There is a 3 km underground tunnel into which vehicles can either go or come one time because there is only one track. That is why two lights were given at each entry point so that the driver would know that he has to enter. If the signal is red he will stop and if it is green he will enter the tunnel I do not understand how to develop such a system.
I found on internet RFID technology can be use, each vehicle will have a unique tag that the reader will scan and send data to control room
Take a look at attached documents
I would appreciate your further thoughts on this
