Portorož, Slovenia MARVin–Model for Assessing Risks of Road Infrastructure DI Peter SalehDI Peter Saleh arsenal researcharsenal research Project managerProject manager

Portorož, Slovenia Idea of MARVin Road conditions (RoadSTAR*) Accident data Linked by the location of accident *Road Surface Tester of arsenal research

Portorož, Slovenia Idea of MARVin Combine detailed information on: oRoad Geometry (horizontal curvature, gradient and crossfall), oRoad Surface Condition (roughness, rut depth, texture depth and skid resistance) oand Road Accidents.

Portorož, Slovenia RoadSTAR – Road Condition Monitoring oSkid resistance oTexture (cracks) oTransverse evenness (ruts) oRoughness o measured values/km at 60 km/h Pavement Management - Road Safety

Portorož, Slovenia RoadSTAR – Registration of route/trace parameters Inertial navigation gyre incl. dGPS-System oCurve radius oTransverse slope oLongitudinal slope oActual longitudinal profile oRegistration of lane (Possibility of creating route graphs)

Portorož, Slovenia MARVin – Road Safety Analysis oVisualisation and elaboration of road condition data with arSis (arsenal research road information system) oCorrelation with road safety data oPrognosis of scenes of accident oAccident prevention oReconstruction expertise, reconstruction plans

Portorož, Slovenia MARVin – Motorcycle Safety Analysis Curve radii vs. Accident Types (sample: 1358 accidents)

Portorož, Slovenia MARVin – Current Results Average crossfall (q-avg) + average gradient (s-avg) – 100m before the position of accident (run-off accidents; sample: 5918 accidents) … road condition: DRY… road condition: WET

Portorož, Slovenia MARVin – Current Results 3D-Histogram: Average crossfall (q-avg) + average gradient (s-avg) + skid resistance (μ) - 100m before the position of accident (accident type 011: run-off right on a straight lane, sample: 1951 accidents)

Portorož, Slovenia MARVin – Current Results “Similarity Search” Finding similarities in road geometry (simulation and search in the whole road network) … for Road Safety Inspection

Portorož, Slovenia MARVin – Current Results “Similarity Search” Finding similarities in road geometry (simulation and search in the whole road network) … for Road Safety Audit

Portorož, Slovenia MARVin – Current Results Visualisation of results (skid resistance, crossfall, gradient, accidents…)

Portorož, Slovenia Our goals… our commitment Our goals are: oExplanation of so far unexplored accident causalities oDemonstration of the connection of different parameters for accident sources using mathematical models oClarification of accident events on similar route sections oAccident analysis and crash-causes-research specifically regarding powered two-wheelers oInnovative accident prognoses and derived preventive measures

Portorož, Slovenia Our goals… our commitment We reach these aims by: oLinkage of the road conditions data with accident data based on the locality of the accident oDevelopment of suitable mathematical models for the verification of accident causalities oImplementation of accident-cause-research within Road Safety Inspections and Road Safety Audits oIdentification of connections between data on road accidents and traffic infrastructure and development of specific preventive measures oSpecific measures to create awareness in combination with driving education, based on detailed accident statistics and conclusions of accident analyses of motorcycles

Portorož, Slovenia Our Motivation…

Portorož, Slovenia THANK YOU FOR YOU ATTENTION!
