Abstract:This report presents the methodology and results of computer simulation activities supporting the development of the TOSCo system, especially the infrastructure-based algorithms. The research team also used computer simulation to evaluate the effectiveness and potential mobility and environmental benefits that could be generated through the application of the TOSCo system in both low-and high-speed corridor environments. The specific objectives of the performance analysis were to quantify the potential mobility and environmental benefits of the TOSCo system in a variety of settings and with different strategies as described below. • Different operating environments: a low-speed corridor (Plymouth Rd., Michigan) and a high-speed corridor (SH 105, Texas) • Different penetration rates of vehicles equipped with TOSCo functionality • Different connected-vehicle (CV) market penetration rates. This report assumes the use of Dedicated Short-range Communications (DSRC), but other low-latency technologies could be used. • Different infrastructure algorithms to estimate queues using information from : a basic safety message (BSM), loop-detector approach on the low-speed corridor, and a radar-based detector approach on the high-speed corridor • Different traffic control strategies: fixed-time control and coordinated actuated signal control
