City corridors - characteristics and air quality
City corridors are busy mixed-use routes that historically served as tram routes but now suffer from over-sized road infrastructure, traffic congestion, and air pollution, with four routes designated as air quality management areas exceeding EU standards.
The city corridors into and out of the city are typically characterised by a mix of uses fronting onto a busy road. Historically the city corridors were the key tram routes serving an expanding city. However increasing car ownership, and the growth in commuting, has resulted in road infrastructure that is over-sized, over-complicated and a barrier to non-motorised accessibility. A consequence has been traffic congestion and air pollution problems, which has degraded the environment of the city corridors. Four such routes have the designation of air quality management areas in the city where pollution levels exceeds EU standards.
