Embodiment Construction

[0057] The calculation method of intelligent bus dispatching schedule of the present invention, firstly, establishes the mathematical model of genetic algorithm, secondly, uses the obtained mathematical model to design the specific solution steps of genetic algorithm, and the termination condition of the algorithm is when the genetic algebra Gen reaches the specified maximum genetic algebra. Specifically include the following steps:

[0058] Step 1. In order to simplify the difficulty of solving the problem, make the following idealized assumptions on the actual bus operation. The assumptions made are as follows:

[0059] Vehicles on the same line use the same model, no passengers are stranded after the bus passes by, the vehicle travels at a constant speed and the time of entering and leaving the station is fixed, the running time of each line is fixed, and the arrival of passengers is uniformly distributed.

[0060] Step 2. For the convenience of calculation, define the fol...
