Pedestrians are a part of vulnerable road users which safety requires a special attention. Official statistics in Estonia from the last decade returns the following numbers: around 30 % of all road traffic accidents in the country were accidents with pedestrians, 32 % of all traffic fatalities were finished with pedestrian death. Pedestrian crossing has the biggest risk level between all kinds of pedestrian facilities, because it includes a direct conflict point between vehicle and pedestrian traffics. The article presents a method to assess risk of pedestrian crossing users and to determine safety level of this road infrastructure element. This approach is based on observation and collection of infrastructural as well as traffic data, which includes: (1) information about each pedestrian crossing facility, its location and state, (2) data about accidents with pedestrians and their features, (3) data from road traffic measurements. The main advantages of the described method are universality and comprehensiveness. The case study was done in Kristiine district of the city Tallinn, which was chosen as the most typical average district of Estonian capital. Results of this study are also presented in the article.DOI: http://dx.doi.org/10.4995/CIT2016.2016.4124

Traffic conflict between turning vehicles and pedestrians is the leading cause of pedestrian fatalities at signalized intersections. In order to provide a solution for evaluating intersection safety for vulnerable road users, this paper first determines the most important factors in analyzing pedestrian-vehicle conflict and puts forward a pedestrian safety conflict index (SCI) model to establish a quantitative standard for safety evaluation of two- or multiphase intersections. A safety level system is then designed based on SCI to help categorize and describe the safety condition of intersections applicable to the model. Finally, the SCI model is applied to the evaluation of two intersections in the city of Changchun, the result of which complies with expectation, indicating the model’s potential in providing an improved approach for pedestrian-vehicle conflict evaluation study.

The Relationship

The main purpose of this study was to identify and analyze the prevailing types of accidents at roundabouts. The relationship was revealed between certain types of accidents, the place of their occurrence, and the configuration of the roundabout. The study analyzed 321 accidents at 19 ring intersections. Four predominant crash types were identified: rear-end collision, collision with vulnerable road users, side swipe collision, and entering circulate collision. The greatest number of accidents occurred at the weaving lane and at the entrances and exits of the roundabout. Dividing the ring intersections into separate sections to determine the location of the accident allows drawing conclusions on the nature of road traffic accidents and the impact of the roundabout design on safety.

Road traffic accidents (RTAs) are events that suddenly, inadvertently and unexpectedly occur under unforeseen circumstances that involve at least one moving vehicle and result in one or more road users being killed or injured. Unfortunately, Iraqi governorates suffer from higher rates of traffic accident casualties compared with the rates of casualties from terrorist attacks; this situation reveals a serious and growing problem. Road traffic accidents are not easy to eradicate. However, their prevalence can be reduced to the barest minimum via periodic assessments of traffic accident characteristics and the most important aspects for road authorities to consider when designing and evaluating the performance of a road to improve traffic and road users’ safety.Therefore, the primary objective of this paper is to evaluate traffic accidents in Baghdad using a retrospective analysis of accidents that occurred from 2006–2016 taking into consideration the following parameters: the cause of the accident, the genders of the victims, the number and type of vehicles involved in the accident, the time of the accident, the severity of the accident, the type of accident and the age group of the driver(s). The data were been obtained from the Central Statistical Organization in the Ministry of Planning. The results reveal that 12,019 RTAs occurred in the city of Baghdad; on average, 1,092 RTAs occurred each year. Twenty-two percent of the RTAs resulted in death, 67% resulted in injury and 6% resulted in both deaths and injuries. Only 4% of the RTAs resulted in property damage without victims. To this end, Baghdad has the highest prevalence of RTAs of all Iraqi governorates. These results provide scientific evidence to mobilize road authorities to effectively and urgently develop adequate traffic strategies and policies to reduce the epidemic of RTAs in Baghdad as well as other Iraqi governorates.

