  • IP0167 - Automated Vehicle Performance During Adverse Weather
    Coventry Tony

    Weather (atmospheric conditions) and road weather (pavement conditions) can adversely affect vehicle and driver behavior. With the advent of automated vehicles (AVs), the Federal Highway Administration Road Weather Management Program has begun research and testing to identify how vehicles and drivers will detect and react to adverse weather and road weather conditions. AVs have sensors and perception [...]

  • IP0238 - Floating Car Data for Monitoring of Road Friction - How to purchase friction data for a state agency
    Asp Anders

    Sweden has almost 100 000 km of state-owned roads. Winter maintenance is fully outsourced and divided into 108 maintenance contracts (maintenance areas). The contracts are performance-based with specific standard demands of road surface condition and road friction. The Swedish Transport Administration is facing two challenges – correlations of effects and measurement and follow-up. Correlations [...]

  • IP0007 - Road Surveying business – new tools with upcoming autonomous vehicles
    Jacopo Alaimo

    Road Surveying tools have significantly improved in the last 20 years with the introduction of advanced technologies like Lasers, Lidars, Accelerometers, and Stereo-Vision. These instruments allowed to speed-up the measuring campaigns and to move from qualitative to quantitative evaluation. Nevertheless, the cost of road mapping is still high, limiting the updates to larger organizations and making [...]

  • IP0168 - Optimization of vertical and horizontal traffic signals for communication of infrastructure with vehicles during heavy snowfall
    Zavasnik Zvonko

    Slovenia is situated in the part of the Alps where every winter we can expect several days of heavy snow. It is also bordering the Adriatic Sea which makes circumstances for safe traffic in the winter even worse: the combination of snow and strong wind namely bora creates snow drifts on road. This leads to covered of both horizontal and vertical signalization on the motorways with negative impact [...]

  • IP0266 - AHEAD - Una nueva tecnología para detectar el estado de las carreteras
    Gustavsson Torbjörn

    One of the great challenges that automated driving and ADAS is facing is the lack of knowledge about the friction and road conditions in front of a moving vehicle. Human drivers use input from the surroundings and their interpretation of the road conditions to adjust and adapt their way of driving. To enable the safe use of autonomous vehicles during snowy and icy conditions, the vehicles need to [...]

  • IP0303 - Cómo los datos sobre el estado de la carretera pueden extender el ODD y aumentar la disponibilidad de AD
    Rebecca Lewis Olsson

    How road condition data can extend the ODD and increase the availability of AD Adding prediction and detection of road weather contributes to the extension of the operational design domain, ultimately increasing the availability and performance of Autonomous Driving (AD) & Advanced Driver Assistance System (ADAS), which in the future will be the key to success for market leaders within the automotive [...]

  • IP0259 - Datos de vehículos flotantes para el control de la fricción en la carretera: recopile, perfeccione, almacene y visualice datos de vehículos flotantes
    Wallin Michael

    Advances in sensor technology, cloud computing and wireless communication makes localised, continuous and up-to-date data monitoring on the condition of road pavement available. The Swedish Transport Administration (STA) is conducting a program to develop, evaluate and implement a system for monitoring of road friction using connected floating car data. This paper presents the result of a project [...]

  • IP0236 - Gestión de la vialidad invernal realizada por la Dirección General de Carreteras en España
    Navareño Rojo Alvaro

    Most of the Spanish territory is affected during winter by snow or ice problems, so it is necessary to carry out winter maintenance works in more than 80% of the National Roads Network. Hence the importance of Winter Maintenance Management carried out by the General Directorate of Roads in order to ensure adequate traffic conditions. The National Roads Network (in Spanish RCE, “Red de Carreteras [...]

  • IP0022 - Información de fricción de los datos del coche flotante
    Sollén Sofia

    In Sweden today, control measurements of the road friction are done with special vehicles or equipment, often using methods generating spot-wise measurements. These methods that give low numbers of measurements only gives some information about the state of the road and are not enough to follow up of the friction requirements that are set by the Swedish Transport Administration, therefore the Swedish [...]

  • IP0145 - Información digital sobre las condiciones invernales de la carretera utilizando datos de vehículos flotantes - desde la investigación hasta la implementación
    Karim Hawzheen

    This paper presents a program which is conducted by Swedish Transport Administration to develop, evaluate and implement a system for monitoring of road friction using connected floating car data. The objective of the program is to improve traffic safety, increase productivity and reduce environmental impacts. Beside the evaluation of the technical aspects, the focus is also on the necessary prerequisite-creating [...]

  • IP0307 - La fusión de la monitorización del tiempo del tráfico y la información del vehículo en red en el frío entorno invernal. Investigación aplicada
    Guan Jian

    According to the climate characteristics of cold regions in winter, icy road , snow, fog and other environment are the main factors affecting traffic safety.The effective method of avoiding traffic accident is that the public to obtain the traffic conditions and meteorological environment in advance and choose the proper travel time and route.The road traffic meteorological monitoring equipment is [...]

  • IP0217 - Poner a disposición del público las aplicaciones web de mantenimiento invernal: sí o no
    Janeba Julius

    Public roads in the Czech Republic reach the length of 56,000 km. They are divided into 4 categories. The most important motorways and Class I roads (7,244 km) belong to the state organization Road and Motorway Directorate. The remaining roads Class II and III are owned by 13 the Regions, the Capital City Prague has a special status. Winter maintenance is provided either directly by the organization [...]
