[ 1 ] - A Novel Model for Bus Stop Location Appropriate for Public Transit Network Design: The Case of Central Business Districts (CBD) of Tehran

In this paper, a novel multi-objective bus stop location model is proposed, which considers not only the coverage of demand and minimization of access time but also the necessities of suitable stops for transit network design phase. Three objective functions are considered including minimizing (I) sum of the total access distance (time), (II) the weighted combination of stops, and (III) the num...

[ 2 ] - Predicting the Next State of Traffic by Data Mining Classification Techniques

Traffic prediction systems can play an essential role in intelligent transportation systems (ITS). Prediction and patterns comprehensibility of traffic characteristic parameters such as average speed, flow, and travel time could be beneficiary both in advanced traveler information systems (ATIS) and in ITS traffic control systems. However, due to their complex nonlinear patterns, these systems ...

[ 3 ] - الگوریتم ترکیبی موثر ژنتیک برای حل مساله مسیریابی وسیله نقلیه

  The Vehicle Routing Problem (VRP) is one of the most important combinational optimization problems that has nowadays received much attention of researchers and scientists. In this problem, the objective is to minimize the cost traveled by several vehicles that start to move simultaneously from depot and come back to depot after visiting customers if at first each node is visited only once by ...
