Synthesis of Unconventional Dynamic Merge Metering Traffic Control for Work Zones

This paper presents an unconventional approach for work-zone bottleneck traffic control through integrating the dynamic late merge with a merge metering via wireless communication at the downstream taper area of a work zone, termed as Dynamic Merge Metering Traffic Control System (DMM-Tracs). The architecture and communication system for the DMM-Tracs, including system components, communication...

Development and Evaluation of the Lane Merge Traffic Control System at Construction Work Zones

Effectiveness of temporary traffic control measures in highway work zones

In the United States, hundreds of people lose their lives each year and many more are injured due to vehicle crashes in the work zones. Over the years, temporary traffic control (TCC) measures have been developed and deployed in work zones. To continuously improve the safety, there is a need to identify the traffic control deficiencies in work zones by evaluating the effectiveness of existing T...

Control of traffic with anticipative ramp metering

When there are different routes from origin to destination in a network, the traffic divides itself over these routes. The resulting assignment is often determined by the travel times on the different routes. When control measures are implemented the travel times for some routes change, which can lead to a change in the assignment. This change in assignment can effect the performance of the who...

Case Study of an Alternative Merging Sign Design for Temporary Traffic 1 Control in Work Zones

21 Signage plays an important role in work zones to provide guidance to drivers under changed 22 conditions. This study investigated the safety effect of an alternative merge sign configuration in 23 a freeway work zone. In this alternative configuration, the graphical-only lane closed sign from 24 the Manual on Uniform Traffic Control Devices (MUTCD) was compared against a 25 MERGE/arrow sign ...
