The construction of bus operation cycle

This paper is involved in the construction of bus operation cycle, through the vehicle test on road to gain the data of bus practical operation mode, using statistical analysis in data processing to construct the operation cycle, and analyze the cycle characteristics. Through the analysis of bus operation characteristics, firstly it was found there were 4 big category modes, namely the idle, constant speed, acceleration and deceleration. Then according to the speed interval of 10 km/h and the acceleration interval of 0.5m/s(2), each big category mode including of constant speed, acceleration and deceleration can be divided into small interval modes. Finally, bus operation cycle was constructed, which has 4 big category modes,78 small interval modes. The idle time of the operation cycle constructed constitutes 23.03%, the acceleration time and deceleration time constitute 73.64%, the constant speed time constitutes a little. The average speed is 22.7km/h. The characteristics of bus operation cycle above fits the bus operation rule. The operation cycle modes constructed mainly concentrate on the idle and (20-50) km/h, and acceleration and deceleration range from -1.0 m/s(2) to 1.0m/s(2).
