Abstract

Abstract The weakness of mode choice model based on trip-based and tour-based is not paying attention to how the characteristics of the activity  influence the alternative modes used to conduct such activities. Regarding this, the mode choice model in this study based on the activity schedule and the time allocation. The mode choice model for the three alternatives such as private car, private motorcycle and other modes in this study is developed with the multinomial logit choice model based on the utility time allocation model of activity choice in a day. The selection mode is used to conduct the activity choice at the time after returning home from working activities.The result of the empirical analysis shows that the attributes of individuals, families and activities greatly affect the utility of time allocation of activities such as sports, shopping, meetings, entertainment and socialisation. Alternative modes that have greater attributes of utility activity value, shorter travel time, lower travel costs and joint tour have greater chance to be selected. Keywords: Activity time allocation, Activity Timing, Mode choice, Utility time allocation, Multinomial Logit   Abstrak Kelemahan model pemilihan moda berdasarkan trip based dan tour based adalah tidak memperhatikan bagaimana pengaruh karakteristik aktivitas terhadap pilihan moda yang digunakan untuk melakukan aktivitas tersebut. Berdasarkan hal tesebut, model pemilihan moda dalam penelitian ini dibuat berdasarkan  jadwal dan alokasi waktuaktivitas.Model pemilihan moda untuk tiga alternatif pilihan mobil dan motor pribadi serta moda lainnya dikembangkan dengan model pemilihan multinomial logit berdasarkan model utilitas alokasi waktu aktivitas pilihan dalam satu hari.Pemlihan moda digunakan untuk melakukan aktivitas pilihan pada waktusetelah pulang ke rumah dari aktivitas bekerja.Hasil analisis empiris menunjukan atribut individu, keluarga dan aktivitas sangat mempengaruhi utilitas alokasi waktu dari beberapa aktivitas pilihan seperti olah raga, belanja, meeting, hiburan ke mall dan bersosialisasi.Alternatif moda yang mempunyai atribut nilai utilitas aktivitas yang lebih besar, waktu tempuh yang lebih singkat, biaya perjalanan yang lebih rendah dan bersifat joint tour menpunyai peluang yang lebih besar untuk dipilih.

Abstract

Muara Enim road segment SP. Sugihwaras very potential to occur landslide based on its location which is on the edge of the river. Recorded by the National Road Implementation Institute (BBPJN) III has been a slope grid in 2014. Slope improvement efforts undertaken by the Ministry of Public Works using a combination of gabion not too successfully overcome the problem. In addition to the strength element of a construction work, the cost and timing of the implementation are also important considerations in planning. Slope at 173 + 535 - Km 173 + 705 along 170 m using soil nailing planned three nails with 19 mmnail diameter and angular slope of 20° with variation of nail length, nail installation spacing, safety factor (SF) and estimated working time to the cost. Using the SPSS.16.0 program, the variations are modeled by nine samples as multiple linear regression equations. Based on the SPSS output, then tested the classical assumption and feasibility test model which produced the model: Cost (million) = - 3159,475 - 54,097 length - 1354,256 distance + 5188,127 SF + 26,483 time. The Budget Plan (RAB) covers preparatory work, drainage system, soil nailing, and shotcrete. An efficient cost estimate of 8 m length nail, 1.5m installation distance, 1.5 safety factor and 64-day working time resulted in a cost of Rp. 3.853.485.500,00 (Three billion eight hundred fifty three million four hundred eighty five thousand rupiah).

Abstract

Tengkuruk Permai street is currently used for city transportation terminals, on street parking, access and exit to 16 Ilir market parking lot (off street parking), entrance to Ampera Bridge, passenger access to LRT stations and Skate Park. The various functions of this street caused the reduction in street service levels at certain hours and become a congestion point in Palembang city. This study aims to obtain the results of the analysis of Tengkuruk Permai’s street performance in the scenario conditions of terminal relocation and on street parking. The data were collected directly by measuring and enumeration then micro-simulated with the Vissim software. Vissim microsimulation modeling is carried out in existing conditions and scenarios by combining the 3 (three) floors parking building construction plans, city transport routes, Tengkuruk Permai street which has been cleared of on street parking and terminals, street networks around the research location and intersection arrangements concurrently. The street performance analysis uses the calculation of the V/C ratio, where the calculation of the street capacity uses the Vissim microsimulation output such as speed, density and volume obtained in the link of segment evaluation menu. Capacity determination is using the calculation of relation of flow (q), velocity (v) and density (k). The scenario of relocating the city transport terminal and street parking to the 3 (three) floors parking building plan at 16 Ilir market parking lot can increase the capacity of Tengkuruk Permai Street from 1087,88 pcu/hour/direction to 2295.15 pcu/hour/direction and improve the service level from level E to level A.

Abstract

The construction of Musi V Bridge is part of the series of Kapal Betung Toll Road, with the toll road in and out of Social Street which is connected to Lettu Karim Kadir Street. This study aims to obtain the performance of roads and intersections in Gandus District, obtain transportation modeling of traffic movements due to KayuAgung-Palembang-Betung Toll Road interchange, obtain predictions of the performance of roads and intersections resulting from traffic simulation models and provide policy suggestions in the form of strategies and traffic engineering management techniques. Data processing used the 2014 PKJI method and simulation with Vissim program. Results of data processing show that the performance of roads and intersections in existing conditions is still able to accommodate traffic flow, indicated by the degree of saturation that meets 2014 PKJI requirements, namely (DJ ≤ 0.85) with service level C and Vissim simulation results show the largest delay and queue length located in segment 3 (M Amin Fauzi Street -Tph Sofyian Kenawas Street) which is 138.18 meters and 21.02 seconds and on Lettu Karim Kadir Street (Direction of Musi II) of 14.04 seconds and 58.96 meters. After the operation of the Musi V Bridge, there was an increase in traffic volume which resulted in decreased performance of roads and intersections. Therefore, to improve its performance, road widening is carried out. The results of 2014 PKJI analysis showed a decrease in the degree of saturation from 0.43 to 0.35, a delay from 9.02 seconds / cur to 8.22 seconds / cur and the chances of queuing from 8.50 - 20.39% to 6.04 - 15.91% on Lettu Karim Kadir Street (Musi II Direction).
