Abstract

A macroscopic movement of traffic consists of traffic volume, speed and density which are used to evaluate the quality of transportation system. By analysing these three variables, a result which infrom about the condition about a transportation system will be provided. The information from the analysis of the variables shows the condition of the traffic condition through the traffic volume and density. When a road has a bad condition of transportation system, the analysis will describe it through high density of traffic and the maximum traffic volume is exceeded.This research is conducted on Padjajaran Street to evaluate the characteristic of transporatation system on the road.The data, which were collected, consists of traffic volume and spot-speed on every lane of the road. Those were collected on Monday, Wednesday, Saturday and Sunday at peak-hours, which are 6.30am-8.30am, 11am-1pm and 4pm-6pm. The analysis used vehicles classification according to MKJI 1997 and conducted an analysis through several models, which are Greenshield, Greenberg, Underwood and Bell models. By comparing these four models, the best one is chosen and become the model to describe the quality of the transportation system on Padjajaran Street.The best result according to the value of R2 and the analysis of the traffic variables, every lane has their own best model which can be applied. However, most of the lanes are well-modelled using Underwood method. Finally, it comes to a conclusion that Padjajaran Street is classified as urban road.

Abstract

In 2008, the city of Yogyakarta adopted a buy the service scheme in the Trans Jogja public transport aiming to improve the quality of public transport and reduce congestion. Based on the study of GIZ-SUTIP in 2012, there were several problems in Trans Jogja, including inadequate bus stops and excessive staff numbers. The aim of our study were to evaluate and improve bus stops performance and analyze bus stop service quality according to passenger perceptions. This study is a descriptive study using purposive sampling technique, conducted on 12 Trans Jogja bus stops and 180 respondents. The data obtained were analyzed using MS Excel and SPSS 22 computer program. The results showed that bus stop performance was not good on headways, waiting times, and on-time performance. The clearance time of far-side bus stops was shorten than near-side and mid block bus stops. The near-side and far-side bus stops were accessed by passengers on foot. The service quality of the Trans Jogja shelter does not match the expectations of the passengers with a Gap Servqual value of -0.790. The service attribute was in quadrant C of the Cartesian Diagram, that requires corrective action from the Trans Jogja operator.

Abstract

An evaluation of the condition and performance of the BBT Port needs to be carried out because of the significant increase in the number of tourist visits to the Bintan Beach International Resort area. Still, since its inauguration in 1994, the port has not changed much. Passenger terminal needs are commonly defined through projections using the exponential trend method based on ship and visitor flows in the last five years. A port performance is based on BOR (Berth Occupancy Ratio) calculation. In contrast, for the performance evaluation of passenger terminal services is based on the perception of tourists as passenger terminal users obtained from the questionnaire results with a Likert scale and the Importance Performance Analysis (IPA) method from the IPA, interviews with the BBT port manager, are conducted by using the Strength Weakness Opportunities Threats (SWOT) method to formulate the development strategy. The analysis result shows that it needs to increase the waiting area up to 613 m² in 2033, and the parking area of 17,173 m², while the BOR at the BBT port is still in a proper category, by  24.11% of the UNCTAD 50% requirement. In evaluating the passenger satisfaction to the port services, the improvement focuses on the priority quadrant, namely the physical condition of the BBT port facilities. Next, formulating a development strategy in terms of physical aspects and management to adjust the passenger needs, and the BBT port is ready to face business competition in the future.

Abstract

Karet Station has an average number of passengers at 12,594 people per day in 2018, has a large potential of pedestrian trip generation. The basic problem experienced by pedestrians at Karet Station is when they (KRL passengers) leave the station, they cannot find a clear pedestrian path to accommodate their movement towards other public transport facilities. As the result, the pedestrians scattered and even crossed the road and stopped the public transportation arbitrarily. This activity causes a high risk of accidents and traffic flow constraints caused by reduced capacity of road section due to public transport activities while waiting, lowering, and raising passengers. The purpose of this research was to analyze the pedestrian lane characteristics, and service level based on technical guidelines and stated preferences of passangers. In this research, the primary data were collected by conducting direct surveys in study area to get characteristics of pedestrian, traffic flow, and passanger perception about pedestrian facilities performance. Analytical results from this study conclude that from technical guidelines approach, there are two sidewalk segments in the Karet Station area which require special attention with the level of service categori at C and E level, and  also requires improved pedestrian crossing facilities from zebra cross type to be underpass or pedestrian bridge. Based on stated preferences approach, from the assessment of 24 service attributes, there are 6 attributes of lowest performance services included in quadrant I of Importance Performance Analysis (IPA) matrix which are the main priority that must be resolved immediately.
