The passengers who was waiting at the site could observe operating conditions through the LCD of the bus stops ，in order that the passengers would make the most rational choice, saving time to facilitate travel.Transit Company Dispatch Center would schedule bus trips according to passenger flow conditions ，in that way could help conserve resources and satisfy transport needs.

Radiating portion is used in the bus to achieve people counting,to get the current speed and location by GPS,and send the information to the receiving portion, receiving portion shows the message by LCD to allow the passenger to choose the best way,the overall block diagram show as Figure 1. Figure 1.the overall block diagram 2 ACHIEVEMENT AND ARRANGEMENT OF PARTS 2.1 radiating circuit module： Radiating circuit module includes MSP430F169 PCB，GPS module,radiating circuit and double red
