The increase in the proportion of the worlds population
What are causes of increased traffic in CBD?
Commuters : 25% of workers are commuters creating severe congestion especially during rush hour. Few bridging points : Cars are funnelled into bottlenecks at various bridges. Narrow streets : Car parking on streets makes it difficult for cars to flow up and down streets. It also restricts the view of the driver making it dangerous for pedestrians to cross. Increasing car numbers
What are improvements in public transport?
More bicycle lanes for cyclist to travel safely. M74 was extended to offer another quick route to the city centre. More bus lanes and taxi lanes so it is quicker for people to travel.

Co2 emissions reduce in CBD but increase in suburbs. Area becomes more run down. Habitats are destroyed. People move out of area
What were changes in the inner city
Tenements were built close together because people had to go to work so it had to be easy and accessible. Many flats were divided up due to lots of people flooding into Glasgow and more families needed homes. Glasgow city council had to redevelop inner city due to over crowdedness and urban decay
Describe ways to prevent urban sprawl
Introduce greenbelts - protected land makes it very difficult to gain planning permission. Brownfield sites - encourages developers to reuse land within city boundaries by offering loans or incentives. Prevent retail parks - planning permission for out of town shopping centres now requires permission of Scotlands first minister
