Comparison of optimization methods for traffic semaphore crossroad on open road network

摘要

In this dissertation I'm introducing a program ARosem, with witch a optimal range of a green wave can be determined. I’m comparing it with a calculation of linear programming with an Excel and with a program Synchro. I also describe in detail how the program operates.udFor the comparison between programs I choose two road systems; the main street through the town Šentjur, named Ulica Dušana Kvedra, wich is quite simple road system, because it only has three crossroads with semaphores, and the most burdened road through the city Celje, named Mariborska ulica, that continues in Aškerceva ulica. This road system has 14 crossroads with semaphores in the distance of 3130 meters. Because of its complexity and the needs of the program I have split the problem on three parts that I joint at an end. I optimized these two road systems with the program ARosem and compared results for the same system with results, given by linear programming with Excel and program Synchro.udWith the comparison of the results I have determined, that the program ARosem is more appropriate for resolving smaller systems of crossroads with semaphores, since resolving larger road systems would require additional program upgrade, like adding vehicle acceleration and deceleration times into the equation.
