How gaps are created during anticipation of lane changes

Kequan Chen et al.

Summary: This study investigates the impact of anticipation on the behavior of a new follower (NF) in a target lane using new trajectory datasets. The results show that anticipation significantly affects the NF's movement, resulting in gap creation and speed reduction. The developed binary logistic models can predict the NF's behavior with good performance.

Freeway tunnel effect of travel time based-on a double lane traffic model

Yongliang Zhang et al.

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.

Integrated mainline and ramp signal control for expressway on-ramp bottleneck with unequal lane-setting

Xiaoyun Chen et al.

Summary: Ramp metering is a major measure to reduce traffic congestion and prevent breakdowns, but its efficiency can be limited by traffic demands. A novel control strategy, T-MRC, was proposed for unequal lane-setting on-ramp bottlenecks to maximize traffic efficiency, resulting in significant improvements in productivity and vehicle total delay.

Lane Change Control Combined with Ramp Metering: A Strategy to Manage Delays at On-Ramp Merging Sections

Hari Hara Sharan Nagalur Subraveti et al.

Summary: This paper introduces a control strategy combining lane change control with ramp metering system at motorway merges. Results show that this combined control strategy can reduce total travel time significantly and regulate the delay distribution between the mainline and on-ramp traffic effectively.

Variable speed limit strategy with anticipatory lane changing decisions

Bidoura Khondaker et al.

Summary: This paper develops a novel anticipatory Variable Speed Limit (VSL) control strategy that incorporates driver behavior based on trajectory data from probe vehicles. The study aims to optimize speed limit controls to reduce lane changing and braking, thus improving traffic throughput, safety, and sustainability. Results show that the VSL strategy can lead to decreased lane changing rate and smoother acceleration and deceleration patterns, resulting in lower emissions and fuel consumption.

Ramp metering control under stochastic capacity in a connected environment: A dynamic bargaining game theory approach

Seiran Heshami et al.

Summary: This study introduces a dynamic predictive and cooperative ramp metering method that takes stochastic breakdowns at merging bottlenecks into consideration. It uses a stochastic microscopic model to estimate traffic state parameters and models the ramp metering problem as a stochastic distributed model predictive control (SDMPC) approach solved through a game method.
