Summary: | Pedestrians are frequently perceived as one
of the sources of traffic congestion due to their illegal occupancy of the
roadway. The goal of this study is to examine this issue by investigating the
feasibility of pedestrian facilities and the effectiveness of utilizing a
pedestrian bridge at a certain congested area: the north-bound traffic in Jalan
Lenteng Agung, Jakarta. The feasibility of a facility is represented by an
indicator of the Level of Service (LOS), i.e. the space occupied by one
pedestrian, and is supported by an assessment from the pedestrian’s point of
view, using a questionnaire covering various aspects of the issue. The
assessment of its geometric feasibility is also carried out, using the design
specifications issued by the Directorate General of Bina Marga (1990) to
strengthen the analysis. Meanwhile, the effectiveness of using a pedestrian
bridge is represented by the ratio of pedestrian bridge users to the total
number of people crossing the street. Data collection related to pedestrian
flow is carried out using web cameras. The analysis shows that the LOS of all
the segments of the pedestrian facilities ranges from LOS A to LOS C, in which
LOS C represents the pedestrian bridge. LOS measures, supported by the
geometric feasibility assessment results, signify that the facilities are not
yet feasible; the speed of pedestrian flow needs to be increased using
geometric improvement and the elimination of all disturbances throughout the
facilities. Meanwhile, the effectiveness of using the pedestrian bridge is only
50.26% (meaning it is “quite useful”); the remaining percentage of pedestrians
cross the road by navigating through the road traffic. The questionnaire results
show that people are indeed aware of the importance of the safety issues
related to bridge usage; however, they are reluctant to use it due to the
physical barriers. The improvement generated from the analysis may help
increase bridge use and its LOS, and eventually reduce the disturbance of
vehicle flow. |
