In the bus network problem, the goal is to generate a plan for getting from point X to point Y within a city using buses in the smallest expected time. Because bus arrival times are not determined by a xed schedule but instead may be random, the problem requires more than standard shortest path techniques. In recent work, Datar and Ranade provide algorithms in the case where bus arrivals are as...

In the last decades, due to the increasing car traffic and the limited capacity of urban networks, algorithms for traffic management and route guidance are becoming more and more important. GPS technology can be used for fleet monitoring in urban or suburban areas, from a central monitoring station and may provide useful information concerning the movement of all vehicles. Current route guidanc...

This paper studies the dynamics of the traveler’s day-to-day route adjustment process in the general transportation network with fixed or elastic demand and homogeneous or heterogeneous users. Each traveler is assumed to adjust his/her route choice according to the excess travel cost between the instantaneous experienced travel cost and a certain referred level, which induces an aggregate path ...

To fix ideas, we can think of the graph as a public transportation network, where each edge represents a bus route connecting two stations. The n players can be thought of as employees that want to commute from their home stations si to a company located at station t. Assume that the operation of each route requires a fixed amount of money, say one unit of cost, which people using that route ca...

The consequences of a hazmat accident can be catastrophic due to the characteristics hazardous materials. Different from models, which are constructed perspective “government-carrier”, this paper considers three objectives risk, cost, and compensation cost “government-carrier-public” perspective, so as construct route optimization model transportation considering risk equity. Moreover, that dif...

This paper presents design methods for a flexible-route transit system, in which vehicles travel within predetermined areas to provide door-to-door service. The main advantage of this system is that passengers no longer have access stations order gain suitable low and heterogeneous passenger demand distribution as it features hybrid layout includes both hub-and-spoke network the peripheral regi...

Technology progress is a cause of industrial hazardous wastes increasing in the whole world . Management of hazardous waste is a significant issue due to the imposed risk on environment and human life. This risk can be a result of location of undesirable facilities and also routing hazardous waste. In this paper a biobjective mixed integer programing model for location-routing industrial hazard...
