After a brief review of the theoretical principles of road pricing this paper presents the results of a modelling exercise aimed at ascertaining the effects of road pricing on a large road network. For the study area we chose an important part of the road network of Belgium, situated in the corridor between the main cities of Brussels and Ghent. Simulations were carried out using an elastic static traffic assignment method. Special care was ...

Urban population growth and economic development have led to the creation of new communities, jobs and services at places where the existing road network might not cover or efficiently handle traffic. This generates isolated pockets of areas which are difficult to reach through the transport system. To address this accessibility problem, we have developed a novel approach to systematically examine the current urban land use and road network ...

This paper proposes a method for inferring the road network from Global Position System (GPS) traces, which is composed of intersections and the roads between each pair of directly-connected intersections. Random Sampling (RANSAC) algorithm is used to cluster the turning points, where the users change their moving directions, into intersections. All of the GPS traces are segmented by the intersections, resulting in connectivity matrix of the ...

In this paper we consider the problem of allocating resources to upgrade a rural road network in order to improve the accessibility of as many people as possible to the main cities or regional center where the economic and social infrastructure is usually located. We propose a solution approach based on the GRASP and VNS Metaheuristic. The efficiency of our approach is demonstrated on a set of random small and medium size instances and on a ...
