Abstract

Panjalin Intersection is a strategic four-leg junction connecting the Cirebon–Bandung national road with the Budur–Paningkiran provincial road in Majalengka Regency. Its unsignalized operation, intensive roadside commercial activity, and increasing peak-hour demand create recurring conflicts and unstable traffic movements. This study evaluates the existing intersection and develops a two-phase traffic-signal alternative using the 2023 Indonesian Road Capacity Guidelines (PKJI 2023) and PTV Vissim microscopic simulation. Primary data consisted of intersection geometry, seven-day classified turning-movement counts, vehicle speeds, and roadside-environment observations. Secondary data included population and road-status information. Under the existing condition, total demand reached 2,604 passenger-car units per hour, while the calculated capacity was 2,747.84 passenger-car units per hour. The resulting degree of saturation was 0.947, exceeding the PKJI design criterion of 0.85; the average intersection delay was 16.946 s/pcu and the upper queue-probability estimate was 71.63%. A two-phase signal plan with a 42-s cycle, 15.38-s green time for Phase 1, and 16.62-s green time for Phase 2 reduced approach degrees of saturation to 0.610–0.681, with an average of 0.649 and an average delay of 14.679 s/pcu. The Vissim scenario comparison also indicated reductions in average queue, maximum queue, stopped vehicles, and average travel time by 46.4%, 44.7%, 51.2%, and 21.7%, respectively. The combined analytical and simulation results show that installing a coordinated two-phase traffic signal is a technically reasonable short-term treatment, provided that signal timing, side friction, and queue development are monitored after implementation.

Abstract

In order to facilitate the movement of people from the place of origin to the place of destination, adequate transportation facilities must be fulfilled, both land, sea and air. In general, land dominates more to support these activities, such as railroads, which are one of them. The existence of this journal is to analyze the horizontal alignment of the 9.4 km long pari-kertical road section. At coordinate point X = 200180.40 ; Y = 9239557.46 and ends at coordinates X = 201072.18 ; Y = 9239177.37. From the results of the calculation of the horizontal alignment of the existing field data at a bend with a speed VR = 60 km/hour, the radius at the bend is Rc = 716 m, the value for Ls (transition curve) = 50 m, Ts = 621.76.
