  • IP0386 - A Control Speed of 80 km/h for Rural Roads in Germany
    Sven-Martin NIELSEN

    In 2021, around 60% of people who died in road traffic accidents in Germany died on rural roads (over 1,400). Outside of pandemic periods, these figures were even higher, as also shown by the unpleasant developments in 2022, but the proportion of all people killed on roads has been stable for years. Serious injuries on rural roads accounted for 40% (21,778 people). The main cause of accidents is excessive [...]

    Carlos AZPARREN CALVO , José PAPÍ , Friederike KÜHL

    In Europe today, 23,000 fatalities and 900,000+ road accidents involving personal injuries happen every year, with high costs on the infrastructure and irreversible losses of human lives and - not less important - thousands of persons permanently injured or severely handicapped. An EU programme sought to reduce road fatalities by 50% in 2030, and supported CEN introducing the EN1317 standard for [...]

  • IP0331 - Analysis of the effectiveness of various traffic calming measures in single and double carriageway roads affected by works
    Heriberto PEREZ-ACEBO

    Despite the reduction in the number of crashes and killed people in the last decades, road safety continues to be an important problem worldwide. Although several measures are being conducted to reduce the accidental rate both in rural and in urban road networks; there is still a recurrent dangerous place: roads affected by works. This affection can be due to rehabilitation or maintenance activities [...]

  • IP0252 - Applying Cycling Infrastructure to Large and Complex Intersections, a Cross-national Analysis
    Scott BRODY

    This paper describes unique challenges impacting the development of bicycle infrastructure in the vicinity of very large roads. In certain situations, it is impossible to construct junctions in compliance with standard cycletrack offsets. In Eastern Europe, road authorities have modified the protected intersection in a way that addresses such challenges. These crossings often have offsets well above [...]

  • IP0723 - Are bike lanes dangerous? Investigating cycling infrastructure effect on safety.
    Michal SINDELAR

    The research explores the relationship between the implementation of cycling infrastructure and road safety. Due to the availability of data on motor vehicle and cycling traffic intensity in street network of Prague, it was possible to construct an indicator of relative safety considering the exposure to crash risk. The relationship between different types of cycling infrastructure and cycling safety [...]

    Czech Road Traffic Safety Strategy 2021–2030 (hereinafter referred to as the ‘Strategy’) builds upon Czech Road Traffic Safety Strategy 2011–2020 and European Commission White Paper 2002–2010 called ‘European Transport Policy for 2010: Time to Decide’. The priorities are in line with the targets set by the Member States of the European Union and the United Nations, which have set the [...]

  • IP0093 - Development of the integrated road infrastructure safety investment program in Romania

    The annual number of deaths in road accidents on Romania's public roads has been about 1,850 in recent years. Their mortality rate for 2020 is around 85 deaths per million inhabitants and is one of the highest rates in the EU and almost two times higher than the EU average, even though it has been declining over the last 15 years. In order to achieve a safer road infrastructure, Romania is taking [...]

  • IP0089 - Effects of Dynamic Factors and Regional Climate Variability on Motorway Safety
    Matthew HALL

    Increased population, societal shifts and changed utilisation of roads have increased competition for road space. Dynamic spatiotemporal factors resulting from higher traffic density and flows on urban motorways are increasingly influencing road users, vehicles, and road safety outcomes. Trends in dynamic traffic factors in relation to safety are examined. Vehicle event data, corresponding reported [...]

  • IP0213 - Evaluating Emergency Escape Ramps properties in Indonesian Expressways
    Alfa Adib ASH SHIDDIQI

    Based on Indonesian National Police data, the number of deaths due to road accidents in 2019 has reached 25,671 people, or equivalent to 3 (three) deaths per hour. The highways (toll roads), currently operate more than 2000 km, with over 4,572,142 average daily traffic contributing heavily to that number. Since road accidents are prominent issues in highway operations, the geometric design should [...]

  • IP0451 - Exploring Heinrich'law by examing spatial relationship between minor accidents and severe accidents

    This research explores the spatial association between police-reported crashes and near-miss crashes experienced by road users using the network cross K-function method and GIS. The near-miss crashes were collected from a field survey conducted in Seoul, South Korea, and police-reported crashes in the study area were also collected for comparison. The results show that minor and severe police-reported [...]

  • IP0499 - Investigating the Effects of Roadway Attributes on Traffic Safety in Urban Mixed Traffic Environment
    Kun-Feng WU

    With the increasing use of powered-two-wheelers (PTWs) in many urban areas, especially in Asia, the number of PTW-related crashes, fatalities, and injuries are increasing. PTW fatalities even account for more than half of all road deaths in many Asia countries. Nevertheless, there has been limited research on which roadway attributes are influential to traffic safety in urban mixed traffic environment [...]

