Abstract

The geometric design of the road Wirosari Semarang to Ungaran road section, which is in the city of Semarang, is one of the infrastructures to provide proper road access with optimal travel time. With the division process, the government must provide proper road access with optimal travel time so that the community mobilization process can run smoothly. The research objective is to plan the geometric shape of the road according to the applicable requirements to provide safety and comfort for road users. The Highway Road Geometric Rule method and visualization using AutoCAD® 2D are used. The results of the geometric planning of the road are obtained with a design speed (Vd) of 60 km/hour, a planned road width of 2 x 3.5 meters, and a road alignment with a horizontal curved Spiral Circle Spiral with a radius of 318 m is formed. Meanwhile, the vertical alignment obtained a concave arch type with a length value (L) of 53.28 m

Abstract

In today's globalized world, much software is developed to make work easier to implement. This software is demonstrated using AutoCAD Civil 3D® to demonstrate how geometric road design can be completed briefly. In this case, the purpose of geometric planning is to evaluate the effectiveness of manual geometric planning using AutoCAD Civil 3D®. This journal's geometric road planning implements qualitative methods. The geometric planning of the road that became the subject of this journal's research is located on Jalan Kertawangunan - Kadugede, with a road plan length of 9.3 km as an additional alternative to Kuningan Regency's new outer ring road. The calculation of horizontal alignment required the minimum bend (Rmin) and transition arch (Ls) values. Therefore, it is necessary to plan the assembly ahead of time before planning the corridor. The corridor's function is to determine the location of cut and fill based on road planning. As a result, planning a path with AutoCAD Civil 3D® is more effective and efficient, and it can retrieve the necessary data quickly. There are four points of interest with different types of curves in road traffic planning. The plan speed (Vr) was set to 60 km/h, the maximum superelevation slope (e-maks) was set to 0.08, and the transverse friction coefficient (f) was set to 0.153. The average excavation volume obtained from this planning is approximately 1,900,000 m3.
