Safety

Safety is the principal design consideration. All designs have maximum safety as their objective.  

Environmental

Road designs should be made in accordance with the preservation of environmental status quo and environmental enhancement. A feasibility study of the environmental impact of the road must be done. Thus, road designers should work in line with environmental bodies for recent guidelines.  

Cost

Cost of construction

The economy of a road design without sacrificing other considerations is the designer‘s goal. Cost/benefit analysis may be used, when appropriate for considering the cost implication of a road design.   

Constructability

Here limitations on the construction methods, technology and materials should be considered. The designer should become familiar with construction practices and use the standard specifications for road and bridge construction. 

Maintenance

Maintenance work begins after the construction is completed. Insufficient or inappropriate design causes additional maintenance effort or may require further construction to correct the design flaw.
