Removing Traffic Jams with No-crossing U-turn

This no-crossing U-turns can replace Traffic Lights at junctions. You need two NCUT for each junction. You replace crossings with mergings. Accidents at crossings even with traffic lights were proven to be more fatal than accidents at mergings.

Removing Traffic Lights within City Centre of Kota Kinabalu

You can remove traffic light within the city, and do not allow right crossing. Only left crossings. No need to convert all roads into one-way streets. However, you need to create two no-crossing U-turns by converting roads around buildings at the edges of the city centre into one-way streets. These U-turns are required to do the right turns. Of course, roads not covered by the U-turns, will not be able to do right turns.

Second Responses to Smarter Transport

Thank again. Your responses are more reasonable this time but I would like you to consider a few assumptions that you make. These assumptions are what make the proposals in the study not effective. Please refer to my comments alongside your statements, and my previous statements, below. Yours sincerely, Saya yang menjalankan amanah. (I, who executes the trust) Ir. Hj. Othman bin Hj.

Traffic lights cause jams

Traffic lights cause jams. They worsen congestion by reducing lane capacity by half. This causes more congestion instead of relieving the congestion. When no congestion, lane Capacity is full, but with more traffic, the lights reduce them to half, making the congestion worse, so causing jams. I wonder why ignored by planners. Not even in textbooks the subject of congestion. Even journals never have a consistent definition of congestion. For drivers, cars not moving is called traffic jam. Not to the civil Engineers because at Traffic lights, cars do not move also. The solution is simple. Remove all traffic lights but forbid right turns. To turn right, you must do U-turns. Not difficult in cities because there are lots of buildings. These buildings are huge roundabouts. One other solution is one-way street. It was proposed by a consultant 10 years ago. Dr. Tan. I didn't support but now I understand why.
