Learnt operations are powerful and male lead to a beneficial or harmful situation depending upon the road user. We have seen in the previous points that the field of vision of the human eye is limited. Described below are the important road user characteristics studied in traffic engineering. There is therefore a need for an automated process to provide an objective assessment of the performance characteristics of road marking, such as wear and both day- and night-time visibility. Why are road user characteristics important in civil engineering? Every Road user has an initial particular motivation for traversing the distance. Safety could be more easily achieved if all vehicles had uniform dimensions, weights, and operating characteristics. We cannot standardise the intelligence of different people; everyone has different motivation, intelligence, learning and emotion. %%EOF Road-user characteristics : presented at the Thirty-first Annual Meeting, January 1952..