Speeding is one of the risk factors for road traffic crashes and deaths, especially for vulnerable road users. Research shows that increasing vehicle speed by 1 km/h can increase 4% -5% of fatal crashes. However, several other studies show that crashes are caused more by speed dispersion than by average speed vehicles in the traffic. This study aims to determine the effect of speed limit violations on the rate of a motorcycle crash on the national road in Bandung City. Although the proportion of motorcycles that violates the speed limit is quite high (40%), it turns out the result of this study indicates that the rate of motorcycle crash does not seem to be affected by the proportion of motorcycle in the traffic that violates the speed limit. Crashes involving motorcycles are more prevalent in the highest flow period than in the free flow conditions where the proportion of motorcycle that violates the speed limit is the highest. Mengendara dengan kecepatan tinggi merupakan salah satu faktor risiko penyebab kecelakaan lalu lintas dan kematian akibat kecelakaan lalu lintas, terutama pada kelompok pengguna jalan rentan. Penelitian menunjukkan bahwa peningkatan kecepatan kendaraan sebesar 1 km/jam dapat meningkatkan 4%-5% kecelakaan fatal. Namun beberapa penelitian lainnya menunjukkan bahwa kecelakaan lebih disebabkan oleh adanya variasi kecepatan di dalam arus dibanding kecepatan rata-rata kendaraan di dalam arus. Penelitian ini bertujuan untuk mengetahui pengaruh pelanggaran batas kecepatan terhadap tingkat kecelakaan sepeda motor di jalan nasional Kota Bandung. Walaupun proporsi sepeda motor yang melanggar batas kecepatan cukup tinggi (40%), ternyata hasil penelitian mengindikasikan bahwa tingkat kecelakaan sepeda motor tampaknya tidak dipengaruhi oleh proporsi sepeda motor di dalam arus yang melanggar batas kecepatan. Kecelakaan yang melibatkan sepeda motor justru lebih banyak terjadi pada kondisi arus tertinggi dalam satu hari dibanding pada kondisi arus lengang dimana proporsi sepeda motor yang melanggar batas kecepatan paling banyak.

Persistent problems related to traffic congestion, road safety and environmental challenges could be solved if people, vehicles, infrastructure and businesses were connected in a cooperative ecosystem. The creation of such an ecosystem has been key in the Horizon 2020 TIMON project, where it is the baseline for delivering information services related to traffic and multimodal transport to road users and administration drivers. The main objective of TIMON is to increase the safety, sustainability, flexibility and efficiency of road transport systems by taking advantage of cooperative communication and by processing open data related to mobility through a cooperative, open web-based platform and mobile app developed to deliver information and services to drivers, businesses and Vulnerable Road Users (VRU) in real time. TIMON has built up a large, strong community of more than 100 users (citizens) in the city of Ljubljana and has directly benefited their daily mobility and transport in the city, increasing their safety, cutting down pollutant emissions and curbing congestion. It has also impacted on at least 23 Intelligent Transport Systems (ITS) services companies, 31 road infrastructure managers & city administration and transport associations belonging to the Users’ Board of the project. This briefing seeks to present the benefits of the TIMON system for optimising traffic management and urban transport network operations in cities, directly supporting transport managers in their decision-making processes for transport operations. The briefing also explains how the TIMON solution has been deployed in the cities and the minimum requirements for it to work.

Abstract Background Among the largest Italian Regions, Piedmont (Northern Italy) had in 2017 a crude rate of road traffic accidents (RTA) deaths greater than the national average. RTA injuries remain a leading cause of injury deaths in Italy. Among them in both Piedmont and Italy many victims are vulnerable road users (VRU): pedestrians, cyclists and users of motorcycles or motorpeds. The study was aimed to describe their mechanisms of injury. Methods Observational study of the resident population in Piedmont from 2003 to 2015. Transportation Injuries (ICD-10: V01-V99) were considered, because of their greater comparability rate in bridge coding studies. A number of 5,185 RTA deaths was observed. Role, type of vehicle of the victim and collision were studied. Results Piedmont in 2017 had a RTA mortality rate (6.35 deaths per 100,000 inhabitants) greater than Italy (IRR = 1.13, 95% CI: 1.00 - 1.29; p < 0.02), 48.4% of the victims were VRU similarly to national data (49.8%). In the period the proportion of VRU on RTA deaths steadily increased from 25.6% in 2003 to 49.1% in 2015, in a significant way (z = 2.79; p = 0.005), because in a context of marked reduction of RTA mortality (-54.5%), the regional trend for VRU shows only a slight decrease (-12,6%). The VRU were: pedestrians (47.0%), motorized two-wheels users (37.4%) and cyclists (15.6%). Among pedestrians 63.9% deaths were caused by collisions with mainly automobiles (82.1%) and heavy vehicles (12.7%). In case of collision the prevalent causes of death were head injuries (41.5%) and multi-trauma (31.8%). Similar patterns were observed for cyclists, while in motorcyclists 56.5% of deaths were due to loss of control or fixed object. Conclusions VRU injuries remain a public health and social concern. Yet despite their extent, this problem is still not adequately considered in public health prevention programs. The observed mechanisms of injury evidence the importance to enhance the protection of VRU in road traffic circulation. Key messages In Italy, vulnerable road users are becoming a major group among road traffic injury deaths, because they not follow the general trend of large decrease of RTA injuries. Largest VRU group are pedestrians such as cyclists they are hit by cars or heavy vehicles with major trauma, in the motorized two-wheels loss of control and collision with fixed object are important.

