A method for offset optimisation in signal controlled road networks

Despite the fact that manual optimisation approaches represent good engineering practice, their performance is restricted due to complexity of the problem. However numerical methods suffer from complexity of the NP-hard optimisation problem which is discrete in time and space. Therefore, this study presents a new offset optimisation method employing the Cell Transmission Model, which is a 1st order discrete traffic flow model. The proposed method further particularly cares about optimisation strategies and the respective running time requirements. In this context an optimisation algorithm based on genetic algorithm is developed, which uses a decomposition of the problem. For the covering abstract see ITRD E140665.
