“…km/h, the fatality risk increases by about 46%. It should be noted that this increasing rate seems relatively small when compared with some existing studies [46] [47]. In this study, the model is actually on the basis of multiplicative effect of different factors.…”

Objective: Pedestrian safety is considered as one of the greatest concerns, especially for developing countries. In the year of 2015, about 48% pedestrian accidents with 56% fatalities occurred at mid-blocks in Beijing. Since the high frequency and fatality risk, this study focused on pedestrian accidents taking place at mid-blocks and aimed at identifying significant factors. Methods: Based on total 10,948 crash records, a binary logit model was established to explore the impact of various factors on the probability of pedestrian's death. Furthermore, first-degree interaction effects were introduced into the basic model. The Hosmer-Lemeshow goodness-of-fit test was used to assess the model performance. Odds ratio was calculated for categorical variables to compare significant accident conditions with the conference level. Variables within consideration in this study included weather, area type, road type, speed limit, pedestrian location, lighting condition, vehicle type, pedestrian gender and pedestrian age. Results: The calibration results of the model show that the increased fatality chances of an accident at mid-blocks are associated with normal weather, rural area, two-way divided road, crossing elsewhere in carriageway, darkness (especially for no street lighting), light vehicle, large vehicle and male pedestrian. With road speed limit increasing by 10 km/h, the probability of death accordingly increases by 46%. Older victims have higher chances of being killed in a crash. Moreover, three interaction effects are found significant: rural area and two-way divided, rural area and crossing elsewhere as well as speed limit and pedestrian age. Conclusions: This study has analyzed police accident data and identified factors significant to the death probability of pedestrians in accidents occurred at mid-blocks. Recommendations and improving measures were proposed correspondingly. Behaviors of different road users at mid-blocks should be taken into account in the future research.

“…These natural features make pedestrian behavior the least predictable for others. On the other hand, pedestrians have the least restrictions in the current traffic rules [26]. Accidents with pedestrians at the highest frequency are divided into two age groups: children under 15 years and persons over 65 years.…”

The article provides an analysis of the global trends in the field of city transport systems' safety. Currently, the efforts to increase the proportion of trips made by foot or by non-motorized transport are being made. That is why the problem of ensuring safety of the most vulnerable road users is relevant. The statistics of traffic accidents with victims, as well as the factors that cause such accidents, is analysed. Simulation has shown that rational management can reduce the likelihood of road traffic accidents.

Summary. The paper presents an analysis of road traffic accidents at non-signalized pedestrian crosswalks. A field study was conducted to determine the parameters for traffic and pedestrian flow, and construct the simulation models enabling experimentation at different loadings on the street and road network. Variants for improving the pedestrian safety at non-signalized crosswalks have been proposed. Simulation modeling of the proposed managerial decisions is expected to diminish the likelihood of road accidents. The efficiency of proposed decisions has been estimated. ОЦЕНКА ВОЗМОЖНОСТЕЙ ПОВЫШЕНИЯ БЕЗОПАСНОСТИ ПЕШЕХОДОВ НА НЕРЕГУЛИРУЕМЫХ ПЕРЕХОДАХ С ПОМОЩЬЮ ИМИТАЦИОННЫХ МОДЕЛЕЙАннотация. В статье проанализированы варианты возможных ситуаций возникновения ДТП на нерегулируемых пешеходных переходах. Проведены натурные исследования параметров движения транспорта и пешеходов на таких участках улично-дорожной сети. Определены параметры транспортных и пешеходных потоков, построены имитационные модели и проведены эксперименты на них при разных нагрузках на улично-дорожную сеть. Предложены варианты улучшения ситуации на нерегулируемых пешеходных переходах. Выполнена проверка на моделях предложенных управленческих решений, которые позволят снизить вероятность дорожно-транспортных происшествий. Выполнена оценка эффективности предложенных решений.
