Evaluation of Public Transportation Projects with Equity Considerations: Preliminary Findings from Mamminasata, Indonesia
ABE Ryosuke, YATMAR Hajriyanti
Journal of the Eastern Asia Society for Transportation Studies 16 ( 0 ) n/a 2025 [Reviewed]
Language：English Publishing type：Research paper (scientific journal) Publisher：Eastern Asia Society for Transportation Studies Joint Work
<p>This study examines the impact of public transportation projects by considering the bus service areas and equity considerations for various groups in Mamminasata. Data were collected through interviews in bus corridors to understand activities, travel behavior, modes, and attitudes toward travel and residence. This study analyzed data from 837 residents and a seven-day diary using descriptive statistics. The demand for the bus with an incremental interval radius, ranging from bus stop at 1 km, 1.5 km, 2 km, is 0.12%, 0.47%, and 0.24%, respectively. However, even though the bus fare is uniform across income groups, the low-income group highest costs (IDR 1,157) or 19.09 percent higher when using bus, and 79.96% higher for ride hailing for one trip compared to private modes. The total number of trips in one week indicates that after private, ride hailing is used more for work trips, whereas buses are used more for leisure trips.</p>

RESEARCH ON THE ACTUAL SITUATION OF CROSSING BY BUS PASSENGERS
NAKAJIMA Satoshi, TANAKA Shinji, MATSUYUKI Mihoko, ABE Ryosuke
Japanese Journal of JSCE 80 ( 8 ) n/a 2024 [Reviewed]
Language：Japanese Publishing type：Research paper (scientific journal) Publisher：Japan Society of Civil Engineers Joint Work
<p> In 2018, a traffic accident occurred at a bus stop in Yokohama City. A 10-year-old girl who got off the bus and crossed behind the bus was struck by an oncoming vehicle. In response to it, bus stops have been relocated or removed to improve safety at bus stops in Japan. However, there has been no widespread use of cautionary measures at bus stops targeting regular drivers. In addition, previous studies and surveys have focused on crossings outside of crosswalks at bus stops, not crossings from the shadows of buses and crossings while attempting to get on a bus. This study aims to clarify the actual situation of crossings by bus passengers, focusing on crossings from the shadows of buses and on crossings while attempting to get on buses. Observations from inside buses suggested that the rate of crossing at 10 m in front of and behind buses was high at the bus stops in front of stations. Multiple linear regression analysis revealed that the rate of crossing at 10 m in front of and behind buses is higher when the speed limit is 30 km/h, when the traffic signal is far away, and when there is a non-signalized intersection on the opposite side of the road. Based on the results of this analysis, we suggested that road markings should be provided at bus stops with non-signalized intersections because they reduce the danger of both crossings from the shadow of buses and crossings from the shadow of non-signalized intersections.</p>
