An iterative algorithm to determine the dynamic user equilibrium with respect to link costs defined by a traffic simulation model is presented. Each driver's route choice is modelled by a discrete probability distribution which is used to select a route in the simulation. After each simulation run, the probability distribution is adapted to minimize the travel costs. Although the algorithm does...

Traffic signals are a very important instrument to manage urban traffic. When designing traffic signal programs, many different goals and road user needs have to be considered. While traffic engineers must ensure the technical planning, implementation and operation of traffic signals, their work must be supported by a clear policy. One of the major questions to be answered within such traffic s...

The continuous increases in the numbers of road traffic crashes (RTC) over years, especially developing countries, have been a source worry. majority RTC are attributed to user behaviours exhibited by drivers. This study sets out investigate attitudes and Abuja, Nigeria. A total 1526 questionnaires were distributed, which 321 completed returned. tried understand four major behaviours, namely us...

The paper examines the positive and the possible adverse effects of adaptive user interfaces (AUIs) in the context of an in-vehicle telematic system as a function of four factors: (1) four different levels of adaptivity (ranging from manual to fully adaptive with intermediate levels); (2) different tasks; (3) routine (familiar) and non-routine (unfamiliar) situations; and (4) different user age...

There is a strong imbalance in EU transport mode share. In addition issues like road congestion, noise, accident rate and especially pollutant emissions result not only in external costs to society but also in high logistical costs to customers of transport services. The present paper proposes an assessment model to evaluate final internal and external costs of transport chains served by road a...

This paper presents an approach for analysing and prototyping urban road network routes based on multiple criteria, such as spatial quality, transportation cost and aesthetics, in order to evaluate the quality of people’s use of road networks. A prototype is developed to analyse routes and accessibility in road layouts from a number of design and user related perspectives. A case study is used ...
