Solution method to a new model for real-time traffic signal timing

The solution method to a new model for real-time traffic signal timing is studied. The numerical ways to deal with the piecewise functions in the objective and to solve the equations with unknowns contained in the upper limit of an integral are designed. And then a genetic algorithm is presented for this model. In order to test the model and the algorithm, numerical simulations are performed. The numerical results show that the algorithm is effective and efficient.
