Route Planning

We provide engineering advice on efficient and cost effective route plans, considering the selection of optimal structures and the preservation of roadside environments.

Route planning in dense area

Until now, the capital city has been built in densely populated areas. Therefore, there are technical know-how on planning, designing, and construction of road construction in densely populated areas making full use of this knowledge.

Plan considering road restrictions and construction congestion

In selecting the road structure, it is possible to plan based on land restrictions on construction and the influence on the flow of traffic during construction.

Evaluation of Road Development / Improvement

Traffic volume predicted based on the usage of highway and traffic characteristics. It is possible to evaluate each project of road development and improvement.
