PEDESTRIANS’ SAFETY IN POLAND AND USE OF REFLECTIVE MATERIALS

The subject of pedestrian safety is particularly important in Poland, where the risk of mortality is very high compared to other European Union (EU) countries. In Poland, 60% of all killed pedestrians lost their lives at night, mostly away from urban areas. The current article focuses onpedestrians’compliance with the law requirements of the mandatory use of reflective elements at night in non-urban areas since its introduction in Poland in 2014 based on adata analysis and survey on pedestrians’ attitudes and behaviours. An analysis of pedestrian accidents, fatalities, and serious injuries at night five years before and five years after 2014 showed an improvement inpedestrian safety more in non-urban areas (where the law on reflective elements is obligatory) than in urban areas. This study is the first published work to present comprehensive results from an in-depth national survey about people’sattitudes and behaviours regarding theuse of reflective elements. The data were obtained from 600 observed and 400 questioned pedestrians in 2018. Observationsfrom 2018 showed that only 21% of pedestrians respected the obligation towear reflective elements at night outside urban, even though 46% of respondents declared in questionnaires that they wore such elements. Pedestrians who usedreflective devicesin non-urban areas at night were mainly young people aged 40 years old or younger. They used reflective clothing (shoes, trousers, backpacks); 79% of observed pedestrians did not wear reflective elements at night according to questionnaires from 2018. More pedestrians (60%) who didn’t use any reflective wore black clothing, whichmade them not visible to drivers and put them atrisk of being killed. A comparison of thedata showed a positive change in pedestrians’ attitudes due to this obligation.In 2015 only 35% of respondents knew that the use of reflective elements was obligatory in some situations; in 2018, almost half of them (46%) did. The analysis carried out in the present study indicated that the preventive action of introducing the mandatory use of reflective elements at night by pedestrians outside urban areas has slowly improved the safety of pedestrians anddecreased the numbers of accidents, seriousinjuries, and fatalities. Changes introduced intoPolish traffic rules have improvedpedestrians’ safety on roads since 2014; however, there is still an immense need tocarry on social actions and campaigns promoting the use of reflective elements to educate road users to change pedestrians’ behaviours.

Statistical analysis and accident prediction models leading to pedestrian injuries and deaths on rural roads in Iran

The purpose of this study was to develop models to predict the severity of pedestrian accidents on rural roads of Guilan, Iran. Therefore, the probability of occurrence of any type of accidents was measured using the accident data from March 2014 to March 2019. Eleven independent variables affecting the severity of pedestrian accidents as well as statistical analysis such as the frequency analysis, Friedman test and factor analysis, and modeling including multiple logistic regression and artificial neural networks using multi-layer perceptron (MLP) and radius basis function (RBF) have been used. Results of modeling and analysis of pedestrian accidents in different methods showed each of the methods depending on their function investigated the severity of accidents with different point of view and had different results. As a result, putting the output results together, the best measures can be suggested to increase the safety of pedestrians on the rural roads of Guilan.

무단횡단 금지를 위한 차선분리대 신뢰성 평가

The Government has recently selected and is implementing the safety measures for ensuring the safety of pedestrians in living zone in order to reduce the number of traffic casualties by half. This study has carried out researches on the analysis of pedestrian accidents, the criteria for performance evaluation of jaywalking ban facilities, and the performance evaluation of jaywalking ban facilities lane divider. As a result, we have analyzed the failure mechanisms of material damages, support bar bending, the bar fracture, anchor-pullout, lower fixed shear fracture, reflection performance degradation of the reflective sheet, etc. due to vehicle crashes, which are the factors in the failure of the lane divider for jaywalking ban, a road safety facility. We have also developed a reliability evaluation method which is able to reproduce those failures. As a result of evaluating the reliability of the jaywalking ban facilities lane divider product, we have been able to assess the criteria for reliability evaluation which is an important measure to durability, and to provide a guide for the reliability of reasonable level of the product quality.

Fusion of cooperative localization data with dynamic object information using data communication for preventative vehicle safety applications

Abstract. Cooperative sensors allow for reliable detection, classification and localization of objects in the vehicle's surroundings – even without a line-of-sight contact to the object. The sensor principle is based on a communication signal between the vehicle and a transponder attached to the object of interest – a pedestrian, for example. Thereby, localization information is gathered by measuring the round-trip time-of-flight (RTOF) and evaluating the angle-of-arrival (AOA) of the incident signal. After that, tracking algorithms are used to recover the kinematic state of the object providing a basis for situation assessment. This paper investigates possibilities and benefits of extending this principle by the communication of information from inertial sensors which are locally attached to the transponder. Furthermore, this paper presents a robust approach for fusing the localization data with dynamic object information using the Dempster-Shafer theory. The approach is evaluated by performing real-world experiments for the analysis of pedestrian accidents.

