Dynamic Lane Merge System

OUR EQUIPMENT INTEGRATES TO:

Efficiently manage traffic approaching a lane closure when the demand exceeds the capacity by incorporating a Dynamic Lane Merge System. Positioned in advance of the taper, this system calms traffic and prevents collisions within highway work zones.

System Information

Depending on the type of sensor used, Street Smart can determine the following information from vehicles: speeds, volume, classification, gap, occupancy, headway, etc. This information creates advanced warning messages upstream, alerting the traffic of conditions ahead.

The changeable message sign provides real-time direction on lane usage and merging.

Deployment Criteria Considerations

These systems should be considered for deployment as part of a project’s temporary traffic-control plan when any of the following conditions are anticipated:

A high hourly traffic volume causes a queue of traffic before the merge area for at least two hours per day. Typically, this volume must exceed 1,500 vehicles per hour to cause large queues.
During congested periods when the estimated traffic queue lengths (without the DLM system implemented) may encroach on upstream intersection/interchange operations.
The speeds and lane occupancy volumes are anticipated to vary unpredictably causing the motorist to have trouble identifying the best lane-usage practice, such as using both lanes versus moving into the continuous thru-lane.

Anticipated System Effects

The dynamic lane merge system should alert drivers of an upcoming traffic slow-down or stopped traffic and inform them to use both lanes until the designated merge point. The system should reduce the length of the upstream queue by 40%, which may reduce conflicts at nearby intersections. Therefore, by utilizing both traffic lanes, the differential speed between lanes is significantly decreased since both lanes travel at approximately the same speed. Drivers recieve positive directions on lane usage and merging, which clears disagreements between drivers and reduces road rage.

MnDOT – Zipper Merge Traffic Camera Instructional

Minnesota DOT caught a great example of the Dynamic Lane Merge’s effectiveness.

Drivers frequently start to merge in construction zones as soon as they see warning signs. This driving behavior, called “early merge,” can lead to dangerous lane switching, inconsistent driving speeds that cause crashes, long back-ups that block interchanges, and road rage.
