Study of the Effect of Mixed Land Use on the Level of Service of Tukad Pakerisan Road Section Denpasar

Abstract

Roads are infrastructure intended for the movement of vehicles, people and/or goods in the form of roads and supporting facilities, while traffic is the traffic space for the movement of vehicles and people in road traffic space (Law No. 22 of 2009). Movement is formed due to activities carried out not in their place of residence, meaning that the relationship between spatial areas is very instrumental in creating travel and land use distribution patterns affect travel patterns, making a very close relationship between land use and transportation, where transportation as a benchmark in spatial interactions between regions and plays an important role in the development of a region, forming a land-use transport system (Tamin O.Z., 2000). Denpasar City as the center of activity in Bali cannot be separated from transportation problems such as traffic congestion and inconvenience like other big cities. Tukad Pakerisan Road, located in the South Denpasar area, is a two-lane two-way road, as an alternative link to and from the Denpasar city center gate, becoming a rapidly developing area in the last 5 years because this area has market activities, campuses, schools, culinary, residential, offices, and shops. The data used in this study consisted of primary data, where in collecting primary data, surveys were carried out, namely road geometric surveys, vehicle speed surveys, traffic volume surveys and side obstacles. Secondary data in the form of population data is obtained from the Denpasar City Statistics Agency in 2022. The data analysis method used is the Indonesian Road Capacity Manual (MKJI, 1997) and the Indonesian Road Capacity Guidelines (PKJI, 2014). Based on primary data analysis, it is found that Tukad Pakerisan road is an undivided two-lane two-way road (2/2 TT), primary environmental road function, length of section 1000 m, width of Rumaja 9 m, width of road body 7 m, width of kerb / shoulder 1 m, width of vehicle lane 3,5 m. The maximum traffic volume occurs at the afternoon peak hour of 11:00-12:00 am at 1889 skr / hour, high side obstacle class and commercial environment of 500-899 events per hour, free flow speed of 32.32 Km / hour. From the secondary data, the capacity value of the road section is 2208.1 skr / hour / lane, the degree of saturation is 0.68, the travel time is 0.04 hours, the instantaneous speed is 24.5 Km / hour, so that from the comparison of travel speed with the degree of saturation, the level of service of the Tukad Pakerisan road section is B, while from the degree of saturation value, the level of service has a value of C where the flow is stable but the speed of moving and moving vehicles is limited by traffic conditions, the driver is limited in choosing the speed.
