Automatic response to lane-blocking incidents is a critical issue in the field of automated highway systems (AHS). Accordingly, this paper presents a microscopic vehicular control methodology for automatic-control (AC) vehicular movements in response to lane-blocking incidents in the AHS environment. The embedded traffic control logic is based on the basic safety requirements for automatic-cont...

In order to alleviate the influence of low-speed vehicles on tunnel safety, this paper discusses setting method variable lane boundaries in urban tunnels. VISSIM simulation software is used analyze traffic flow when changes are allowed and prohibited. The results show that average speed tunnels greatest, can be significantly alleviated dividing line. When 40 km/h set, delay time reduced by 30–5...

This paper focuses on modeling mixed traffic flow that comprises human-driven vehicles (HV), adaptive cruise control (ACC) vehicles, and cooperative (CACC) in the off-ramp diverging area. The car-following behaviors of HVs, ACC CACC are modeled using an intelligent driver model (IDM), model, respectively. lane-changing different types areas anticipatory lane change (ALC) mandatory (MLC) model. ...

The microscopic simulation of traffic operations at a toll plaza entails the detailed understanding of the driver behavior. The lane selection behavior of the driver involves complex inter-vehicle dynamics. This study involves the development of a new methodology for the microscopic simulation of toll plaza operations. Different driver dynamics such as the lane selection probability based on th...

By the end of 2014, the total mileages of freeway in China have reached 112,000 kilometers, ranking the first in the world. Most of freeways are four-lane or six-lane, for which inside shoulder is not required by current Chinese guidelines. The inside shoulder is designed to reduce the possibility of fatal traffic accidents on freeways. In China, “Technical Standard of Highway Engineering” regu...

This paper introduces a multi-lane hybrid theory that treats lane-changing as temporary blockages, because this is what is physically observed in reality. For maximum accuracy lanechanging vehicles are modeled as discrete particles endowed with limited acceleration capabilities that interact realistically with the multi-lane continuum stream. This discrete-continuum (hybrid) setup is parsimonio...

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 ...

In this study, we propose a lane-changing conflict management model based on game theory for automated vehicles. When vehicle plans to change the adjacent lane, and if there is closely following that must sacrifice its speed make space vehicle, which means are conflicts of interest between two So far, no clear answer should vehicle. These individualistic models may lead suboptimal traffic flow ...

The AHS architecture of the California PATH program organizes traffic into platoons of closely spaced vehicles. A large relative motion between platoons can increase the risk of high relative velocity collisions. This is particularly true whenever platoons are formed or broken up by the join and split control maneuvers and by the decelerate to change lane control maneuver, which allows a platoo...
