“…Pedestrian crossings may be located next to a junction or on road sections between junctions. Where at-grade crossings are involved, pedestrians and motorists interact, which may lead to dangerous situations and road traffic conflicts [1,2]. These mutual interactions between infrastructure users determine how pedestrian crossings operate.…”

Cities (especially in Central and Eastern Europe) focus on improving the road network, which aims to improve the efficiency of motor traffic and minimize congestion. Most of existing tools for analysing the effectiveness of urban transport networks do not assume to analyse the impact of walking and cycling on efficiency of transport systems. It is therefore necessary to develop solutions that on the one hand will reduce congestion, and on the other hand, improve the safety and quality of travel of vulnerable road users. One of the tasks to be developed in order to improve pedestrian conditions is to determine the relationship between pedestrian and vehicle traffic. An attempt has been made to establish the relationship between pedestrians and vehicle traffic in order to describe traffic conditions and pedestrian safety at pedestrian crossings. The analyses were based on simulations carried out using the PTV Vissim/Viswalk software and with the use of surrogate safety measures.

Investigation of traffic conflicts at signalised intersections in Warsaw

et al. 2019

Although traffic safety situation in general is improving, the numbers of pedestrians and cyclists hit when crossing a road have not significantly decreased recently. Based on police accident records for years 2010-2014, some 735 pedestrians and 505 cyclists were hit by motor vehicles in Warsaw. Investigation reported in this paper is a part of the European project InDeV. One aim of the project is to find correlation between accidents and traffic conflicts and thus provide a solid base for using surrogate safety measures as safety diagnostic tools. Three typical signalised intersections in Warsaw were selected for video recording. Relevant encounters between motor vehicles and vulnerable road users (pedestrians and cyclists) were identified and analysed using programs RUBA and T-Analyst. The paper describes the semiautomatic video data processing and problems regarding some technical and methodological aspects of conflict detection. Based on video analysis of 24 hours of recording for each intersection, preliminary characteristics of encounters between pedestrians/cyclists and motorised vehicles have been developed. Statistical distributions of encounter parameters such as time-to-collision (TTC) and post-encroachment time (PET) are presented. These will be used in the development of appropriate safety indicators.

“…Numerous improvements in modern vehicles such as the new designs on outer vehicle shape, novel body front-end materials, incorporating the active and passive protection systems into the modern vehicles have been the main research subject in the automotive industry. As a result of this kind of advances, for instance, during the years 2009-2013 in EU countries, the fatality and serious injury rate of the pedestrians reduced by more than 17% [4].…”

Pedestrians are the high-risk group in vehicle accidents, especially in urban areas. In the world, every year numerous pedestrians die by vehicle impacts. Therefore, the pedestrian protection is one of the most crucial subjects in automotive manufacturers, and many governments are releasing more drastic regulations. However, in the traffic there is a considerable amount of the cars running which have been produced before pedestrian safety regulations. In this study, the pedestrian head impact on an energy absorber material covered steel bonnet was investigated by finite element method. The pedestrian head impact is the first reason for the fatality in the vehiclepedestrian accidents. The pedestrian head-form is used for simulations according to EEVC/WG17 regulations. The foam cover and hood thicknesses are the parameters in the impact simulations. Results of the impact analyses are compared with each other by head injury criterion calculations. The head injury criterion values are accepted for measuring pedestrian's head injury level. In the study, various thickness hyperelastic foams were used in top layer as a cover. Moreover, also developed layered structure designs by steel, and hyperelastic material layers were discussed on light-weighting.
