Park and Ride (P&R) systems play a potentially important role in transportation planning
to decrease the undesirable effects of private cars in the Central Business District
(CBD). In order to achieve this objective, an essential component to be investigated
is the catchment areas of these P&R facilities. However, a limited number of studies
have applied the Geographic Information System (GIS) to study the spatial boundary
accessibility of the catchment areas of P&R. This study aims to analyze the spatial
boundary accessibility of the catchment areas of P&R facilities using three GIS methods.
The first method uses geometric shapes to analyze the catchment areas of P&R facilities
according to regular shapes, such as parabolas or circles. The market area is the
second method used to analyze travel time via the tool ArcGIS Network Analyst to determine
the catchment area of P&Rs. Finally, the dynamic accessibility method determines how
accessible a facility can be through a study of the spatial boundary accessibility
of P&Rs based on the travel time and distance between zones and P&R. The result shows
that the static methods identify the spatial boundary accessibility through the calculation
of the size of the shape of each P&R separately, while the dynamic method identifies
the level of accessibility in detail for all P&R and also the accessibility of each
zone to reach a facility. In conclusion, the dynamic accessibility method presents
better accuracy than static methods in order to estimate the spatial boundary accessibility
of the catchment area of P&Rs.
