Cellular vehicle-to-everything (C-V2X) is an emerging technology that has the potential to significantly improve traffic safety and efficiency through various applications such as pedestrian alerts, traffic hazard warnings, signal timing information broadcasting, etc. With the help of the Federal Communications Commission's agreement to waive restrictive rules on C-V2X deployment, extensive real-w...Show More
The large-scale application of connected automated vehicles (CAVs) provides new opportunities and challenges for the optimization and management of traffic conflict zones. To improve the traffic efficiency of conflict zones and reduce the travel delay and fuel consumption of CAVs, this paper presents a two-level optimization method of scheduling and trajectory planning for CAVs. At the first level...Show More
Most existing cellular probe-based freeway congestion detection methods rely on on-call WLT (Wireless Location Technologies) signal transition data. However, these techniques facing difficulties such as small sample size, frequent road tests, safety, and privacy issues. This article presents a novel approach using the FCA data for traffic congestion detection on freeways. Two cellular activity fea...Show More
Intersections are the key joint points on arterials in urban transportation networks. Congestions at intersection areas significantly degrade human travel efficiency. Therefore, analyzing congestion and exploring congestion detection technologies to mitigate intersection congestions is important for intelligent transportation systems. This paper proposed the space mean speed calculation method at ...Show More
Existing layouts of sensors on freeways usually have room for improvement. The optimal allocation of multi-type sensors could increase the accuracy and coverage of data acquisition for traffic control and management. This paper aims to explore the appropriate method to solve the multi-type sensor allocation problem on freeways. Two types of sensors, the micro-loop sensor and the microwave sensor, ...Show More
A new method based on phase-sensitive optical fiber sensing technology (Φ-OTDR) is presented in this paper. The method first uses Φ-OTDR to acquire the original signal of railway tracks vibration for a while, then conducts filtering, short-time Fourier transform and auto-regressive model spectrum estimation of the original signal, After analyzing the frequency signal feature, we can determine whet...Show More
