A Comparative Study of Adaptive Cruise Control System based on Different Spacing Strategies

Abstract

Recently, the trend of effective driving research has received more attention, they improve the overall traffic flows and individual driving performances on urban roads, especially at intersections where arterial congestion urban areas causing the decreasing of its capacity, the solution to the problem is to use advanced control systems in the field of intelligent transportation systems. In this study, such a solution is presented by using the adaptive cruise control (ACC) system of vehicle platoons based on the constant spacing (CS )strategy and constant time headway (CTH) strategy.Simulated the vehicle platoons at the signalized intersection to analyze the advantages and disadvantages of two distance strategies through string stability analysis, improving the urban arterial capacity. Additionally, the smart car prototype in a platoon is introduced and is tested for the ACC system based on the CS strategy with the aim of verifing for the practicability and effectiveness between the theory and the experiment. The proposed approaches were test and simulated and the results were analyzed providing some conclusions related to their efficiency.
