The speed trap campagin called "Blitzmarathon" is a building block in the general road safety work of the police. The study requested is therefore intended to demonstrate the effectiveness and sustainability of the speed camera marathon using the example of selected measuring points and to evaluate the transferability to the entire road network.
Exceeding the speed limit has a significant influence on the number of accidents and the severity of the consequences. Against this background, the "Blitzmarathon" has gained in importance, as it can have a positive effect on speeding behavior. The aim of the speed camera marathon should be to reduce the number and amount of speeding offences. This means the measure can only be evaluated at locations where there is a regular exceeding of the speed limit. The "Blitzmarathon" is not intended to result in all permissible speeds being significantly undercut, but rather to reduce high speeding in particular.
The comparative studies took place for both the speed trap campagin in October 2013 and the campagin in spring 2015 (16.4.2015). In October 2013, as part of a smaller study, only six locations were monitored where police surveillance also took place. In addition, the comparative data here were collected only ten days before and ten days after the speed camera marathon.
For the current accompanying study in spring 2015, the scope - both the number of comparison sites and the duration of the observation - was therefore significantly increased so that a final evaluation can be made. In this extended study, significantly more sites were covered and a differentiation was made between sections with and without police surveillance.
The required data basis was generated from traffic surveys (recording of individual vehicle data) and from data of the traffic management system of the city of Cologne. In this way, possible effects can also be demonstrated in the area and, in particular, the durability of the measure and the long-term effects can be better verified.
