dc.description.abstract Speed plays an important role in the justification of road infrstructure projects. It affects both vehicle operating cost and travel time cost. If incorrecr values for speed are used in the economic analyses of transport projects, incorrect investment decisions can result. This study was intended to verify the values for free-flow speed given in the look-up tables of programs CB-Roads by means of speed measurements on selected road sections. This report explains the speed experiment and gives the results. Information from other studies was used to supplement the study results in developing a matrix of free-flow speeds similar to that used in previous versions of CB-Roads. en
