BACKGROUND The purpose of this study is to increase our understanding of environmental correlates that are associated with route choice during active transportation to school (ATS) by comparing characteristics of actual walking and cycling routes between home and school with the shortest possible route to school. METHODS Children (n = 184; 86 boys, 98 girls; age range: 8-12 years) from seven ...

This paper explores some of the traffic phenomena that arise when drivers have to navigate a network in which queues back up past diverge intersections. If a diverge provides two alternative routes to the same destination and the shorter route has a bottleneck that generates a queue, one would expect that queue to stabilize at an equilibrium level where the travel time on both routes is roughly...

Linear referencing represents locations along routes, linear features with an established measurement system, using relative positions. It allows locating events along routes without segmenting it, and has been applied to manage linear features in transportation and utility. In transportation, dynamics in variant attributes such as speed limit, number of lanes, surface material, and traffic acc...

We propose a framework for management of route information and provision of travel information in the context of public transportation systems. The information-management component combines information collected from diverse sources, and processes the information for the interests of service providers and travelers. Travelers may place queries via different types of devices and interfaces, and ...

Wireless Sensor Networks in VANETs and how they have to exchange the traffic information among vehicles in order to achieve seamless service extensions due to unpredictable requests and broadcast chains in the network. To function this there are two possible approaches the push model and other is pull model. The goal of the data push communication model is to exchange information about the posi...

Transfer pattern routing is a state-of-the-art speed-up technique for finding optimal paths which minimize multiple cost criteria in public transportation networks. It precomputes sequences of transfer stations along optimal paths. At query time, the optimal paths are searched among the stored transfer patterns, which allows for very fast response times even on very large networks. On the other...

Nowadays, the development of „smart cities‟ with a high level of quality of life is becoming a prior challenge to be addressed. In this framework, promoting the model shift towards more reliable, greener and in general more sustainable transportation modes, namely towards a „smart mobility‟ could significantly contribute to achieve this goal. The aim of this paper is to provide users with more ...

Optimal routing is an important part of the methanol road transportation research. Optimal routing of methanol is different from those general optimal routing processes. Methanol optimal routing need to take into account the risk of path, the possible consequences of the accident and emergency response capabilities around the path and other factors This paper includes two aspects of research, o...
