Traffic chracterstics Physical, Mental, Psychological, Environmental

Physical : The physical characterstics of the road uses may be either permanant or temporary. The permanat characterstics are the vision, hearing, strength and the genral reaction …

The traffic engineering studies carried out for collecting traffic data are also called traffic surveys. Traffic engineering studies are carried out to analyse the traffic characterstics and their movements along the identified roads. The different traffic engineering studies generally carried out are 1. Traffic volume studies 2. Speed spot studies …

Speed spot studies : One of the earliest methods for determining spot speed of a vehicle is by finding the time taken to cover a short distance of say 15 or 30 m. The selected distance may be marked on the pavement surface and the time taken ( t sec …
