Abstract

Public Transport is one of the solutions to resolve the traffic in urban area, particularly in Semarang City. Therefore, Semarang City Government provided the public transports in the form of Bus Rapid Transport (BRT) Corridor I (the route of Mangkang – Penggaron) and Corridor II (the route of Ungaran – Terboyo Bus Station). According to the service performance evaluation to BRT Corridor I by Adyan and Salman in 2012, it was found that the Load Factor was 44,73%, and it did not meet the standard of PP.No.41/1993 and SK. Dirjen no.687 stating that the minimum load factor is 70%. Though the service provided was better than other public transportation. Therefore, an evaluation is required to the service performance on BRT Corridor II to determine whether BRT corridor II has the same problem as BRT Corridor I and how the solution to be used as a reference to the next corridor. This research applied the methodology of Dynamic Survey on BRT, Static Survey, Origin Destination Survey and Home Base Survey. Based on the survey and analysis results, it was obtained that the Load Factor by 23.51% is below the standard. In conclusion, the service performance of BRT Corridor I and BRT Corridor II was experiencing the same problem from the aspect of efficiency and effectiveness which is in accordance with the applicable standards but it was found in the field that the load factor was less than 70%. Based on the Home Base Survey, the non-users who are around BRT Route suggested that the manager should be more intensive in socializing BRT to communities and pay attention on the punctuality of BRT travel time. There are still a lot of transport other than BRT operating on the same route, which also resulted in a lack of BRT Load Factor because people tend to choose the transport that can stop anywhere, and it is in contrary with the purpose of the Public Transport. The researcher suggested that BRT and public transports other than BRT are under one management in terms of all the transportations stop in the shelters and have the same service standard. According to survey and analysis, Route from Ungaran to Pemuda and Raden Patah to Ungaran use BRT, whereasPemuda to Terboyo and Terboyo to Raden Patah use feeder transport in other to minimalize cost and make time around become quick, and according to analysis load factor from corridor I and II, prove BRT not too effective presents in Semarang City.

Abstract

Along with the increasing demand and growth of population, the more necessary a good transportation to smooth traffic flow. Especially KA demands will increase service capacity, speed, and safety and comfort, it is necessary to thinking or planning that address these issues, including the improvement of facilities and infrastructure such as the construction of double track Railway network. In this case only a segment of Semarang Tawang Railway track-Ngrombo are supposed to represent the path Bojonegoro Semarang. Stages of the methodology used in the planning stage consists of the problem formulation, literature review, data collection, data analysis, planning, RAB and the final stage. The change capacity plans that will be served by this pathway, leading to the condition of the existing track alignment and structure must be adapted to the requirements for Class I. path Based on the soil conditions on the project which is unstable and track existing conditions that are often submerged rob the new double track line is designed with a higher elevation than the existing track conditions. From the analysis it can be seen that almost all double track line has a condition that is much different from the existing track in terms of structural, alignment and land protection. Calculation results obtained from this project spent Rp 457.000.000.000,00 to build the new track.

Abstract

Faculty of Public Health is one of faculty in Diponegoro University which is inseparable from parking problems. Due to increasing the number of students and vehicles ownership, the parking space requirements are exceed its capacity. To determinate the parking space unit (SRP) using Pedoman Teknis Penyelenggaraan Fasilitas Parkir,1996. Current parking capacities based on SRP are 242 vehicles for students motorcycles, 37 vehicles for cars, and 32 vehicles for employees and lecturers motorcycles. Parking space requirements based on the survey results and analysis are 360 vehicles for students motorcycles, 18 vehicles for cars and 36 vehicles for employees and lecturers motorcycles. To reach the parking demands, it shall need several steps of optimization. The first  step is  rearranging parking configuration based on parking space requirements according to survey results. After parking configuration setup, parking space requirements have not been fullfilled. The second step is class rescheduling. Its needed in  order to get optimal parking demands. After class rescheduled, parking space requirements for students motorcycles became 310 vehicles. To solve the problem of parking space requirements which exceed its capacity, it is necessary to restructure or change the configuration of the parking supplies in an optimal order capacity of parking spaces to serve the parking demands. Optimize the configuration of parking spaces by changing the functionality of some of  cars parking to motorcycles parking thus the parking space being adequate.

Abstract

Semarang city as a big city develop rapidly as centre business, trade, and government in Central Java faced with transportation problems such as traffic congestion caused by the volume of road vehicles with the road capacity is not balanced. The result of analysis of existing conditions with reference, Bangkong Intersection dominant currents in the western and eastern approach that shows the performance of intersections with an average degree of saturation 1,218  that means in excess of the ideal number. In the eastern approach Bangkong Intersection in the peak of morning, afternoon and evening, long queue reached 95 m, 219 m, and 219 m. To value the average intersection delay 62.46 sec/smp , 235.24 sec/smp, and 137.68 sec/smp. While in Milo Intersection, average DS values 1,100 that means in the excess of the ideal number. Long queues at the eastern approach Milo Intersection in the peak morning, afternoon and evening is 108 m, 242 m, and 242 m. To value the average intersection delay with a value of 36.99 sec/smp, 65.39 sec/smp, and 108.16 sec/smp.To get the operation optimization Simpang Bangkong and Milo made simulations by showing 3 scenarios. It was made the scenario 1 is the green time adjustments resulting DS same value in every second approach the intersection. Scenario 2 is to change LTOR into LT with the result being a greater capacity, the DS becomes small, a larger queue length, and delay be small. Next, scenario 3 is made by changing into a one-way system. Here after devised scenario 3, is one way system to produce a DS value becomes smaller, a small queue length, delay values are relatively larger. For QL values obtained Bangkong Intersection 44 m, 40 m, and 99 m. the average of intersection delay values 46.88 sec/smp, 38.27 sec/smp , and 40.74 sec/smp.  For Milo Intersection, the value of QL is 27, 15 m, and 18 m. Value of the average intersection delay 8.81 sec/smp, 32.60 sec/smp , and 7.61 sec / smp. The results of the analysis with 3 scenarios show that one way system scenario has better performance with consideration of this scenario prioritize large traffic flow from west to east and toward the opposite.

