In this paper, the intelligent Stop and Go system (S&G) is designed and implemented for low speed traveling vehicles in urbane area. The human-driving like fuzzy logic control is applied for achieving desired speed and safe inter-vehicle spacing. By proposed intelligent Stop and Go system, the following functions can be obtained including collision avoidance, traffic accidence reduction, driving pressure decrease, and increment of traffic capability. Furthermore, the real car equipped with sensors and a longitudinal controller is provided to demonstrate three scenarios that meet the situations of low speed vehicles in urban area. Three seniors include pedestrian crossing, stop in front of obstacle, and Stop and Go. The application of proposed intelligent Stop and Go system is possible for low speed driving assistance in urban area by our experimental results.
