Late Merge – Zipper Merge

Zipper merging is a new driving strategy that requires changing driver's thinking and this has traditionally been taught to merge in advance at the end of lane recognition. As a result of early integration, the backup will be lengthened, the crash will occur, and the load anger event will increase.

The next new driver is when the sign of "Front lane off" is displayed, the traffic is backed up and staying in the current lane until the junction. Then please turn and other drivers safely and smoothly into the remaining lane. If the traffic volume is high and the speed is slow, the driver can safely run the current lane until traffic volume regularly joins.

Reduce the speed difference between two lanes. If the lanes are running at nearly the same speed, lane change is easier and safer.

Since the car changes into a lane in the same way that zipper's teeth gather, the maneuver is called late merge, or zipper merge. In this work, experts will reduce traffic congestion and drivers' frustration by stopping at a lane where closely-crowded late cars are closed and then running a car to another lane at the confluence point It helps. Christie Erickson, a workspace engineer at the Kansas State Transportation Authority, said in an e-mail that "officials are often seeing significant differences in traffic speeds in the workplace (mostly within lanes, adjacent roads)." Speed) Lane and anger of road (rude gesture, resolution of gap, lane blocking)

The later merger, more nicknamed "merging of" zipper "nicknamedly, is when the driver fills two lanes and then merges once at the end of the lane. This one-time merger is under the name of "zipper". According to the survey, under crowded conditions this technology can reduce the free capacity by 40% to 70%, and by combining points the traffic will move better in general as the drivers cooperate to eliminate the gap. Strong injection of the channel. This is a sudden, accidental, especially mandatory merger from the standstill, causing a shock wave in the traffic flow, and as a result frequently seen stop-by conditions occur. When people change and know this is expectation, they can gradually open a gap while still moving. A driver in a closed lane can predict where to join, align, and merge smoothly without stopping. Essentially, it is equally informative for everyone.

When the traffic gets congested and slowly passes through the bottleneck, the zipper combines best. If traffic flows freely, early integration is the right approach. In this case it will help to merge as soon as possible to maintain free flow of traffic. As mentioned earlier, drivers waiting until the last minute often need to slow down or stop the merge. After that someone in the channel stops or decelerates them to merge them and then stops or decelerates the back person, which causes traffic congestion and rear collision. With early integration, drivers can find and enter traffic gaps and other drivers can fine-tune the interval to maintain traffic flow while maintaining speed.
