ODIMAST - Optimization of connection points in terms of capacity and traffic safety

Interchange ramp terminals of the Austrian motorway and major highway network were grouped in typical interchange types and classified by capacity and safety. A mix of two methods was used for this cluster exercise. Statistical data mining of cross sectional counts and analysis of three case studies were used to find clusters. As a result a sheet with the major characteristics of interchange ramps, grouped in exits and entrances ,describes the findings for standard applications.
