The existence of different types Commercial Vehicles (CVs) in the shared roadway affects traffic flow characteristics differently from other vehicles. Owing to uncertain placement and movement these CVs both longitudinal lateral directions, opportunities for lane changing overtaking by vehicles with lower maneuverability decrease, resulting formation platoons. study's primary aim is assess effe...

This paper proposes a fuzzy logic control based dynamic channel allocation (DCA) to ECMA-368 based WiMedia UWB networks, which aims to support mixed high-quality video traffic and shipboard control data traffic with high reliability and priority as well. The DCA method applied in this paper is to flexibly vary the portions of time slots of either the prioritized contention access (PCA) or the d...

Connected autonomous vehicles (CAV) technologies are about to be in the market in the near future. This requires transportation facilities ready to operate in a mixed traffic environment where a portion of vehicles are CAVs and the remaining are manual vehicles. Since CAVs are able to run with less spacing and headway compared with manual vehicles or mixed traffic, allocating a number of freewa...

Self-organizing traffic jams are known to occur in medium-to-high density traffic flows and it is suspected that ACC algorithms may affect their onset in mixed human-ACC traffic flows. Unfortunately, closed-form solutions that predict the statistical occurrence of these jams in mixed traffic do not exist. In this paper, a closed form solution that explains the impact of adaptive cruise control ...

BACKGROUND Pedestrian crossing is an important traffic safety concern. The aim of this paper is to report the protocol for a sequential explanatory mixed methods study that set out to determine the pedestrians' traffic behaviors, the associated factors and exploring the perception of young people about the traffic risky behaviors in crossing the road. The ultimate purpose of the study is to des...

Contraflow operation is frequently used for reducing traffic congestion near tunnels and bridges where traffic demands from the opposite directions vary periodically. In this work, a generic real-time optimal contraflow control method has been introduced. The introduced method integrates two important functional components: 1) an intelligent system with artificial neural network and fuzzy patte...

Managed lanes, such as a dedicated lane for connected and automated vehicles (CAVs), can provide not only technological accommodation but also desired market incentives road users to adopt CAVs in the near future. In this paper, we investigate traffic flow characteristics with two configurations of managed across different penetration rates quantify benefits from perspectives lane-level headway...
