Abstract
In this study, a Discrete Particle Swarm Optimization (DPSO) algorithm is assimilated to solve the Transit Network Design Problem (TNDP). First, A Mixed Integer Model is developed for the TNDP. The solution methodology utilized here is made of two major elements. A route generation module is firstly developed to generate all the feasible transit lines. Through the second part, a DPSO algorithm is utilized to select the optimal set of lines from the constructed ones. The objective function is to maximize coverage index while satisfying the operator cost upper level constraints. The efficacy and accuracy of the implemented algorithms is compared with ones obtained by an enumeration process as...

Abstract
The Population Growth, Land-use Development and the Increase in Vehicle Ownership in big cities have caused an increase in Travel Demand and the volume of vehicles passing through Urban Routes. Travel Time in the urban route network due to increase in congestion in one of the most important problems in Metropolises. A considerable part of Travel Time in the Metropolitan routes network is related to delay time in intersections. Thus, controlling methods for intersections in order to decrease such delays is of a great importance. The application of Fuzzy Logic as a control basis in engineering issues has a proper background. In this study, a method for controlling such signalized intersections...
