D.A.F.C Posted June 20, 2019 Share Posted June 20, 2019 When queuing on the slip road to join a slow-moving motorway, you'll always get some clowns who bomb past the queue down to the very end of the slip road to try and barge their way in. I cannot overstate the burning animosity I feel towards these sentient scrotums.BMW or Audi drivers imo. 0 Quote Link to comment Share on other sites More sharing options...

It is folk who queue up who cause things to slow down. This theory is an urban myth. Imagine two queues waiting to enter one turnstile. Whatever order the individuals enter the turnstile the rate of progress will be exactly the same... 1 Quote Link to comment Share on other sites More sharing options...

A dual carriage slipway has two moving turnstyles to join, if everyone stays in the same lane there's only one. 0 Quote Link to comment Share on other sites More sharing options...

As pointed out earlier, the rate of progress through the bottleneck is identical. Except when some knobend tries to force their way in at the last minute, causing traffic to bunch up and slow down. 0 Quote Link to comment Share on other sites More sharing options...

Exactly. The rate through the turnstile doesn't change but the queue jumpers get through quicker. 0 Quote Link to comment Share on other sites More sharing options...

They ran a test in one of the tube stations in that there Londonium ( I think it might have been Bond Street) where the stopped people going up the left side while folks stand still on the right , instead they made 2 folk stand side by side on each step. The total traffic throughput went up about 20% per hour. but when not being “enforced” the cn**s who are entitled to go faster effed the system up for everybody else because they deserve to get wherever , faster 0 Quote Link to comment Share on other sites More sharing options...

If you have two cars sitting one sitting in each lane at the bottleneck then they will obviously get through it quicker than one car behind the other. Simply put the distance to travel to the other side of the bottleneck is less. Edited June 21, 2019 by strichener 0 Quote Link to comment Share on other sites More sharing options...

Car in RH lane has to cross from one lane to the other then go in a straight line - even if we're just talking a few metres, it's a longer distance. Add in the embuggerance of those in the LH lane having to stop and start repeatedly instead of driving smoothly it's clear that one lane of traffic driving in a straight line uses the least energy. 0 Quote Link to comment Share on other sites More sharing options...

So, if you joined the end of the 4-mile tailback it would take you the same length of time to get through the bottleneck as if you had joined the end of either of the 2-mile tailbacks? Seems unlikely but I can understand the concept 0 Quote Link to comment Share on other sites More sharing options...

That is just wrong. A car sitting parallel to the another car at the bottleneck will have significantly less distance to travel to the bottleneck than a car sitting behind. You are ignoring the fact that where there is only a single queue of traffic, car 2 has to travel the length of car 1 + any gap to reach the bottleneck. 0 Quote Link to comment Share on other sites More sharing options...

You're forgetting that the car in the RH lane has already travelled the length of the car in the LH lane. Shortest distance between two points is a straight line. 0 Quote Link to comment Share on other sites More sharing options...
