| dc.description.abstract | Yogya-Solo routes as one of the lines connecting Yogyakarta-Klaten-Solo can not be separated from traffic issues. There are two intersections around Prambanan Temple within 436 meters distance at Yogya-Solo routes. The distance of these intersections is short and the volume of vehicles that pass the road is too high so it will cause problems. That problem occurs because there is no signal coordination between Stasiun Brambanan intersection and Taman Wisata Candi, that can cause traffic jam on peak hour. Therefore, it is needed for alternative improved coordination between the two intersections signals to solve traffic congestion during on peak.
This research is using traffic microsimulation VISSIM software in order to create delay analysis in the existing condition and signal coordination planning. Primary data are compiled according to direct observation in Yogya-Solo routes, to obtain condition volume of existing period in peak hour and off peak hour in which will refer in the planning of new cycle time by observing coordination theory.
From the analytical result, it is known that both of intersections in Yogya-Solo routes need better arrangement. The route from West-East with average delay of 31.96 seconds, average travel time 57.24 seconds and average traveling speed 27.42 kilometer/hour and service level E in peak hour period. Therefore, better improvement is needed to coordinate signal between the intersections, by determining same new cycle time for those intersections. From three of the plans in peak hour, it is known that the best alternative is cycle time 117 seconds, and average delay 17.65 seconds, travel time from West arm at 2nd intersection onto West arm at 1st intersection (West-East section of Yogya-Solo Routes) by 50.99 seconds, average travel speed 30.78 kilometer/hour in service level E. Travel time from East arm at 1st intersection onto East arm at 2nd intersection (East section of Yogya-Solo Routes) by 31.73 seconds, delay of 15.57 seconds, average travel speed 49.47 kilometer/hour in service level E. On off peak hour period, from the result of analysis, it is obtained that average delay of 19.59 seconds, average travel time 39,6 seconds and average speed 39.64 kilometer/hour in service level E. From three of the plans in off peak hour, it is known that the best alternative with new cycle time 98 seconds, and average delay of 16.42 seconds, travel time from West arm at 2nd intersection onto West arm at 1st intersection (West-East section of Yogya-Solo Routes) by 30.77 seconds, average travel speed 51.01 kilometer/hour in service level D. The travel time from East arm at 1st intersection onto East arm at 2nd intersection (East section of Yogya-Solo Routes) by 27.25 seconds, delay of 14.83 seconds, average travel speed 57.60 kilometer/hour in service level D. | en_US |
