This work was a component of Mott MacDonald's Technical Assistance to Programmes of Highway Construction and Reconstruction co-financed by the European Bank and the Czech government.
The principal elements of the system – developed in association with the UK's University of Birmingham – are the HDM-4 model and a software interface between the model and the established Road Data Bank of the Czech Republic. This interface – called ADAPTOR –enables the user to easily create HDM-4 input files.
We conducted a major calibration exercise to adapt the HDM-4 model parameters to Czech conditions. This involved research into traffic, road user effects, road deterioration and climate data.
A standardised appraisal system was built around a set of default parameter files for the vehicle fleet, maintenance and improvement standards, speed flow curves, traffic flow patterns and climate zones. A standard methodology was also developed for appraising different types of projects.
A system manual was developed, comprising an appraisal guide, software users' guide and calibration guide. Users were trained at the University of Birmingham and in the Czech Republic.
