Recently, Cellular Automata (CA) models are developed and studied mostly for homogeneous traffic flow. In the current paper an attempt has been made to use CA models to study heterogeneous traffic flows which are common in real life situation. For a better representation of different types of vehicles, cell sizes have been reduced. A different set of CA rules to control the light and heavy vehi...

This paper evaluates strategies for operating buses on signal-controlled arterials using special lanes that are made intermittently available to general traffic. The advantage of special bus lanes, intermittent or dedicated, is that they free buses from traffic interference; the disadvantage is that they disrupt traffic. We find that intermittent lanes, unlike dedicated ones, do not significant...

The strategy of exempting bus from other traffic through exclusive bus lanes (XBL) is prevalent. Rather than just deploying the XBL system, in this study, a new innovative dynamic bus lane (DBL) operation system which is expected to be more productive is initially introduced. Unlike conventional studies which are mainly focused on operational performance of buses, this study attempts to examine...

Work zones have significant negative impacts resulting from reduced capacity and speed, and increased accidents and delay. Thus, it is important to design a traffic control strategy that has minimum potential impact on the traffic at the work zone and the traffic in its vicinity. In this study, a regional microscopic model is used to evaluate different control strategies at a work zone on inter...

This paper develops output feedback boundary control to mitigate traffic congestion of an unidirectional two-lane freeway segment. The macroscopic dynamics are described by the Aw–Rascle–Zhang (ARZ) model respectively for both fast and slow lanes. density velocity each two lanes governed coupled 2 × nonlinear hyperbolic partial differential equations (PDEs). Lane-changing interactions between l...

Purpose The study sought to estimate the effects of centreline milled rumble strips on rural two-lane roads in Sweden in a wide perspective. Traffic safety effects (i.e., fewer crashes and injuries), driver experience, and driver opinions of centreline milled rumble strip usage on rural roads are investigated. Methods To evaluate the traffic safety effects, an Empirical Bayes study comparing th...

Traffic safety is a major concern in the temporary one-lane, two-way highway work zones due to the increasing of construction and maintenance operations. To prevent rear-end crashes and to mitigate the severity of these crashes caused by the inattentive driving, the utilization of the Emergency Flasher Traffic Control Device (EFTCD) was under consideration by government agencies, in addition to...

Lane changing manoeuvres of heavy vehicles have significant influence on surrounding traffic characteristics due to the physical effects that the heavy vehicles impose on surrounding vehicles. These effects are the result of heavy vehicles’ length, size, weight and the limitations in their manoeuvrability. Due to the importance of heavy vehicle lane changing manoeuvres, this paper presents an e...
