Lack of infrastructure capacity to the demand in mobility results delays traffic. U-turns restrict movement opposing through-traffic during maneuver, hence triggering delays. Significant can be observed, especially high volume traffic, where U-turning is not restricted. Hence, it imperative study incurred by vehicles assess their impacts on traffic congestion. This thus proposes a quantitative ...

With advantages of less land use and better protection for urban landscapes, the underground expressway has become a new solution for urban traffic problems. Relevant safety studies are deficient despite of their significance in urban road networks. The differences between expressways on and under the ground made it inappropriate to apply the detailed design of the former directly or mechanical...

To deal with the conflicts between left-turn and through traffic streams and increase the discharge capacity, this paper addresses the pre-signal which is implemented at a signalized intersection. Such an intersection with pre-signal is termed as a tandem intersection. For the tandem intersection, phase swap sorting strategy is deemed as the most effective phasing scheme in view of some exclusi...

in this paper, an interactive model for individual normal behaviour of drivers is presented in which the mutual effect of vehicles has been incorporated. temporal features obtained from vehicles tracking and their motion history is utilized for generating a model of normal behaviour. because of non-stationarity of behaviour, hidden markov model has been used for interactive model. this model ha...

A number of operational and geometric factors impact the safety of at-grade intersections. Examples include the type of traffic control, the existence of left-turn lanes, and adequate sight distance. Determining whether an intersection of particular geometric design has unusual crash patterns could help identify those locations that need additional safety evaluation. During the last two years, ...
