Question: Like most people I travel everyday for work and I know that construction season is upon us. Can you write about getting people to understand the zipper merge? I still see a lot of people that can’t seem to figure this out.
Answer: The zipper merge is a driving strategy that requires drivers to change their mindset about merging. Traditionally, drivers have been taught to merge early when a lane is ending. Early merging leads to longer backups, more crashes and road rage incidents.
Zipper merge procedure
- When you see the “lane closed ahead” sign and traffic is backing up, stay in your current lane until the point of merge.
- Take turns with other drivers to safely and smoothly merge into the remaining lane.
- When traffic is heavy and slow, it is safer to remain in your current lane until the point where traffic can take turns merging orderly.
Benefits of the zipper merge
- Reduces the difference in speeds between two lanes, making lane changes easier and safer.
- Reduces the overall length of traffic backups by up to 40 percent.
- Reduces congestion at freeway interchanges, especially in metropolitan areas.
- Creates a sense of fairness when all lanes are moving at the same speed.
- Reduces incidents of road rage.
