What is a tidal lane?
2 Answers
Tidal lanes, also known as reversible lanes, are variable lanes set up on certain roads with one or more lanes that change direction based on the varying traffic flow during morning and evening rush hours. The direction of these lanes is controlled by lane signal lights to adjust the number of lanes available for traffic. The function of tidal lanes and the introduction of remote-controlled directional lanes are as follows: Function of tidal lanes: By changing the direction indicated by lane signal lights, the direction of main road lanes is controlled to adjust the number of lanes, thereby improving lane utilization efficiency. For example, during the morning rush hour when there is heavier traffic from the suburbs into the city, the number of inbound lanes can be increased while reducing outbound lanes to alleviate traffic congestion and improve flow. Conversely, during the evening rush hour, the lane configuration can be reversed to facilitate smoother outbound traffic. Remote-controlled directional lanes: Traffic police can manually adjust the direction of these lanes using remote controls to change the directional lane signs as needed, depending on real-time road conditions.
I drive through a tidal lane every day on my way to work, which is really convenient. This lane changes direction according to traffic peaks. For example, during the morning rush hour when more people are heading into the city, additional inbound lanes are opened, and in the evening when more vehicles are leaving the city, it switches to the outbound direction. This avoids traffic jams. Using it has saved me a lot of time. Previously, during peak hours, it would take half an hour, but now it only takes 10 minutes. The core mechanism involves indicator lights or movable barriers, so drivers need to pay attention to roadside signals and not follow the wrong lane. This design is common on urban main roads, with cities like Beijing and Shanghai adopting it because it maximizes road resources and reduces exhaust emissions. I think promoting tidal lanes can benefit more people, especially time-pressed commuters, as it is both eco-friendly and practical.
