The above process is recently incorporated in H12 road design software [23], used by many engineering firms in Greece for road designing, and applied for the assessment that follows.
On one hand, they should abide to local regulations for the road design process and the road safety management, if relevant.
The design guides considered are the AASHTO Pavement Design Guide (for flexible and rigid pavements and for low-volume road design), the Asphalt Institute Pavement Design Guide, the Mechanistic-Empirical Pavement Design Guide (MEPDG), and the Portland Cement Association (PCA) [56 59].
A number of intersection design problems for older drivers were identified and recommendations for changes in road design features and traffic management practices that have the potential to reduce crash and injury risk for older drivers at intersections are made.
This study implements a methodology for configuring VR simulation functions and develops a VR system for optimising the road design data.
By employing our method, the clothoid curve and its offset can be efficiently incorporated into CAD/CAM systems, which are important for the development of 3D civil engineering CAD systems, especially for 3D highway road design systems.