Analysis of Pedestrian Accidents in Irbid City, Jordan

The numbers of people who are walking and bicycling continues to increase all over the world and pedestrian accidents are becoming a serious problem in the developed and developing countries. However, the problem is more severe in the developing countries, such as Jordan where pedestrians represented 32.5% of all traffic accident fatalities and 23.8% of all traffic accident injuries during the year 2010. This study aims at analyzing pedestrian accidents in Irbid city, as an example for urban areas in Jordan, based on a total of 1090 pedestrian accidents that have occurred in the City during the three years period (1999 - 2001). The analysis was based on pedestrian characteristics, driver characteristics, accident time, accident location, weather, road surface condition, illumination condition, vehicle characteristics, speed limit, accident severity, pedestrian faults, and driver faults. Geographic Information System (GIS) tool was used to locate all pedestrian accidents over the study area. The results of the study showed that the majority of pedestrian accidents have occurred at non-intersection locations, during clear and sunny weather, on dry surface, during daylight, and at low speed limits. Also, more pedestrian accidents have occurred during the afternoons, on Thursdays, and during July. The majority of involved drivers in pedestrian accidents were males, with private license type, driving private vehicles and committed the fault of “not giving priority to pedestrians”. The majority of pedestrian victims were males, children less than 15 years old, and hit by vehicles while crossing the road.

Pedestrian accident analysis with a silicone dummy block

When a car is parked in an inclined plane in a parking lot, the car can roll down the slope and cause a pedestrian accident, even when the angle of inclination is small. A rolling car on a gentle slope seems to be easily halted by human power to prevent damage to the car or a possible accident. However, even if the car rolls down very slowly, it can cause severe injuries to a pedestrian, especially when the pedestrian cannot avoid the rolling car. In an accident case that happened in our province, a pedestrian was injured by a rolling car, which had been parked on a slope the night before. The accident occurred in the parking lot of an apartment complex. The parking lot seemed almost flat with the naked eye. We conducted a rolling test with the accident vehicle at the site. The car was made to roll down the slope by purely gravitational pull and was made to collide with the silicone block leaning against the retaining wall. Silicone has characteristics similar to those of a human body, especially with respect to stiffness. In the experiment, we measured the shock power quantitatively. The results showed that a rolling car could severely damage the chest of a pedestrian, even if it moved very slowly.

Analysis of Pedestrian Gait and Perception-Reaction at Signal-Controlled Crosswalk Intersections

Pedestrian accident analysis and reconstruction remain the most difficult areas for the accident analyst. Although data relating to average pedestrian walking speeds, perception-reaction, and pedestrian accident reconstruction can be found in the literature, proper pedestrian study data pertaining to real-life situations are lacking. Pedestrians were observed at signal-controlled crosswalk intersections, and their perception-reaction to the crosswalk signal, acceleration rate to reach constant walking velocity, and average walking speed once steady state velocity is achieved were determined. Experimental test data collected regarding pedestrian gait analysis, initiation, and steady state walking speeds are presented. “Real world” pedestrian observations were gathered at a variety of intersections, ranging from busy downtown intersections to suburban intersections throughout the greater Los Angeles area. Kinematic data on pedestrian movements were obtained using high-speed digital video. A high-speed video motion analysis system was used to reduce the data and to obtain the mean acceleration and time to steady state walking velocity. Perception-reaction data collected on 288 subjects show a significant percentage of the pedestrians initiating movement within 1 s of Walk light illumination. Some differences were observed when the state of anticipation was being considered, and these results are presented. The mean acceleration (0.14 ± 0.09 g) and steady state velocity (1.36 ± 0.24 m/s) values did not demonstrate a significant difference between males and females. The width of the street or initial state of anticipation did not have an effect on either mean acceleration values or steady state velocities.

Using Medical Records in Non-Motor-Vehicle Pedestrian Accident Identification and Countermeasure Development

A study was conducted to determine the feasibility of using emergency room and emergency medical service records in quantifying rural non-motor-vehicle pedestrian accidents and in developing countermeasures to reduce injuries resulting from such accidents. A literature review indicated that although non-motor-vehicle pedestrian accidents are a significant injury problem in the United States, there does not appear to be an effective process for collecting data about those accidents that corresponds to the data collection methods used at present for motor-vehicle accidents. A multistep process for obtaining detailed pedestrian accident data using a combination of medical records and telephone surveys is described. Data collection was time consuming and labor intensive. Therefore, it was concluded that it is not practical for traffic engineers to use medical records on a routine basis for pedestrian accident analysis. The method outlined yields a data base rich in details about pedestrian fall accidents, making it valuable in research. Whereas the results of the telephone survey did not produce a large enough sample size to extrapolate to pedestrian accidents in general, they did point out the importance of surface condition to pedestrian safety. Two general types of surface-condition problems were identified: slippery surfaces caused by accumulation of snow and ice and surface holes or openings.

The Harstad injury prevention study: hospital-based injury recording used for outcome evaluation of community-based prevention of bicyclist and pedestrian injury.

To test the feasibility of a hospital-based injury recording for accident analysis and outcome evaluation of bicyclist and pedestrian injury prevention. Prospective injury recording lasting 7 1/2 years, using a quasi-experimental design. The population of Harstad (22,000). Injury data were evaluated in an injury prevention group and used in planning a community-based intervention. Promotion of bicyclist helmet use and pedestrian safe behaviour was implemented by activating public and voluntary organizations and media. A traffic safety pamphlet containing local traffic injury data was distributed. Changes were made in the physical traffic environment. Injury rates for bicyclists and pedestrians. In 275 bicyclists upper extremity and head injuries were predominant 70% were below 16 years. In 137 pedestrians lower extremity injury was most frequent and children below 10 years had the highest injury rates. Significant injury rate reductions were observed after intervention for child bicyclists and pedestrians. A hospital-based injury recording is feasible for bicyclists and pedestrian accident analysis, planning injury prevention, and outcome evaluation of the programme. This study indicates that a significant injury rate reduction in children may have been the result of the intervention.