Abstract

Soedarto Roundabout is an icon of Engineering Faculty Complex in Diponegoro University. Tis roundabout becomes a potential location for traffic violations, as it is shifted from the existing junction. Some travellers use it as a shortcut route therefore the traffic performance decrease. Thus, it is necessary to design some alternatives to increase the performance and traffic order. This study aims to identify the traffic characteristics in roundabout area, design some alternatives of intersection management, and determine the best alternative proposal. The quantitative method used in performance analysis of roundabout and the surrounding road network is based on Indonesian Highway Capacity Manual (MKJI, 1997). The qualitative method used is the Analytic Hierarchy Process (AHP) Method. The result shows that traffic order level in this area is quite low, due to many violations caused by the shortcut movements. The number of violation increase in off-peak time. The Degree of Saturation value (DS) of Soedarto Roundabout is 0.88, and the DS of Peternakan Intersection is 0,93. Three alternatives of intersection management in Soedarto Roundabout Area are the change of roundabout and median geometric into priority intersection, chanelization, and roundabout blocking. The quantitative analysis shows that the performance of the third alternative is quite good, with the DS of weaving area between Soedarto Roundabout and Peternakan Junction is 0.70, and the DS of Peternakan Junction is 0.83 (after extended). Thus, the qualitative analysis using AHP shows that the third alternative is the best.

Abstract

An Electronic Toll Collection (ETC) system can be used to reduce vehicle queues in toll gates. This study aims to determine the most effective combination of conventional and ETC booths in a toll gate. The Pondok Gede Timur toll gate was selected as a case study for this research. The results show that vehicle flow did not linearly affect the vehicle lost time since the fluctuations of vehicle flows were significantly different from one day to another. The application of ETC system could reduce the queue length, both in conventional and ETC booths located in a toll gate.Keywords: conventional toll booth, ETC booth, lost time, and queue length.

Abstract

The Intersection between railway crossings with roads have any problems, especially when the railway gate were closed while trains pass. The problem is the queue of vehicles and the time of vehicle back to normal before the crossings opened. Geometric of Kaligawe Road is 4/2D with all types of vehicles and Kaliwungu is 2/2UD dominated by light vehicles. Both are in the class of primary arterial road. The data was collected by surveying directly at the two railway – roadway crossing at peak hours in the morning, afternoon, and evening. The data were taken during the normal flow is the flow rate (flow) vehicle, traffic speed, road geometric, and a long stream of vehicles crossing back to normal when the railway gate is opened. Meanwhile, when the railway gate is closed is the speed of shockwave, railway gate closing time, and a queue of vehicles. The data was then analyzed using the shockwave method, the capacity of the road using Highway Capacity Manual guidelines (MKJI) 1997 and theoretically Greenshields models are then compared the results, in order to obtain the queue length and time of return to normal road traffic due to the effect of the closure of crossings when trains pass. The results of analysis on the existing condition at Kaligawe Semarang and Kaliwungu Kendal still able to accommodate vehicular traffic passing through the intersection, because based on Timetabling 2013 +72 recorded trains pass each day with a headway of trains in peak hour morning, afternoon, and evening the average is 22 minutes if the closure 3-4 minutes. For Kaligawe Road if closure (t) = 3 minutes long queue gained = 0.15 to 0.25 miles with vehicles back to normal after crossing when the door is opened (t2) = 3.913 to 5 minutes, and if t = 4 minutes queue length obtained = 0.2 to 1.66 km with t2 = 5.21 to 6.68 minutes. While on the Road Kaliwungu if t = 3 minutes obtained queue length = 0.078 to 0.366 km with t2 = 4.172 to 11.88 minutes and if t = 4 minutes obtained queue length = 0.105 to 0.5 km with t2 = 5.564 to 15.85 minutes. t2 obtained in Jalan Kaligawe and Kaliwungu still less than 22 and 25 minutes. Responding PT.KAI plan which will operate a double track to increase the frequency of trains ± 72 to ± 200 trains per day. Based on the assumption that the headway of trains is the same every hour it is 7.2 minutes, then the results of the analysis for the Kaligawe road still able to accommodate traffic in the event of the closure 3-4 minutes, but for the Kaliwungu are no longer able to accommodate traffic flow if the closing 3 and 4 minutes because t2 obtained is 11.88 and 15.85 minutes. Besides, the degree of saturation (DS) in Kaligawe road = 0.401 and Kaliwungu = 0,747, to get for good traffic performance, for Kaliwungu Road becomes necessary to change the geometric 4/2D. The results of these observations can be useful in making policy considerations relevant to the response effort DEPARTMENT PT.KAI operate the double track in 2014 in order to maximize the performance of the Road Traffic Road Kaliwungu Kendal and Kaligawe Semarang.
