestion will have a significant impact on travel times, fuel savings and emissions. The project objectives are to design, analyze and evaluate traffic flow controllers to deal with congestion during incidents and bottlenecks for all possible demands and roadway characteristics. The specific objectives are: Design effective lane change controllers which will recommend vehicles to change lanes early enough before reaching the bottleneck or the incident; Develop variable speed limit controllers and combine them with lane change control in order to smooth traffic flow upstream bottlenecks and incidents; Combine the variable speed and lane change controllers with ramp metering control; Demonstrate the effectiveness of the integrated lane change/variable speed/ramp metering control using microscopic traffic simulation model of I-710.
