a r t i c l e i n f o A bi-level decision support system (BDSS) is proposed for a normative road network design with uncertain travel demand. A bi-level decision support model with link capacity expansion is developed to simultaneously reduce travel delay to road users and mitigate vulnerability of road network. A tractable solution scheme for BDSS is developed. Due to some hierarchy in decisio...

This study proposes a total secondary safety index for light passenger vehicles that rates the relative performance of vehicles in protecting both their own occupants and other road users in the full range of real world crash circumstances. The index estimates the risk of death or serious injury to key road users in crashes involving light passenger vehicles across the full range of crash types...

A major deficiency in state-of-the-art automatic speech recognition (ASR) systems is the lack of robustness in additive and convolutional noise. The model of auditory perception (PEMO), developed by Dau et al. (1996a) for psychoacoustical purposes, partly overcomes these difficulties when used as a front end for automatic speech recognition. To further improve the performance of this auditory-b...

In this section, we briefly present the formalism we use. This formalism aims at describing the state of a system and its dynamic behaviour in an algebraic framework [DG 94]. It was first introduced in a case study on a formal specification of the embedded safety part of an automatic subway pilot [DM 91], [Dau 92], [DGM 93], in order to cope with the large number of variables whose values made ...

The income from toll tariff is the main source of revenue to repayment investment costs road construction. estimated value tariffs can be usefull for regulators, investors and BUJT consider decision KPBU, company management. aim this study conduct a financial analysis rates Becakayu Toll Road. research method used Quantitative Method, by calculating ATP, WTP, perceptions applicable analyzing se...

Pekanbaru - Dumai toll road is one of the segments Trans Sumatra roads built by PT Hutama Karya. The connects economic centers in Riau Province, including Dumai-Duri-Kandis-Petapahan-Minas-Pekanbaru. On Pekanbaru-Dumai road, problems with service quality were found. This research has two objectives: to analyze and level satisfaction users assessed from users. second objective formulate referral...

BACKGROUND In Vietnam, the number of road traffic accidents increased dramatically which is a major threat for the national health system. Reliable data on the magnitude of traffic accidents as well as the current management of victims is missing. Our multistep international cooperation project aims to (1) identify local needs and knowledge related to trauma management, to (2) assess basic beha...

Many studies in the context of traffic simulation investigate effects of new regulation strategies on travel times. However, in most cases it is assumed, that these regulations are followed by all actors. This work investigates the effects of non-compliance of simulated road user agents. In particular it is analyzed to what extent rule breaking agents have advantages on the cost of the remainin...

In this paper we present and review a framework for online simulations and predictions which are based on the combination of real-world traffic data and a multi-agent traffic flow model. The agent architecture consists of two layers which distinguish the different tasks that road users have to perform. The framework is applied to the urban road network of Duisburg and the freeway network of Nor...

In this paper, the impact of endogenous information provision to drivers in road transport is investigated. A static economic equilibrium model is used, which allows potential road users to buy information on the prevailing (stochastic) traffic situation. It takes for granted that an indiviual will try to acquire proper information when the private benefits of doing so exceed the private costs....
