Abstract

The queue that occurs at U-turn is affecting its performance decreases of urban road performance. The maximum length of queue on Dr.Ir.H.Soekarno Street, Surabaya which is 102 meters decreases its performance. The Simulation is based on Poisson distribution using the arrival rate (λ). The time that used to turn is using formulation of cumulative frequency distribution of the time to turn. The result of the simulation was corrected by correction factor that add it to the turn time. The result of the simulation is length of the queue that is used on the analysis of road performance. The result of analysis is the maximum length of queue is 102 meter with the correction factor is 0.9 second. The capacity of weaving C is decreases from 3960 pcu/h to 3858 pcu/h and the decrease of V/C ration from 0.77 to 0.79 is caused by the length of the queue. In order to reduce the effect of queue is by expand the road width from 8 meter to 11.5 meter. In this condition, the capacity could increase from 3496 pcu/h into 5113 pcu/h and V/C ratio from 0.88 into 0.60.

Abstract

Retaining wall is one of the reinforcing techniques used to control soil movement. Reinforcement with retaining walls is relatively expensive so an efficient design is needed. Unfortunately, the guidelines for planning a retaining wall are limited. Analysis of design criteria was carried out on silt clay soil taken in the area of the Karang Joang Kalimantan Institute of Technology (ITK) area based on the dimension guide given by Hardiyatmo (2010) and Nakazawa, et al (1980) for safe slope height based on the type of retaining wall. The minimum criteria for cantilever type retaining walls with a slope height of 2-3 meters is the width of the TOE (A) = B / 3 meters, the base width retaining wall (B) = minimum of 0.7 H meters, the width of the upper wall (C) = 0.2 meters and wall thickness (D) = H / 10-H / 12 meters, while for slopes with a height of 4- 5 meters the safe dimension range is TOE (A) width = A / 3, slope width (B) is designed to be a minimum of 0.9 H meters, width of the wall (C) = minimum 0.2 meters and wall thickness (D) = H / 10-H / 12 meters. Gravity retaining wall has design criteria for slopes as high as 2-3 meters of A = D / 2-D meters, B is taken to a minimum of 0.7 H meters, a minimum C value of 0.3 m and D of H / 8 - H / 6 meters for slopes with a height of 2-3 meters, meanwhile for slopes with a height of 4-5 meters, B to a minimum of 0.9 H meters, with a value of A = D / 2-D meters, the C value is designed to be a minimum of 0.3 meters and D = H / 8 - H / 6 meters.
