Anthropogenic noise associated with highway construction and operation can have individual- and population-level consequences for wildlife (e.g., reduced densities, decreased reproductive success, behavioral changes). We used a before-after control-impact study design to examine the potential impacts of highway construction and traffic noise on endangered golden-cheeked warblers (Setophaga chry...

Most of the existing traffic control strategies implemented in many countries in the world tend to aim only at improving the efficiency of traffic output. However, decreased the delays and safer traffic are also important outcomes of traffic control. In this study, a dynamic algorithm for variable speed-limit control at toll booth zones is presented that can take full advantage of its dynamic f...

Intelligent vehicle platoon driving is a process of the flexible formation based on the coordination between vehicle and highway in the intelligent vehicle-highway system, which can increase the controllability of traffic, simplify the complexity of traffic control, and ease the traffic pressure. It has been constructed that the intelligent vehicle platoon driving simulation experiment system u...

short term prediction of traffic flow is one of the most essential elements of all proactive traffic control systems. although various methodologies have been applied to forecast traffic parameters, several researchers have showed that compared with the individual methods, hybrid methods provide more accurate results . these results made the hybrid tools and approaches a more common method for ...

Today’s, a common problem in cities is increasing delay and reducing the speed of traffic. On the other wise increasing costs of acquisition in urban area are not allow new routes and highways. Also construction of new highway or street such as Imam Ali highway and Sadr highway in Tehran lead to develop new applications (such as BRT lane ,…) And become quickly saturate and less eff...

Traffic congestion in highway networks is one of the main issues to be addressed by today’s traffic management schemes. Automation combined with the increasing market penetration of on-line communication, navigation, and advanced driver assistance systems will ultimately result in intelligent vehicle highway systems (IVHS) that distribute intelligence between roadside infrastructure and vehicle...

This paper is concerned with the traffic flow stability/instability induced by a particular adaptive cruise control (ACC) policy, known as the ‘‘constant time headway (CTH) policy’’. The control policy is analyzed for a circular highway using three different traffic models, namely a microscopic model, a spatially discrete model, and a spatially continuous model. It is shown that these three dif...
