Xx CGI traffic control and xxcgi Traffic ControlTraffic control is divided into two steps. First, the user's ip address is restricted in the CGI framework, and second, the traffic of each CGI is restricted. 1.

Traffic light Management system Simulation to achieve the intersection of traffic lights management system logic, the specific requirements are as follows: Ø randomly generated vehicles that follow each route. For example: Vehicles coming from the south to the north----straight vehicles. Vehicles from the west to the south----turn right Vehicles from east to south----left-turn vehicles 。。。 The signal light
