Abstract

Siliwangi – Walisongo road is a primary arterial road which connects the city of Semarang and Kendal. Siliwangi – Walisongo road. Siliwangi – Walisongo road is a track of “Pantura” which always crowded with traffic all the time. The density of traffic flow on the Siliwangi  – Walisongo road pose a high risk of accident on the road. Accident data from November 2012 till Oktober 2013 which obtained from Polda Jateng reports indicate that on the Siliwangi  – Walisongo road KM SMG 7+200 – KM SMG 8+100 there were 16 cases with 4 victims died and 13 were lightly wounded casualties. Based on the description above, it is necessary to analyze the accident on the accident prone area. This study begins by doing  library research and survey advances, then procced with collecting the secondary data and primary data. Primary data in the form of survey complatness infrastructure and road situations. Secondary data in the form of accidents on Siliwangi – Walisongo road KM SMG 7+200 – KM SMG 8+100, cross sectional and longitudinal images path, the data volume of the vehicle and the map of Siliwangi – Walisongo road. Method of analysis consisted of analysis of the relationship between variables, accident rate based on  distance and accident rate based on vehicle miles. The result showed, the volume of vehicles has a close relationship with a number of accidents that occur, the most influential factor of accident is the driver, and the driver’s lack of anticipation is the  largest  factor  of accidents. Accident rate based on distance resulted thah accident rate on segment 6, segment 13 and segment 16 exceeds the upper limit of the accident rate, while the accident rate based on vehicle miles, each segment doesn’t exceed the upper limit of the accident rate.

Abstract

Kendal regency as satellite city of Semarang has established a mutual relationship and completing each other. The economic development and population insde the rural area of Semarang and Kendal regency has raised up since the street of Jerakah - Mijen has been widened in 2004 - 2012. This can be seen during working hour in which Semarang - Kendal road was fully filled by vehicles especially motorcycle. Based on this, the research must be done to reduce the congestion that occurs around the Semarang - Kendal. This study aims to perform modal choice modeling with stated preference methods, so that the government can take better policies to support the operation of the BRT Semarang - Kendal route. The survey was conducted by spreading the questionnaire and interview that consist of socio-economic characteristic of the respondent, route characteristic, and questionnaire that is organized through stated preference technique with additional attribute namely, the margin of route cost and margin of time used of departure between motorcycle and BRT Semarang-Kendal route. Study sites were around the Semarang - Kendal and on the bus route Semarang - Kendal. From the research result, it is shown that the choice of vehicle is based on the margin of route cost, namely UBRT – USM = 1,2353 - 0,0007 (ΔX1). Meanwhile, the choice of vehicle based on the margin of time used is UBRT – USM = 2,61336 - 0,17441 (ΔX2). In addition, the choice of transportation mode based on margin of cost and time is UBRT – USM = 2,6683 - 0,7365ΔX1 + 0,00219ΔX2. The potential of the shifting of passenger from motorcycle to BRT based on the route cost is 74%. Whereas, based of time used is 50%, and 32% is based on both choices. In addition to modeling mode choice, we need to Traffic Demand Management (TDM) are both on regular lines Semarang - Kendal, because the fundamental purpose of building a BRT route Semarang - Kendal limited only to reduce congestion caused by the use of motorcycles in bulk.

Abstract

Sarang Weighbridge is one of the busy weighbridge that serve freight vehicles in the province of Central Java. With the large number of vehicles to be serviced will cause potential queues at the weighbridge. This study aims to determine the pattern of queues that occur at weigh stations and provide a recommendation to the appropriate queue system to be applicable to the Sarang Weighbridge, so it can increased the performance of the weighbridge.The method used to analyze queues in this study is the simulation method. This method is used because there are many variables at Weighbridge queuing system so it will be very difficult when using the methods of mathematical analysis. Simulation begins with field survey data. The data is used to perform the simulation and the results are then tested for compliance with the Poisson distribution . From the simulation results will then be made a better queuing models. Based on the analysis that we did, needed a better queuing system and the need to improve the infrastructure and human resources in order to better service on Sarang Weighbridge
