Abstract
Enhanced public transportation coverage and reduced travel times not only improve convenience for commuters but also contribute to a more efficient and sustainable transportation system. Both factors enable more people to use public transportation and reduce the reliance on personal vehicles, congestion and emissions. This paper aims to analyze the impact of new public transportation lines on network coverage and travel time reductions in different zones of the Greater Cairo Region (GCR), using Open Trip Planner and GTFS. The study compares the existing public transportation system, mainly relying on informal means such as "micro-busses" and limited metro lines, with the enhanced public transportation currently under development. The analysis is conducted on a grid of 1,200 origin points covering the whole city with 8 destination points resembling main zones of GCR. As a result of the analysis comparing the travel times and availability of public transportation lines serving these points considering both scenarios of the existing as well as more comprehensive system with new public transportation lines, large number of points exhibit reduced travel times, indicating that the new routes have effectively enhanced the connectivity to these areas. The travel time reduction ranged from 6 to 24 minutes, 5 to 21%, implies that commuters could experience significant time savings on their daily trips. The analysis also identifies points that remain inaccessible even with the introduction of new public transportation lines. Across all zones, there is a substantial number of points (ranging from 214 to 257) that are not accessible through either the old or new transportation system.
