SAFETY INDICATORS FOR ROAD JUNCTION TYPES. THE TRAFFIC HAZARD OF JUNCTIONS IN THE DUTCH PROVINCE OF UTRECHT, INSIDE BUILT-UP AREAS

KENCIJFERS KRUISPUNTTYPEN. DE VERKEERSONVEILIGHEID VAN KRUISPUNTEN IN DE PROVINCIE UTRECHT, BINNEN DE BEBOUWDE KOM

This report quantifies indicators for the safety of junctions in built-up areas in the Dutch province of Utrecht. They apply to traffic accidents causing injury and/or death, and accidents involving material damage only.Hazardous, slow-moving traffic was also studied. The following indicators were used in the calculations: (1) traffic hazard, divided into: (a) extent; (b) seriousness of consequences; and (c) into hazardous, slow-moving traffic; (2) traffic performance; and (3) junction type. This indicator is divided into: (i) principal form; (ii) traffic regulation; and (iii) into layout. By means of questionnaires, the data on the 'important' junctions were received from the local authority. The data were sifted, sorted and classified. The data ultimately produced 204 road junctions of the original 450 junctions. This number made it impossible to produce safety indicators based on an absolute classification of the selected features. For a number of junctions, cell data did not give sufficient information in order to arrive at valid conclusions. Six or more junctions are assessed on a combination of features in order to generate sufficient data per cell. This resulted in indicators in which intensity values were taken as the constant in expressing the extent of accidents and the seriousness of the consequences of an accident.
