5.Element content in the road

Means road have different elements like curbs, lighting facilities, cycle tracks, pedestrian tracks, signal system it should be consider while designing of the road.

6.Traffic density and volume

Traffic density and volume survey of road is, done before designing and this data used for designing of various elements of road and duration of one phase of signals and traffic regulators, lanes of roads etc.

7.designing life of road.

Designing life of road should consider while designing of road and on basis of that materials should selected. Elements of road should design for fulfill need of future traffic volume. Traffic volume is forcasted by various methods.

8.Sefty of road users.

It is one of the prime consern keep in mind while design of alignment so before design of road various accidental studies done and conflict points also find out and after that designing of road is done.
