Summary: A viscoelastic traffic flow model is developed to estimate travel time through a composite ring road, with numerical tests conducted to provide node traffic speed. It is found that ramp effects can impact traffic flow behavior, including causing congestion and traffic shock, while off ramp flow can shorten mean travel time and increase its value.

Summary: In this study, a mechanical device was designed to measure the relaxation modulus of viscoelastic materials by controlling a spherical indenter. The device was found to be accurate and easy to operate. The relaxation modulus function of the material was calculated by measuring the displacement and load of the indenter and fitting it using the non-negative least square method.

Summary: This paper proposes a hierarchical model for cooperative on-ramp merging control (CORMC) in mixed traffic. The upper-layer employs an anticipatory position searching (APS) algorithm and a collaborative utility choice (CUC) model to determine merging positions and assign cooperative vehicles. The lower-layer ensures safe and smooth merging execution with a cooperative merging control (CMC) model. Simulation results demonstrate the performance benefits of the CORMC model, particularly at higher compliance rates and CAV penetration rates.

Summary: This paper presents a three lane model to explore the effects of tunnel speed limit on traffic flow numerically. The model assumes that each lane has its own density and speed, and highlights the role of local homogeneity of traffic flow in expressing the lane-changing rate more simply. The simulation results show that a higher tunnel speed limit leads to a larger density threshold of traffic shock formation, but a shorter mean travel time and tunnel mean travel time.

Summary: This paper explores the impact of speed limit in freeway tunnels on car driving behaviors. A double lane traffic model is proposed to investigate the tunnel effect on travel time. The results indicate that while the tunnel significantly affects traffic flow patterns, its impact on travel time is minimal. On/off ramp flows play a crucial role in shaping traffic patterns.
