This work has the purpose to develop a computational tool based on the concepts of Non-linear Programming and Voronoi Diagrams to study and define the ideal bus-stop spacing in urban areas in order to minimize the total travel time of all passengers until a common destination. The idea is to help the cities to organize their traffic in the central areas. The main problem these cities are facing nowadays is the high number of automobiles that are used by the people for private transportation. In order to reduce the number of vehicles in the streets, public administrations are trying to improve the public transportation system in order to stimulate people to leave their cars at home. One way to encourage people to do that is reducing the time the passenger spent to go to their destinations using public transportation. The model also will allow us to solve problems of regional division of the affected areas to each bus-stop determining the scope area of each one of them. The system uses the density function of the distribution of the population in the affected area and combines it with the model of the Additively Weighted Voronoi Diagram to search for the minimum value using the usual methods of non-linear programming.
