Sure. But now you have to spend more money on adding lanes for the same traffic capacity because the average speed drops.

- adrianN 2y agoRoad capacity usually increases as speed goes down.
- sliken 2y agoCars per mile, yes. Cars per second no. If you follow the recommended 3 second spacing then it's a car per 3 seconds per lane. So for a fixed distance, the slower you go, the longer you are on the road, the more road capacity you consume.
- adrianN 2y agoTraffic flow is more stable at lower speeds, so you get less congestion.
