Information technologies (IT) have been developed rapidly in the last decade of this century. Recently, the information technologies start combining with other technologies such as nano-technology, bio-technology and so on. Intelligent transportation systems (ITSs) is the one of the combined technologies which is convergence of transportation system and information technologies. ITS affect the first period of traffic, crossroad signal control is one of them. The existing crossroad signal control is divided into static signal control and actuated signal control. Static signal control and Actuated signal control have merits and demerits, but most signal control is study about actuated signal control. This Actuated signal control research was designed without considering heavy goods vehicles because of technical problem with vehicle information collection. Therefore, in this paper, we suggest CSCH(Crossroad Signal Control for Heavy goods vehicles) algorithm with the purpose of crossroad total vehicle flow increased and average vehicle waiting time reduced. The result shows that when adopting the CSCH algorithm, comparing to the existing signal control algorithm, the total vehicle flow increased and average vehicle waiting time decreased. Thus, we find that efficiency of traffic flow increased.
