Alternative mathematical theories exist, such as Boris Kerner's three-phase traffic theory (see also spatiotemporal reconstruction of traffic congestion). In a capitalist economy, goods can be allocated either by pricing (ability to pay) or by queueing (first-come first-served); congestion is an example of the latter. levels have increased in every area over the history of the study. They were among those stuck in a three-day traffic jam at a toll exit in Brebes, Central Java called 'Brexit'.

It has been argued that traffic congestion, by reducing road speeds in cities, could reduce the frequency and severity of road accidents.[32]. He warned that roads were in serious danger of becoming so congested that the economy would suffer.

A 2011 study in The American Economic Review indicates that there may be a "fundamental law of road congestion." Key to the study is the realization that the mathematics of such jams, which the researchers call "jamitons," are strikingly similar to the equations that describe detonation waves produced by explosions, says Aslan Kasimov, lecturer in MIT's Department of Mathematics. Their working traffic models typically use a combination of macro-, micro- and mesoscopic features, and may add matrix entropy effects, by "platooning" groups of vehicles and by randomising the flow patterns within individual segments of the network. Australians rely mainly on radio and television to obtain current traffic information. Roughly half of congestion falls under the recurring category, which happens due to a lack of enough road capacity to accomodate a high number of … Promotion of more flexible work place practices.

"[87][88] The congestion is regarded as the worst in history by duration, and is one of the longest in length after the 175 kilometres (109 mi) long Lyon-Paris traffic jam in France on February 16, 1980. Instead of the traditional solution of making the "pipe" large enough to accommodate the total demand for peak-hour vehicle travel (a supply-side solution), either by widening roadways or increasing "flow pressure" via automated highway systems, Downs advocates greater use of road pricing to reduce congestion (a demand-side solution, effectively rationing demand), in turn plowing the revenues generated therefrom into public transportation projects.
