Abstract

Abstract This study aims to determine the performance of the unsignalized intersection Jl. M. Kahfi II – Jl. Srengseng Sawah, South Jakarta. The analysis of the performance at unsignaled intersections refers to the guideline of the Indonesian Road Capacity Manual (MKJI), 1997. Data obtained through field surveys include geometric conditions, environmental conditions, and traffic conditions. The results of the analysis show that the peak hours of the working day in the morning period occur at 06.30 – 07.30 with a degree of saturation (DS) 1.10 with an intersection delay (D) of 25.16 sec/pcu and the afternoon period occurs at 18.00 – 19.00 with a degree of Saturation (DS) 0.93 with Intersection Delay (D) 16.39 sec/pcu. The results of the analysis for holidays show that the peak hours of the morning holiday period occur at 08.00 – 09.00 with a Degree of Saturation (DS) 0.71 with a Intersection Delay (D) 11.74 sec/pcu and the afternoon period occurs at 16.45 – 17.45 with a degree of saturation (DS) 0.85 with an intersection delay (D) of 14.31 sec/pcu. The results of this analysis indicate that the performance of the unsignalized intersection on Jl. M. Kahfi II – Jl. Srengseng Sawah South Jakarta is already in bad condition on weekdays and not good on holidays.. Increasing the capacity of Jalan Kahfi II in accordance with detailed spatial plans and zoning regulations in the Jagakarsa District, South Jakarta City in 2014, namely an increase in Jl. Kahfi II from Road Type 2/2 UD to 4/2D is very urgent to apply Keywords: traffic performance, urban, unsignalized intersection

Abstract

ABSTRACT This research discussing about decision support system analysis in determining concrete and composit road construction compared to asphalt construction for the case of roads in North Maluku Province. This study uses the Analytic Hierarchy Process (AHP) method or model as a method to analyze the feasibility of concrete and composit construction compared to asphalt construction. There are at least 7 (seven) factors that are considered as AHP inputs, namely road conditions, technical pavement, ecomonical/cost, duration/method of construction, availability of equipment, environmental conditions, and availability of materials. This study method includes data collection and analysis methods. For data collection, this study uses a questionnaire method that contains questions related to technical and non-technical factors that are used to assess the feasibility of a road for selecting a type of road pavement with flexible or rigid pavement. The construction feasibility of concrete and composite pavements is better than that of flexible asphalt pavements on road constructions, with the following sub-criteria conditions; roads that have bends and inclines, lower road maintenance costs, excellent weather and environmental resistance, less dense traffic, easy work execution and can be done at any time, do not require a lot of AMP and equipment, and asphalt availability can't fast time. The alternative of road pavement type is effective as a weight value of 33.78% with using the composite pavement construction.
