Illegal pedestrian crossing at a traffic light: a study on tourist behaviour

Illegal pedestrian crossing situations at signalized intersections are observed worldwide. The main goal of this study was to observe attributes and determine the proportion and type of pedestrian violations and dangerous crossing situations at a traffic light located in a recreational tourist urban environment, i.e. the beach town of Viareggio on the coast of Tuscany, Italy. A large signalized intersection placed close to the beach was observed for some days in Summer 2015, for several hours, both in the morning and in the afternoon, to collect data. The main aim was to identify the illegal pedestrian crossing behaviour with red traffic light. Pedestrian crossing data were recorded with a video camera. Then, the video data were processed using a semi-automated software self-written in MATLAB to extract information on different pedestrian factors. Some factors, identified in the current literature as having an influence on the proportion of violations, such as age, sex and group size, were analysed. Furthermore, the impact of the amber length time on the proportion of dangerous performed crossings was studied. The obtained results highlight that pedestrians in a recreational tourist environment are generally more in compliance with traffic light than those in a weekday urban context. It is also important to pay particular attention to pedestrian yellow time (amber steady man) in order to avoid dangerous legal crossings. In fact it was often observed that pedestrians start to cross on the green walking man but end under the red light.
