This paper addresses a bi-modal multi-objective discrete urban road network design problem. The problem includes the simultaneous design of urban road and bus networks in urban areas in which the authorities play a major role in designing bus network topology. The road network design consists of decision making for lane additions to the existing streets, new street constructions, determining th...

Traffic injuries are predicted to be the fifth leading cause of death and injury by 2030 if no further action is taken. Generation Y, who are growing up with technology and Internet, are among the most vulnerable road users, so it is crucial to provide effective road safety training for them. In the light of the Uses and Gratification Theory (U&G), we propose a conceptual research model to meas...

Location information is of vital interest for emergency services throughout Europe. Among the recent priorities of the European Union is to promote appropriate electronic communication technologies (like mobile cellular networks and satellite location systems), in order to improve road safety, to speed up rescue times and to provide an efficient ‘harmonised’ European emergency call (eCall) serv...

This paper deals with two main problems in forest harvesting. The first is that of selecting the locations for the machinery to haul logs from the points where they are felled to the roadside. The second consists in designing the access road network connecting the existing road network with the points where machinery is installed. Their combination induces a very important and difficult problem...

One of the main challenges in developing efficient and effective winter road maintenance is to design an accurate prediction model for surface friction coefficient. A reliable coefficient can help decision support systems significantly increase traffic safety, while saving time cost. High dynamicity weather conditions lead presence uncertainties historical data extracted by sensors. To overcome...

Private road associations (PRAs) manage two thirds of the road network in Sweden. They manage the roads at less cost and with better results than the Government road agencies. In fact, the PRAs perform so well that some urban municipalities request the associations to manage the municipal roads which connect to the private roads. There are also PRAs that are responsible for ferry services, for ...
