context_page_description: Traffic congestion is a condition on transport that is characterised by slower speeds, longer trip times, and increased vehicular queueing. Traffic congestion on urban road networks has increased substantially since the 1950s. When traffic demand is great enough that the interaction between vehicles slows the speed of the traffic stream, this results in some congestion. While congestion is a possibility for any mode of transportation, this article will focus on automobile congestion on public roads.
  As demand approaches the capacity of a road, extreme traffic congestion sets in. When vehicles are fully stopped for periods of time, this is known as a traffic jam or a traffic snarl-up. Traffic congestion can lead to drivers becoming frustrated and engaging in road rage.
  Mathematically, traffic is modeled as a flow through a fixed point on the route, analogously to fluid dynamics.
context_section_description: In recent years, the Istanbul Metropolitan Municipality has made huge investments on intelligent transportation systems and public transportation. Despite that, traffic is a significant problem in İstanbul.
  İstanbul has chosen the second most congested and the most sudden-stopping traffic in the world. Travel times in Turkey’s largest city take on average 55 percent longer that they should, even in relatively less busy hours.
