According to the GCSE syllabus, you have to be able to describe a solution to traffic problems in urban areas. The Barclays Cycle Hire scheme in London is a good case study to use. The video explains how it works:
This animation shows the movement of the “Boris Bikes” on a busy day (there was a worker strike on the London Underground so many people used a bike for the first time) How succesful does the scheme appear to be?
The next animation focuses on journey times. The darker the colour the longer the average ride. The animation shows that workers in the business and banking part of the CBD (the City) tend to take shorter journeys and that people living in the west of the city tend to ride a greater distance. The entertainment and leisure part of the city (the West End) also features longer journeys. Can you think of factors that might explain the patterns?
The animated maps were sourced from the amazing Mapping London blog.