The Impact

Background: Every year about 1.25 million people die as a result of road traffic injuries and half of those dying on the world’s roads are “vulnerable road users” like pedestrians, cyclists and motorcyclists. The objectives of the study were to assess the demographic characteristics of pedestrians and its effects on their crossing behavior and to identify the impact of technological and social distractions among pedestrians on road traffic accidents.Methods: A community based, observational study was conducted for the duration of 2 weeks from 15-Aug-2017 to 30-Aug-2017, all major Pedestrian traffic generating intersections of Shivamogga city were identified; among them three intersections were selected by simple random sampling. Data was collected for 5 days at each intersection for all the three intersections. Convenient sampling was used for sample size. Data on demographic and behavioral information for each pedestrian were recorded. Data was analyzed using SPSS 21 software.Results: Crossing behaviors of 468 pedestrians at Intersections were recorded. The majority (46.6%) of pedestrians were in the 25–44 year age category, more than half of the pedestrians observed were males (60.9%). Approximately 22.6% of pedestrians observed performed a distracting activity while crossing. Most of the pedestrians crossed the road by hesitating (32.1%) and by running (28.2%). Pedestrians with technological and social distractions were more prone for road traffic injuries (χ2=31.59, df=4, p=0.001).Conclusions: There is a need to implement pedestrian safety rules and to provide facilities for pedestrians in the infrastructure of roads in India and effective interventions to protect pedestrians.

AbstractBackgroundIn many developing countries there is paucity of evidence regarding the epidemiology of road traffic accidents (RTAs). The study determines the rates of injuries and fatalities associated with RTAs in Ethiopia based on the data of a recent national survey.MethodsThe study is based on the secondary data of the Ethiopian Demographic and Health Survey conducted in 2016. The survey collected information about occurrence injuries and accidents including RTAs in the past 12 months among 75,271 members of 16,650 households. Households were selected from nine regions and two city administrations of Ethiopia using stratified cluster sampling procedure.ResultsOf the 75,271 household members enumerated, 123 encountered RTAs in the reference period and rate of RTA-related injury was 163 (95% confidence interval (CI): 136-195) per 100,000 population. Of the 123 causalities, 28 were fatal, making the fatality rate 37 (95% CI: 25-54) per 100,000 population. The RTA-related injuries and fatalities per 100,000 motor vehicles were estimated as 21,681 (95% CI: 18,090-25,938) and 4,922 (95% CI: 3325-7183), respectively. Next to accidental falls, RTAs were the second most common form of accidents and injuries accounting for 22.8% of all such incidents. RTAs contributed to 43.8% of all fatalities secondary to accidents and injuries. Among RTA causalities, 21.9% were drivers, 35.0% were passenger vehicle occupants and 36.0% were vulnerable road users including: motorcyclists (21.0%), pedestrians (12.1%) and cyclists (2.9%). Approximately half (47.1%) of the causalities were between 15-29 years of age and 15.3% were either minors younger than 15 years or seniors older than 64 years of age. Nearly two-thirds (65.0%) of the victims were males.ConclusionRTA-related causalities are extremely high in Ethiopia. Male young adults and vulnerable road users are at increased risk of RTAs. There is a urgent need for bringing road safety to the country’s public health agenda.

Pedestrians and motorcyclists are vulnerable road users, being over represented in road traffic collisions (RTCs). One assumed benefit of road lighting is a reduction in RTCs after dark by countering the impairment to the visual detection of hazards that occur after dark. One way to optimise the use of road lighting is to light only those sections of road where light level, and hence visibility, is an important factor. The current study used change in ambient light level on RTCs to investigate those situations where improved vision is likely to have significant impact, and therefore the situations where road lighting is of better cost-benefit effectiveness. For both motorcyclist and pedestrian RTCs there was a significant increase in overall RTC risk in darkness compared to daylight, indicating that there may be an overall benefit of road lighting. While darkness was a particular detriment at junctions for motorcyclists and on high-speed roads for pedestrians, road lighting may not be effective mitigation in either case and therefore alternative ways of increasing conspicuity should be considered.
