Idea of MARVin

Road conditions(RoadSTAR*) Accident data

Linked by the locationof accident

*Road Surface Tester of arsenal research

Portorož, Slovenia

Idea of MARVin

Combine detailed information on:

o Road Geometry (horizontal curvature, gradient and crossfall),

o Road Surface Condition (roughness, rut depth, texture depth

and skid resistance)

o and Road Accidents.

Portorož, Slovenia

RoadSTAR – Road Condition Monitoring

o Skid resistance

o Texture (cracks)

o Transverse evenness (ruts)

o Roughness

o 250.000 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

o Curve radius

o Transverse slope

o Longitudinal slope

o Actual longitudinal profile

o Registration of lane(Possibility of creating route graphs)

Portorož, Slovenia

MARVin – Road Safety Analysis

o Visualisation and elaboration of road condition data with

arSis (arsenal research road information system)o Correlation with road safety datao Prognosis of scenes of accidento Accident preventiono Reconstruction expertise,

reconstruction plans

MARVin – Current Results

Visualisationof results

(skid resistance, crossfall, gradient, accidents…)

Portorož, Slovenia

Our goals… our commitment

Our goals are:o Explanation of so far unexplored accident causalitieso Demonstration of the connection of different parameters for

accident sources using mathematical modelso Clarification of accident events on similar route sectionso Accident analysis and crash-causes-research specifically

regarding powered two-wheelerso Innovative accident prognoses and derived preventive

measures

Portorož, Slovenia

Our goals… our commitment

We reach these aims by:o Linkage of the road conditions data with accident data based on the

locality of the accidento Development of suitable mathematical models for the verification of

accident causalitieso Implementation of accident-cause-research within Road Safety

Inspections and Road Safety Auditso Identification of connections between data on road accidents and

traffic infrastructure and development of specific preventive measures

o Specific 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!
