I enjoying walking very much and the rewards are plenty. However, as a walker It is obvious that most people do not walk anywhere that is at least 15- 20 minutes walk away even if it is just to catch the bus to their destination which is a great pity yet understandable.
One of the aspects that completely spoils my walks is the pedestrian crossings, this is due to most of them being pedestrian unfriendly. Crossing the road is a very scary experience.( Try the North Circular in Palmers Green N13 a red route for example, this is a dreadful crossing that TFL is REFUSING to improve and is the reason the cycle lanes in the area have proven to be unpopular).
Moreover, due to our roads being pedestrian unfriendly they clearly discriminant against the elderly, parents/guardians doing the school runs and the disabled, therefore people will not change their travelling habits and pollution will continue to be a problem.
In essence, if our London Mayor is very serious about reducing pollution and improving peoples health by encouraging them to walk far more then our roads need serious addressing.
I have to say that it very perplexing that there is plenty of money for cycle lanes yet pedestrian crossing which includes the red routes are completely overlooked. Cycling is primarily for leisure unlike walking which offers more versatility in one's travel destinations particularly if one wants to do a a full shop.
As somebody who cares for the environment and is fed up with the amount of cars zooming and polluting our city I really had hope that our current London Mayor would had made this city a green, pedestrian friendly city with really safe pedestrian crossings, but as times passes it just seems that he will not be successful, he and his team are obviously finding it all very difficult to accomplish his initial vision.
