Abstract

Limitation of parking spaces in Petra Christian University need to be solved by deterring private cars usage. However, the factors that affect students to choose their mode to campus are unknown. Determination of factors that influence mode choices may support alternatives and policy that could be proposed. Analytic Hierarchy Process was used to analyze the factors. Trips characteristics data of the students was collected by questionnaires interview. The results of the analysis show that the main factors that influence student to choose their mode to campus is security (49,3%) and time (27,3%). Walking from student dormitory was the best alternative (33.2%), while carpool (16%) is slightly lower than private cars usage (18%). Vanpool (12.4%) is lower than carpool. Abstract in Bahasa Indonesia : Lahan parkir di Universitas Kristen Petra yang terbatas, memerlukan solusi alternatif yang mengalihkan penggunaan kendaraan pribadi. Permasalahannya, faktor-faktor apa yang menyebabkan mahasiswa memilih menggunakan mobil pribadi daripada alternatif moda yang lain belum diketahui. Dengan menentukan faktor-faktor yang mempengaruhi pemilihan moda, serta besar pengaruhnya, berbagai alternatif dan kebijakan untuk menurunkan kebutuhan akan lahan parkir, dapat diusulkan dengan lebih efektif. Metoda Analytic Hierarchy Process (AHP) dapat dipergunakan untuk menentukan faktor-faktor pemilihan moda. Data karakteristik perjalanan dilakukan dengan wawancara berkuisioner kepada mahasiswa Universitas Kristen Petra yang mempunyai kemungkinan untuk melakukan pilihan terhadap alternatif-alternatif moda yang ada. Hasil analisa menunjukkan bahwa faktor utama yang mempengaruhi pemilihan moda untuk berangkat kuliah adalah faktor keamanan (49,3%) dan faktor waktu (27,3%). Ditinjau dari berbagai faktor, alternatif jalan kaki dari pondokan merupakan alternatif yang terbaik (33,2%), sedangkan carpool (16%), sedikit lebih rendah daripada penggunaan mobil pribadi (18%). Angkutan kampus (antar jemput) justru lebih rendah daripada carpool (12.4%). Kata kunci : Analytic Hierarchy Process, parkir, faktor pemilihan moda.

Abstract

Several interesting properties of a special type of matrix that has a row sum equal to the column sum are shown with the proofs. Premagic matrix can be applied to strongly connected directed network graph due to its nodes conservation flow. Relationships between Markov Chain, ideal flow and random walk on directed graph are also discussed.

Abstract

The need of tools for design and evaluation of pedestrian areas, subways stations, entrance hall, shopping mall, escape routes, stadium etc lead to the necessity of a pedestrian model. One approach pedestrian model is Microscopic Pedestrian Simulation Model. To be able to develop and calibrate a microscopic pedestrian simulation model, a number of variables need to be considered. As the first step of model development, some data was collected using video and the coordinate of the head path through image processing were also taken. Several numbers of variables can be gathered to describe the behavior of pedestrian from a different point of view. This paper describes how to obtain variables from video taking and simple image processing that can represent the movement of pedestrians and its variables

Abstract

The current trend of queuing theory development is toward more precision which requires higher mathematical manipulation. In this paper, we attempted to reverve the current trend toward simplification of queuing formulas such that it can be used in more practical purposes, especially in construction industry. Through numerical examples of two case studies on concreting and earth moving, how to model the construction activities as queuing systems is illustrated systematically. Through the numerical examples, it is shown that when the customer cost is much lower than the server cost, queuing system can be simplified only to incorporate the constraint equation. The queueing constraint equation is suggested to be used as queuing rule of thumb. The proposed rule of thumb is rather conservative in term of queuing performance compared to the standard stochastic queuing formula because it is assumed that all the customers arrive at once in the beginning of the service.

Abstract

A proposed road project inside a campus that will have to down trees from its mini forest have attracted different public opinion among the faculty and students. In this paper, we would like to justify our view objectively based on transportation engineering point of view. The Ideal Flow Network (IFN) method was used to do the analysis because its source code is publicly available for clarification. The network data is based on previous study of Ateneo Traffic Group report. Two scenarios were set: based scenario that represents the current road network, and two proposed scenario that represents the current road network with additional proposed road in two ways and one way respectively. Analysis of the results show that the total network travel time of the proposed scenario are increased by 4.69% and 2.32% respectively for two ways and one-way scenarios. The network speed will be slightly improved by 0.03% in when the proposed road project is added in two ways. Thus, we failed to justify that the proposed network has better network performance.
