Abstract

Salah satu kendala dalam perhitungan kinerja simpang bersinyal baik secara manual maupun dengan mempergunakan software Kapasitas Jalan Indonesia (KAJI) adalah untuk memperoleh nilai optimum dari berbagai nilai parameter seperti waktu hijau, lebar lajur belok kiri (WLTOR), lebar satu lajur lurus dan atau belok kanan, dan jumlah lajur setiap lengan pendekat terhadap nilai derajat kejenuhan (DS) tertentu, diperlukan perhitungan secara berulang secara manual yang membutuhkan waktu lama. Tujuan dari pembuatan aplikasi ini adalah membuat aplikasi spreadsheet dengan mempergunakan fasilitas Add-in Solver pada Microsoft Excel, untuk mempermudah memperoleh waktu hijau, WLTOR, lebar satu lajur lurus dan atau belok kanan, dan jumlah lajur setiap lengan pendekat yang memenuhi batas nilai DS tertentu berdasarkan Manual Kapasitas Jalan Indonesia (MKJI) 1997. Setelah dilakukan perbandingan antara perhitungan KAJI dengan perhitungan aplikasi spreadsheet, terdapat perbedaan pada nilai DS dan nilai tundaan total karena adanya perbedaan asumsi dalam perhitungan nilai faktor penyesuaian parkir (FP).

Abstract

Penelitian ini dilakukan untuk mengetahui alternatif manajemen lalu lintas yang dapat mengurangi kemacetan pada persimpangan antara Jalan Raya Jemursari dengan Jalan Margorejo Indah sehingga kinerja jaringan jalan di sekitarnya meningkat. Data hasil survei asal-tujuan diolah menjadi model sebaran pergerakan, kemudian model pemilihan rutenya dibuat dengan bantuan software perencanaan transportasi dan dibebankan pada idealisasi jaringan jalan. Setelah itu, dilakukan analisis untuk menemukan alternatif manajemen lalu lintas yang menghasilkan kinerja jaringan jalan lebih baik daripada kondisi aktual. Dari sekian alternatif yang dianalisis, terdapat empat alternatif yang memberikan hasil positif terhadap peningkatan kinerja jaringan jalan secara umum. Bahkan ada alternatif yang mampu mengurangi nilai derajat kejenuhan lalu lintas hingga 17%. Pada akhirnya dipilih dua alternatif yang menghasilkan kinerja terbaik dan stabil selama jangka waktu perencanaan. Salah satu dari dua alternatif tersebut yaitu usulan membuat jembatan layang dua tingkat untuk kendaraan yang ingin menyeberang dari Jalan Raya Jemursari menuju Jalan Margorejo Indah dan sebaliknya. Sedangkan alternatif lainnya yaitu usulan membuat pelebaran jalan di beberapa ruas Jalan Raya Jemursari untuk mengakomodasi kendaraan yang melakukan putar balik kanan langsung pada persimpangan.

Abstract

Sepeda motor menjadi salah satu pilihan moda transportasi yang populer di kalangan mahasiswa yang membawa dampak positif maupun negatif terhadap kampus dan lingkungan sekitarnya. Penelitian ini bertujuan untuk mengetahui faktor-faktor yang mempengaruhi perilaku mahasiswa pengendara sepeda motor ke kampus berdasarkan Teori Perilaku Terencana (Theory of Planned Behaviour, TPB). Data primer diperoleh dengan melakukan survei pada lima universitas yang ada di Surabaya. Sebanyak 414 responden memberikan respons terhadap pertanyaan berkaitan dengan perilaku perjalanan mereka ke kampus. Data yang diperoleh kemudian dianalisa dengan teknik Structural Equation Modeling. Hasil penelitian mengindikasikan bahwa faktor persepsi kendali perilaku secara positif dan signifikan mempengaruhi intensi perilaku mahasiswa pengendara sepeda motor ke kampus. Faktor sikap dan norma subjektif tidak memberikan pengaruh yang signifikan terhadap intensi perilaku. Demikian halnya intensi perilaku terhadap perilaku aktual. Implikasi penelitian ini dapat menjadi masukan bagi pihak kampus dapat menerapkan Manajemen Transportasi Kampus yang sesuai untuk mengurangi penggunaan sepeda motor ke kampus.

