Performance Study of the Weleri Ring Road Intersection in Central Java

The Weleri ring road intersection is a signalized intersection that connects the Weleri ring road, the district boundary road. Batang – Weleri, the central main highway, and the Weleri toll gate. The purpose of this study was to analyze the performance of the Weleri Ring Road Intersection in terms of capacity, the degree of saturation of delays, and the length of the queue based on the Indonesian
Road Capacity Manual (MKJI, 1997), knowing the traffic growth of the Weleri Ring Road Intersection in the next 10 years from the first year. 2022 using the geometric formula method and providing alternative solutions to overcome the degree of saturation, delays and long queues at the Weleri Ring Road Intersection. The procedural framework used in this study starts with identifying the problem followed by collecting primary and secondary data, then processing and analyzing the data and drawing conclusions and suggestions from the results of the analysis. The results of the data analysis obtained the degree of saturation for each approach as follows: the north approach (towards the Weleri ring road) is 0.77, the south approach (to the Weleri toll gate) is 0.65, the east approach (towards Weleri District) of 0.70, and the western approach (towards Batang district) of 0.51. According to the results of geometric calculations, the growth of vehicles during the evening rush hour at the Signalized Four Intersection of the Weleri Ring Road increases annually by 1.34%.
