Abstract

Within the category of vulnerable road users pedestrian are recognised as those with the highest probability in road accidents to be affected by serious or fatal casualties. However, due to the randomness of their behaviour and sometimes the limited attention of traffic light operation settings devote to this road user category, in particular in isolated signalised junctions, there is a huge potential in the capability of new and intelligent systems to play a fundamental role in the improvements of pedestrian safety. In this paper an in-depth analysis of a 4 arms isolated signalised urbanjunction located in a small town in Sicily (Italy) has been carried out.In-depth analysis, differentiating by time of the day, gender, age and junction arms has been carried out and impact in terms of variation in safety levels have been assessed. From the lesson learnt potential impact of the implementation of new and intelligent systems such as puffinand pelican crossing modifying the signal settings and/or the junction layout have been assessed. The paper then concludes with a comparison of the safety levels of the current settings against those related to the week when variable traffic light settings have been implemented.
