Abstract: This is other approaches and methods of using solar photovoltaic technology on highways, for example, using solar-powered LED roadway lighting, security lighting, highway changeable message, etc. Although these are very important applications, in terms of power generation or power saving, they are almost negligible in comparison to the approach that it has suggested in this paper. Also, one can see the cost-oriented modeling and design optimization for alignment to determine operation and engineering cost of the highway.

Keywords: solar, LED, cost-oriented, optimization.
