A traffic jam is a problem with the flow of traffic on a road cause by all cars stopping momentarily or for a long period of time. It is similar to slug flow in piping systems when laminate flow turns to turbulent flow. It is caused by accidents, weather conditions leading to road hazards, poor driving skills, poor coordination of traffic lights, or the poor design of merges and other intersections. It has little to do with the number of cars on a road as the roads can be designed for almost any flow.

∙ 9y agoMany roads have "too many cars" without having traffic jams (All cars coming to a stop and causing traffic flow disruption) other roads are underutilized but do have these annoying flow interruptions. The causes of the traffic jams are linked more to driving habits and roadway design. The process is similar to "slug flow" in pipes when increasing flow interacts with bends and constrictions to interrupt the liquid flow as the flow transits between laminar and turbulent flow patterns.. Looking at the design, some roads have merges and poorly placed or times traffic signals which cause traffic to slow or halt. The stopped cars cannot be cleared before other cars arrive and are stopped and the blockage (jam) grows.
With regard to driving habits, some drivers move faster than others, some drive slower, some stop or slow for curves or interesting roadside events, some do not return to a proper speed as fast as others after slowdowns. All of these cause a reduction in the speed of some cas which then slow down even more and block following cars. Additive reaction time problems increase the blockage until traffic comes to a standstill.
A related problem is drivers choosing to be on specific roads at a time when traffic volume is higher (rush hours) rather than seeking alternate routes.
A solution would be to design roads to have proper timing on traffic lights, automatically controlled cars, designated routes for drivers chosen by a computer system. and staggered use times.
