Journal Article
Quddus, M. A., Bell, M. G., Schmöcker, J.-D., & Fonzone, A. (2007). The impact of the congestion charge on the retail business in London: An econometric analysis. Transport Policy, 14(5), 433-444. https://doi.org/10.1016/j.tranpol.2007.04.008

On 17 February 2003, London introduced a pioneering congestion-charging scheme. The impact on traffic was sudden and dramatic. For example, car movements within the congestion-charging zone (21km2) were reduced by about 30%. However, the impact on ot...

Car driver speed choice in Scotland (2007)
Journal Article
Stradling, S. G. (2007). Car driver speed choice in Scotland. Ergonomics, 50(8), 1196-1208. https://doi.org/10.1080/00140130701318681

Drivers who commit driving violations, such as speeding, crash more. Driving violations reduce safety margins amplifying the impact of driver errors. Speed is placed in the context of car use and its attractions. It is argued that speed choice result... Read More about Car driver speed choice in Scotland.
