- Abstract:
- At signalised pedestrian crossings, priority is given to vehicles and pedestrians are only allowed to cross after having registered their intent by activating the push-button on the traffic light pole. Thus, each of these two groups of users is allocated the right-of-way alternatively with the use of traffic signals, theoretically resulting in a conflict-free traffic guidance. But in practice, traffic conflicts arise due to jaywalking as well as red-light running. Thus, this master thesis examines this kind of misbehaviour encountered at signalised pedestrian crossings and aims at characterising red-light running of vehicles, quantifying its frequency as well as disclosing its influencing factors. On this basis, measures to improve traffic safety are deduced. In the course of a literature review the assessment criteria for the installation of signalised pedestrian crossings, their different signal programs and components as well as causes of red-light violations are investigated. Subsequently, traffic light offences, which were recorded by the Office of the Lower Austrian Government at nine signalised pedestrian crossings, are analysed. Especially their distribution concerning time-into-red and the risk experienced by crossing pedestrians are focused. Additionally, certain parameters (e.g. traffic volume, number of push-button activations) are evaluated concerning their impact on traffic light offences. Each day, 1,8 drivers ran the red light at each signalised pedestrian crossing. Thereby, pedestrians were hardly ever seriously endangered; one third of the red-light violations did not put any pedestrian at risk at all. Besides, it was shown that the amount of hourly push-button activations influences the probability of traffic light offences: The less frequently push-buttons were activated, the higher was the risk that the red light was run by a driver. Regarding remedial actions, a site-specific adaption of the signal programs or automated red-light enforcement is proposed.
