MICRO SIMULATION OF PELICAN CROSSING AT THE ROAD SECTION OF COLOMBO STREET, YOGYAKARTA
Abstract: Yogyakarta has a
problem related to pedestrians. The inappropriate implementation of crossing
facility and disobedience of pedestrians while crossing the street leads to
conflicts between pedestrians and vehicular traffic. Taking the road section of
Colombo Street as the case study, this research proposed pelican crossing with
independent and coordination time signal operation. Using Aimsun software, the
existing traffic signal, geometric design, traffic flow and turning proportion
were taken into account to build the initial model. Afterwards, a calibration
of queue length and a validation of vehicle speed were carried out to obtain a
basic model which represents the existing condition of the system. Comparing
the basic model and the alternatives in terms of performances of junctions,
road section and pedestrians in the pelican, this research resulted in setting
double cycling of pelican as 100 seconds for the independent operation and
setting common cycle time 120 seconds for the coordination operation as the
best alternatives. In addition, the implementation of pelican crossing brought
about the reduction of vehicle speed in the road section so that the safety of
pedestrian increased.
