Easy community life, both in terms of economic, social, educational, and others, is the purpose of designing and constructing access roads or connecting roads. In addition, road design must consider safety aspects to achieve safe, balanced, and sustainable road performance. In this study, a manual horizontal alignment road design was carried out to link the road of Jalan Plupuh Tanon and Jalan Gabugan Sragen Section 1 from STA 0 + 000 to STA 2 + 257,221 with the planning of three bend points guided by Highway Design Standard of Indonesia 2021. Primary data in the form of coordinates and contours are taken from Google Earth and the Global Mapper. The design starts by managing primary data and calculating the elements that make up the horizontal alignment so that a road with a design speed of 30 km/h is obtained, the value of e = 8%, and a radius of 200 m. Three horizontal alignment points use a Spiral-Circle-Spiral (SCS) arch with an intermediate curve (Ls) value of 38 m and a circular arch (Lc) of 44.229 m, respectively.

Highways are needed because they are the most widely used transportation infrastructure to support the economy and daily human activities that function to pass traffic on it quickly, safely, and comfortably. In today's world of rapid digital improvement, road planning using AutoCAD Civil 3D® results in a more efficient, accurate, and time-saving road planning process than road planning using manual methods. The horizontal alignment of the road determines the location of the road in question. The horizontal alignment has three geometric components: tangent, curve, and transition between straight line and arch. The purpose of writing this paper is to plan the geometric road on the North Ring Road section Jalan Garuda - Jalan Moh. Hatta in the northern area of Tasikmalaya, West Java. The road is planned to add land transportation facilities and connect the Cibeureum District - Cipedes District. The length of the road section is 1016 m or 1,016 km (STA 0+000 – STA 1+016.79).

Highways are the central infrastructure that supports land transportation. Therefore, the highway strongly supports various activities and human needs in land mobilization so that it can achieve its goals both in economic and non-economic terms. In particular, on some highways, there is a system that divides the road into two special lanes: the frontage road and the fast lane. This study aimed to assess the effectiveness of the frontage road on Jalan Margonda Raya, Depok. The data retrieval method is to survey directly and retrieve data through CCTV during peak hours on the road. From the results of this study, the average speed of a motorcycle is 26.625 km / h, which is below the standard free current speed based on the 1997 MKJI of 32.64 km / h, while the average speed of light vehicles (angkot) is 9.9375 km / h, which is below the standard free current speed based on MKJI 1997 which is 41.48 km / h and also obtained a saturation degree value of 1.1105 which means that the frontage road on Jalan Margonda Raya has a Level of Service F value. Therefore, it can be concluded that the frontage road on Jalan Margonda Raya has conditions of forced current, low speed, volume above capacity, and long lines (traffic jams).

Along with the development of the industrial sector in Indonesia, Karawang has excellent opportunities and potential to develop in this field, where Karawang currently has congestion problems from and towards industrial estates in a certain period. The geometric planning of the access road to the Jakarta-Cikampek Toll Road aims to provide references and preliminary designs to unravel the congestion problem. Systematic calculations and integrated visual depictions of AutoCAD Civil 3D® software assist the geometric design process of such roads. The research method used is quantitative. The necessary data sources are obtained from observation methods, literature studies, and primary data. Planning begins with determining the design criteria of the purpose and the function of such roads. Then the design criteria are used as a reference to determine variables in horizontal and vertical paragraphs. From the results of horizontal paragraph planning, one arc of FS (Full Circle) and 2 SCS (Spiral-Circle-Spiral) were obtained. Then the results of the vertical paragraph design got two concave arches.
