EVALUASI JALAN LINGKAR UTARA SURAKARTA DITINJAU DARI PERILAKU PEMILIHAN RUTE

Abstract

The objective of this study is to evaluate of Ring Road Development seen from the behavior of passenger car in Surakarta in choosing between north ring road and arteries route with logit binomial model. The dependent variable needed are journey time and cost. Data were taken by recording the number of vehicle and journey time on Monday, Tuesday, Wednesday, and Saturday started at 06.00 am – 18.00 pm. Then, data were analyzed to find the correlation among the proportion of route choice, headway, and journey cost with regression in three traffic flow: west to east, east to west, and both. The study concluded that the passenger car from west to east traffic in peak hours tends to choose ring road, while from east to west traffic in peak hours of afternoon tends to choose arteries road because of some reasons namely any necessity in city, landscape factor, and geometric intersection. The car passengers of Surakarta vehicle number on Saturday in peak hours tend to choose ring road, and choose artery road in off-peak hours. The car passengers of non-Surakarta vehicle number on Saturday in both peak hours and off-peak hours tend to choose artery road because some reasons i.e. there is no delay, time is not priority, and there is chance to see city. The representative logit binomial by choosing journey time and operational vehicle cost variables is model while route probability of route A or ring road at headway and journey cost is zero. The existence of north ring road is highly needed and traffic average speed in ring road should be increased. It is recommended that the plan and design of corridors of north ring road are needed in order to reach the aim of the development of ring road as speed traffic with average speed fitting with the speed design of ring road. The unique buildings and environments as Surakarta’s characteristic should be maintained and spots of bad services are removed.
