>>1921565>Where are all the cars in 1980? According to the theories /n/ likes to repeat that highway should be packed full of cars.the highway in that picture is the catharijnebaan in utrecht, now known as the catharijnesingel canal again. they only ended up building a small part of the proposed canal ring road due to resistance from locals, meaning that it was an extremely short highway basically leading nowhere. as such it's not subject to induced demand, since roads leading nowhere obviously won't see intensive use.
>No wonder changing the Cheongyykan highway or whatever it was called back into a creek had no real effect on traffic flow.the cheonggyecheon highway on the other hand is a great example of reduced demand, the highways was absolutely chock full of traffic but after the removal the traffic disaster people predicted never materialised, as people simply started driving less and there were plenty of other transport options available. it's a good reminder that there is no static amount of car traffic, most trips simply are not neccessary at all, and deliveries and other needed trips will be better off not being stuck in traffic surrounded by personal vehicles.
