With the capability of communicating with surrounding vehicles and infrastructures, connected automated (CAVs) can safely drive closer reduced headway, thereby potentially improving traffic efficiency. However, their superiority is compromised in mixed environment because interruption human-driving (HDVs). In this circumstance, researchers proposed to physically separate CAVs HDVs by deploying CAV-dedicated lanes (CAV-DLs). Nevertheless, CAV-DLs may be underutilized, especially low CAV...
This study focuses on the dynamic route control (DRC) problem for connected and automated vehicles (CAVs). The is usually solved using two popular methods, i.e., shortest path (DSP) system optimal assignment (DSO). However, DSP algorithm unproductive under congested conditions, while DSO, although can achieve optimal, possesses considerable complexity. Furthermore, methods are in a centralized due to need global information of entire network, which both communicationally computationally...
Pushbutton control is ideal for midblock crossings with low pedestrian and vehicle demand, but it causes significant interruptions to traffic flow frequent crossing requests. Therefore, we propose an adaptive (AMCC) that minimizes the impact of pushbutton on while maintaining a reasonably short wait time (PWT). We regard two adjacent intersections as integrated system types AMCCs—AMCC-band AMCC-vehicle—based different real-time information. AMCC-band seeks best PWT at minimize green band...
Connectivity analysis in vehicular ad-hoc networks plays an important role the research of intelligent vehicle infrastructure cooperative systems. However, some condition, connectivity VANETs can be deadly spoilt by unstable wireless performance, and sometimes packet loss rate between car to communication reach a considerably high percentage. Thus, hypothesis fixed transmission range is no longer appropriate for accurate analysis. In this paper, generalized model introduced stead using value...
Work zones, being a critical component of roadway transportation systems, can benefit greatly from computer vision-enabled infrastructures, specifically in connected vehicle (CV) environments. Connected such as roadside units (RSU) and on-board (OBU), improve the environmental awareness safety CVs driving through work zone. The contribution this paper lies developing vision-based approach to generate zone messages real time, utilizing video streams monocular traffic cameras that be used by...
Driving at velocity much lower than the speed limit greatly restraints movements of followers, resulting in considerable waste road resource every day. When two slow vehicles are moving abreast on city road, result is devastating for their followers. To solve such problem by idea i-Vics (intelligent vehicular infrastructure cooperative systems), this paper proposes a dedicated on-road traffic management plan low connected vehicles, especially scenarios near signalized intersections. The...
Urban transportation inefficiency at signalized intersections has been a complicate problem for decades and speed guidance is classic widely used method traffic optimization intersections. With the emergence of vehicular networks intelligent infrastructure cooperative systems, frequent information communication can be established between all units precise notification will available to help participants make better decisions. In this paper, we proposed model based on from most simplicity...
