Alternative Title
3D Road Simulation for Evaluation of Road Design
Abstract
Two dimensional road design is connoting danger factor because different point between design standard and driver's reaction. It is difficult to expect visual effect by limit of two dimensional road design. Consequently two dimensional road design is difficult to recognize problem that happen beforehand when achieve business. Therefore three dimensional road design that can grasp problem after completion is required.
In this study, three dimensional road was designed to evaluate road that is designed. Road designed by Inroad that is road design program. DTM is created using digital map and elevation data. And road designed in DTM. Three dimensional road was designed by integrated DTM of road and topography.
Design estimation performed in three dimensional designed road. Driving simulation and stopping sight distance assessment was enforced to estimate stability of alignment. Shadow simulation was executed for abstraction section of icy road surface.
As a result of estimation, this study could confirm shape of road after completion. And could calculate and visually confirm stopping sight distance. Also, section of icy road surface is abstracted by shadow simulation.
