Title:

Evaluations of Managed Lane Strategies for Arterial Deployment of Cooperative Adaptive Cruise Control

Abstract:

Evolving from adaptive cruise control, cooperative adaptive cruise control (CACC) is the most advanced generation of cruise control system. Enabled by an extra layer of communication under connected vehicle (CV) environment, CACC has gained an increasing attention due to its technology readiness that can achieve rapid deployment compared to other CV applications. Recently, combining with managed lane strategy, CACC has become a game changer to dramatically elevate the capacity of highway without any significant investment for lane-mile increase. Applying CACC for arterial managed lane strategy, this paper presents the findings obtained from the simulation-based evaluation results. Divided into three arterial managed lane strategy categories dealing with 1) mixed-traffic, 2) restricted CACC lane, and 3) dedicated CACC lane, a VISSIM-based simulation test bed is constructed with an actual corridor located in Fairfax, Virginia. With intersection average stop delay, average speed, and throughput as the measures of effectiveness, simulation results show that the implementation of dedicated CACC lane strategies would be improper for the improvement of intersection performance until the market penetration of CACC reaches a sufficient level as much as the capacity of one driving lane. On the other hand, it is revealed that the mixed-traffic and restricted CACC lane strategies outperform the dedicated lane strategy, thereby resulting in 5% to 25% stop delay reductions, depending on the market penetration rates.
