The Jabodetabek Transportation Master Plan (RITJ), stated in the Presidential Regulation Number 55 Year 2018 has been formulated based on nine pillars (traffic safety, environmentally friendly transportation, network infrastructure, road transportation, orbital transportation, traffic management, integrated transportation system, financial system, land use Integration). Not only BRT (TransJabodetabek) and LRT, TOD is also included in RITJ. Concrete plans are expected to be included in RITJ. In addition, improvement of access road to the public transport facilities in rural areas is also required by RITJ. Plans included in RITJ needs to follow direction of KPI (Key Performance Indicator) (will be discussed in more detail later) and it is necessary to emphasize countermeasures for traffic safety as listed in the above 9 pillars. Jabodetabek Transport Master Plan (RITJ), will be reviewed. Then, additional study items will be organized taking into consideration the changing socioeconomic situation and the current status of planned transportation infrastructure development projects, and necessary survey and analysis will be conducted. Since LRT is most likely to be the additional transportation infrastructure in the updated RITJ, in order to forecast the demand including evaluation of its impact, it is considered to be minimally necessary to subdivide the transportation analysis zones (TAZs) with socio-economic indicators along the planned LRT route. Moreover, the following Screen Line Survey, Classified Vehicle Counting Survey, and Cordon Line Survey are implemented. Among others, Cordon Line Survey has not been conducted since SITRAMP in 2002; hence, significant changes in the passenger and freight trips crossing the Jabodetabek boundary can be assumed. For comparative analysis, survey locations and items should be the same as those in the previous study.
1. Screen line Survey and Classified Vehicle Counting SurveysSurvey Objective: The main objective of the survey is to verify the present OD matrices which are estimated based on the results of the Activity Diary Survey. Also, by observing the traffic volume at some of the previous survey locations in Jabodetabek, the annual growth rate can be understood. Survey Location: The survey carried out at 91 locations (55 locations within Jakarta (16-hour survey) and 36 locations in Bodetabek area). The survey method of classified vehicle count is very simple. Number of vehicles that pass through the survey location shall be counted by type of vehicle and direction. The counting will be conducted by period of time; every 15-minute period over survey duration. For the counting and validation purpose, the traffic recorded using CCTV camera or other video recording devices and placed in a high place. CCTV data from private CCTV operator and/or Transportation Agencies also obtained.
2. Cordon Line SurveySurvey Objective: To obtain the number of trips flowing into and out of the Survey area at the cordon line survey stations in order to supplement the results of the Person Trip Survey. Survey Type: The modes of transport to be studied by the Cordon Line Survey and the contents are listed below:
3. Survey on Transfer Bottlenecks between Public Transport Lines (Passenger Transfer Bottleneck Survey). Survey Objective: To obtain data on how long it takes for passengers to transfer from a conventional bus, BRT, or railway line to another conventional bus, BRT, or railway line. Survey Outline: There are total 30 public transport transfer locations including conventional bus, BRT, and railway lines. At each transfer location, about 50 transferring passengers will be interviewed and asked about the bottleneck conditions including walk time and waiting time in the peak and off-peak time periods.
4. Activity Travel Diary Survey - Paper Based
The survey especially focuses on respondents who live in newly developed area since JUTPI 1 commuter survey in 2001. The survey implemented in Jabodetabek area (162 Kecamatan) with total respondents of 5.000 person from 5.000 households, conducted by conventional home visit interview and interview survey based on paper survey form, collecting socio-economic data (household, individual) and commuting trip data.
5. Activity Travel Diary Survey - Smartphone Based
The survey implemented using MEILI, an open source smartphone-based application for recording people’s trip or movement (mobility collector) developed and used in several area in European countries to obtain information about respondent’s trip pattern. JUTPI 2 develop the application by adding activity detail feature and adjusting the application with the condition of transportation system in Jabodetabek. The Activity Travel Diary Survey using Smartphone Application or ADS-MEILI is the first survey in Indonesia which recording respondent’s trip and activity by using smartphone application. The application recorded respondent’s trip and activity during 7 consecutive days, with the series of survey which consists of socio-economic survey and activity record survey targeting 5.000 respondents utilizing JUTPI 1 commuter trip survey respondent data.
A new regulation of controlling the traffic by allowing vehicles holding license plates of only odd or even numbers has been introduced to central Jakarta since 2016. In order to consider its impact, changes in the traffic volumes in the Screen Line Survey can be compared; furthermore, it is also possible to clarify the travel behavior by odd and even days (change in the choice of travel modes). Moreover, in the Travel Speed Survey in section below, it is also possible to analyze the impact of traffic congestion in the area surrounding the targeted roads. Other than above mentioned survey, in order to study the KPIs set by previous JUTPI 1 study and RITJ, the following two transport surveys on current conditions are implemented.
6. Travel Speed Survey
Survey Objective: To study the travel speed in order to understand the degree of traffic congestion and travel times, and to identify the congestion points by different time period and by day and also to calibrate/validate the transportation model. The data result will be utilized for updating RITJ and for proposing transport policies. Survey Outline: JUTPI 2 purchased 350 million GPS point data from the GPS provider company in September and October 2017 and developed GIS road network of roughly 5.000 links in Jabodetabek. The position data from the GPS provider will be gathered at a server on a real-time basis in order to obtain the average travel speed by section for all streets in Jabodetabek.
7. Truck OD Interview Survey at Major Freight Facilities
Survey Objective: To gain an understanding of the trip pattern of freight vehicles at their main departure and destination points, such as industrial areas and ports. The survey results will be used for transportation facility planning for large freight vehicles and as well as basic data for proposing heavy vehicle traffic regulations. Survey Outline: Truck driver interview and traffic counting, implemented in 11 locations (Kawasan Industri Pasar Baru, JIEP Pulo Gadung, KBN Marunda, MM2100, EJIP, Jababeka, Kawasan Industri & Pergudangan Cikupamas, Taman Tekno BSD, Greenland International Industrial City, Soekarno-Hatta Airport Cargo Terminal, Tanjung Priok Port). CCTV traffic count for validation conducted in 3 locations (Jl. Perintis Kemerdekaan, Jl. Bekasi Timur, Jl. DI Panjaitan).
Utilization of Transport Demand Software and Traffic Simulation Software
For independent and sustainable updating of the master plan, capacity building of the implementation agencies in the Indonesian side will be conducted through the activities explained above. Upon necessity, commercial transportation demand software and traffic simulation software applications that enable self-management of the tasks should be fully utilized. In JUTPI Phase 1, CUBE by Citilabs was the platform for developing the demand forecast models and PU Bina Marga is still utilizing CUBE; whereas, JUTPI 2 has purchased a transportation demand software application (VISUM) and a traffic simulation software application (VISSIM) by PTV and utilized them. Based on the updated transport database, travel demand forecast models will also be updated. Then, prioritization of the individual projects in the master plan details including new projects will be studied along with formulation of implementation plans (including implementation schedule and issues to be solved) in order to support CMEA, BPTJ, and relevant ministries and agencies as well as local governments. For detailing the master plan, scale of the demand, current progress, cost-benefit performance, financial feasibility, etc. should also be considered.