  • IP0015 - Preventing Deer and Moose Accidents through Road Management Measures – Experiences and Solutions from Finland
    Jaakko KLANG

    More than 13 953 traffic accidents involving deer and moose are estimated to occur each year in Finland. These accidents cause at least €92 million in costs and lead to 122 personal injuries (3 fatalities) annually. Deer-related accidents are increasing as both deer populations and vehicular travel increase. In this presentation, I will describe the methods and measures that have been used and [...]

    Stephanie DAVY

    There is growing evidence that Raised Safety Platforms (RSPs) are an effective intervention to target key crash problems at urban signalised intersections. A before-and-after study including control sites has been conducted to compare traffic performance prior to and after the installation of RSPs along two arterial routes in Victoria, Australia, with encouraging results. The evaluation that was undertaken [...]

  • IP0698 - Road Management System in Adverse Weather Conditions: Fog and Wind
    Laura REY RAMOS

    The A-8 Cantabrian motorway (A-8) in the area of Alto del Fiouco, between km 545+500 and 549+500, presents particular weather conditions with episodes of dense fog combined with strong winds that complicate traffic, sometimes making it necessary to close it and detour vehicles to the N-634 road, as it is not possible to guarantee the minimum safety conditions for its use. For this reason, the Directorate [...]

  • IP0097 - Road safety: method for a reconstruction of the accidental scenario

    In France, after the awareness of the 1970s and the political agenda set in 2002, remarkable and unprecedented results have been achieved in road safety. However, the ambition remains not to consider road mortality as a price to pay for modernity, and the new objectives set in relation to international standards such as those of the WHO or the UN will not be achieved. Worse, since 2013, the indicators [...]

  • IP0163 - Safer car drivers and safer roads through a data and risk-based approach to road safety
    Menno MIMPEN

    Road authorities are increasingly looking for ways to improve road safety by a data and risk driven improvement of the road infrastructure. This is also the result of the 2050 Vision Zero strategy. Data on car driver behaviour provides important insights related to the risk of accidents. This data shows how individual drivers behave and also how they interact with the road infrastructure because [...]

  • IP0057 - School Zone Road Safety Assessment Using the iRAP Star Rating for Schools (SR4S) Methodology in Khorasan Razavi Province

    Students who walk to school often have to deal with traffic, weather conditions and other distractions along the way. Every hour, nearly 150 children between ages 0 and 19 are treated in emergency departments for injuries sustained in motor vehicle crashes. More children ages 5 to 19 die from crash-related injuries than from any other type of injury. In this project which was supported by the Global [...]

  • IP0207 - Some Common Infrastructure-Related Safety Deficiencies on Nigerian Roads

    With the end of the First Decade of Action for Road Safety (2011-2020) and the commencement of the Second Decade of Action for Road Safety (2021-2030), all efforts are directed towards the attainment of safer roads. Safer roads lead to reductions in road traffic crashes (RTCs), and serious injuries, fatalities, and loss to the economy associated with RTCs. Safe infrastructure is important contributory [...]

  • IP0319 - The Rights for Safer Roads for Pedestrians in Indonesia Case Study: The Walkability Index in Three Metropolitan (Bandung, Medan, Makassar) Along the Bus Rapid Transit Lanes

    Walking is the most common act of movement. Walking is also a part of our daily life. From point A to point B most likely will involve some walking. Even to get to any transport mode, we start and finish the journey by walking. Pedestrians supposedly walk on their dedicated lanes be it sidewalks, crossings, bridges, or tunnels. And it has to be well understood that road users are not only those on [...]

  • IP0447 - The road safety situation in Tunisia. How to get out of the bottleneck?
    Mohamed Souleimen OUANNES

    As in most parts of the world, the scourge of traffic accidents is a major public health issue and a social and economic problem. In addition, road safety generates colossal expenses for the community as well as for households and companies and constitutes, in fact, a flagrant waste of resources. This phenomenon, which is beginning to be controlled in many industrialized countries, remains explosive [...]

  • IP0640 - V2X- and AI-based improvement of short-term roadworks sites personnel safety
    Torben SCHENKEL

    Measures for the maintenance and operation of roads (e.g. reparation of potholes, road marking) are generally implemented within the framework of short-term roadworks sites. Safety Trailers, traffic cones or warning beacons are installed in stationary short-term roadworks sites to separate the traffic area from the work area. This means that the personnel are not protected by solid protective devices [...]

  • IP0408 - Visibility and Road Safety at T-Junctions
    John-Paul DOHERTY

    Highways Engineers and Planners often rely on priority junctions, often known as T-junctions, as the simplest and cheapest way of connecting new developments to the existing road network. Whilst priority junctions may be the simplest and most common junction on our roads, they are also one of the most dangerous junction forms. In Great Britain there are nearly 30,000 collisions a year at priority [...]
