Emergency stop lane design on national road in West Sumatra (case study: Panorama 1 Sitinjau Lauik)

Abstract

West Sumatra Province has geographical conditions consisting of lowlands and highlands. These geographical conditions certainly affect the geometric conditions of the road, especially on the Panorama 1 Sitinjau Lauik National Road Section. One of the factors that cause accidents is a vehicle that has failed brakes. This study aims to calculate the length of the emergency stop lane; plan the structure of the building; and plan a modeling design. The results of the Emergency Stop Route Design research showed that the overall dimensions were 240 m. Preliminary design results are as follows: Beam (600 mm width and 1100 mm height), Amount of flexural reinforcement: Compression reinforcement 8 D – 25 mm; Tensile reinforcement 4 D – 25 mm; Amount of shear reinforcement: Area of support 2Ø13-100 mm, Area of field 2Ø13-150 mm. Cross beam width 300 mm and height 600 mm. Amount of flexural reinforcement: compression reinforcement 3 D 16 mm; Tensile reinforcement 3 D 16 mm. Number of shear reinforcement: Support area 2Ø13-100 mm and field area 2Ø13-150 mm. For longitudinal reinforcement, the diameter is ø10 – 200 mm, the tie reinforcement has a diameter of ø10 – 200 mm and the vertical reinforcement has a diameter of ø16 – 150 mm.