Abstract

The use of car by students as a primary mode for commuting to campus has profound effects on campusparking requirements and traffic congestion at peak hours. It is interesting how to reduce the amount ofparking provided and also minimize traffic congestion, but still meet transportation demand. One of thealternative solutions was Campus Transportation Management (CTM), with the purpose of improvingtransportation efficiency by reducing car dependency by changes to other transport modes. Carpool is one ofthe most common and cost effective alternative modes, particularly in areas that are not well served by publictransit. This paper aims to recognize the respond of the students regarding the carpool program and to mappotential zones and routes for the implementation of carpool at Petra Christian University. The result show, ifthe carpool program is be implemented at Petra Christian University, it should begin with several routes themost participants and meet the carpool conditions (participant schedule and characteristics).Keywords: campus transport management, carpool route, carpool matching.

Abstract

The most common daily trip for students is the commute to and from campus. Students tend to choose car when commuting. This preference has resulted in a number of negative effects. Therefore it is necessary to investigate the psychological factors influencing students’ car use behavior. The popular theory of plannedbehavior (TPB) was successfully applied by different authors to explain people’s travel mode choices.According to TPB, intentions are the closest antecedents of behavior, and intentions were resulted fromattitudes, subjective norms, and perceived behavioral control. TPB assumes that these components are in turndetermined by salient beliefs for each component and evaluations of those beliefs.This study elicit students’salient beliefs in relation to car commuting, that could be used to construct a full TPB questionnaire. Thisquestionnaire could then be used to investigate student car commuting behavioural intention. A sample ofstudents from four different university, with a sample size of 200 people, completed questionnaires with eightopen-ended questions eliciting beliefs concerning car use. The results indicated that the most frequentlymentioned salient beliefs related to behavioral beliefs are comfort, security, flexibility, prestige, parkingfacilities, congestion, and travel cost. Meanwhile, those related to normative beliefs are parents,boyfriend/girlfriend, and friend, and those related to control beliefs are parents, car availability, number ofcar owned, car’s technical problem, congestion, and travel cost.Keywords: theory of planned behavior, student’s salient beliefs, car use for commuting.

Abstract

The most common daily trip for students is the commute to and from campus. Though there are clear environmental, economic, and social drawback from using private vehicles for these trips, students still choose private vehicles to get to campus. This study reports an investigation of psychological factors influencing students’ behavior to commute by car from the perspective of the Theory of Planned Behavior (TPB). Students from three different university campuses (sample size of 312) completed a survey on their car commuting behavior. Results indicated that all relations postulated by the TPB are confirmed and perceived behavioral control was the strongest factor that influences students’ intention. Attitude, subjective norm, and perceived behavioral control explain 59% variance of the intention while intention explains 58% of the variance of the actual car use. Implications of these findings are that in order to alter the use of car, interventions should target the perceived behavioral control of commuting by car.

Abstract

The increasing use of cars by students impact on traffic congestion and the increasing need for parking spaces. This study has several objectives , namely (1) determine differences in travel expenses for students who use cars and vanpool services, (2) determine barriers for students who have not and who never use the vanpool service, (3) find out the facilities and vanpool fares desired by the student, (4) determine the value of the Benefit Cost Ratio shuttle service operators at present, and (5) estimate a deficit or surplus experienced by the campus, as a result of tariff subsidies for shuttle services and finance the shuttle service management. The results of this study indicate that the cost of travel by using a shuttle service is cheaper than using a car for traveling to campus if the distance from residences to campus greater than 9 km, and the subsidies granted for vanpool fares and vanpool office cost, can help overcome constraints associated with the shuttle service, parking demand reduction, and provide a budget surplus to fund other campus transportation management strategies.Keywords: parking demand, campus transport management, vanpool

Abstract

Congestion that occurred in the vicinity of Petra Christian University campus tends to increasing on the peak hours. One of the possible solutions to reduce congestion is to revamp the geometric design of campus access, as proposed in the final report of PCU Master Plan. The study was conducted to determine differences in the intersection performance indicator between the existing conditions compared with the proposed access design. The data was collected through survey of road inventory, origin-destination, and turning movement. The traffic assignment process carried using Trafikplan software, and analysis of the access performed by using software KAJI. Based on the result, it can be inferred if the proposed design ofgeometric access implemented, the intersection capacity estimated to be increase up to 46.6%, degree of saturation reduce up to 31.9%, intersection delay reduce up to 57%, and queue probability reduce up to 50.9%; compared with the existing access conditions till the year 2020. The demand management program should also be considered as an option to reduce congestion.Keywords: unsignalised intersection, reversible lane
