Safety Effects of Connected and Automated Vehicle-Based Variable Speed Limit Control near Freeway Bottlenecks considering Driver’s Heterogeneity

Algorithm 1

Central control module algorithm.

Input: The total simulation time, ; the number of detectors, N; the control cycle, the average speed collected from loop detector station at the location at time , ; the desired deceleration, ; the perception reaction time, ; the average length of the vehicles, ; the average occupancy at location at time , .
Output: The calculated speed limit, ;
