In the massive activities of cities, rush hour is short while traffic flow is great. Traffic flow is unbalanced on time and space. If the measure of traffic control is not right, the traffic is affected badly. In this paper, a bi-level programming model about traffic control measure is brought forward. In upper level, providing key member with high transportation service is first thought over, and...
In this paper, a bi-level programming model is presented to determine the optimal system performance for urban traffic network under the scenario that the drivers' parking and route choice behaviors with or without advanced transportation information system (ATIS) are considered. An extension of the successive average algorithm based sensitivity analysis method is proposed for solving the bi-level...
The link counts are usually inaccurate under the influence of measurement and sampling errors, all kinds of adventive events and succedent data processing errors. Ignoring data inaccurateness may lead to unacceptable error of O-D matrices estimation. To make the best of the fuzzy information acquired from traffic survey, this paper presents a bi-level programming model with fuzzy expected value model...
Transportation network design problem deals with how to add or improve some edges on an existing transportation network to improve traffic condition. In this study a bi-level programming model was proposed to optimize the strategy of transportation network capacity improvement in the constraint of budget. The upper level problem aims to minimize the total travel time of all transportation travelers,...
This paper combine the concept of reserve capacity with the continuous equilibrium network design problem, an integrated method is used to maximize the reserve capacity of a road network. On the one hand we try to find the maximum possible increase in traffic demand by setting traffic signals at individual intersections. On the other hand, we increase the road capacity in order to increase the whole...
Operation in a container terminal is a complex system with many inter-related decisions. In this paper, a bi-level programming model for container terminal scheduling is developed to improve the integration efficiency of container terminals. The model consists of two sub-models, the upper-level model is quay crane scheduling problem, and the lower-level one is dynamic trailer routing problem. The...
