Week 4

This week so far I learn more about the traffic tech which is being implemented in Cambirdge, UK.

There is a system that according to this post https://www.smartertransport.uk/smart-traffic-management/, has taken relevanced and important attention from the people who lives in Cambridge.

Smart Traffic Management is a system where centrally-controlled traffic signals and sensors regulate the flow of traffic through the city in response to demand.

Cambridge is a typical small UK city. Currently it has some elements of a Smart Traffic Management system, but most traffic lights are not connected into it, and some features are not being used.

Upgrading and integrating all the signals on the main roads in the city will:

  • Reduce everyday congestion markedly, by smoothing traffic flows and prioritising traffic in response to demand in real time.
  • Reduce pollution throughout the city: stop-start driving is inefficient and polluting.
  • Give priority to buses approaching junctions, phasing lights to give traffic flowing with buses a ‘green wave’ through the city.
  • Enable a much more effective response to traffic incidents, especially on the A14 and M11. The system can be pre-programmed to handle a sudden increase in traffic on any of the ten radials.
  • Enable Inbound Flow Control.
