In the Philippines, we have many low-capacity motorized transport modes in service, ranging from three-wheeled tricycles (or tricycabs) to 20-seater dyipnis or jeepneys (or jeep); from UV Express ("Utility Vehicle" - a franchise public transport owned by the Land Transportation Franchising and Regulatory Board, a national agency) to habal-habal (motorcycles) and of course, the usual taxicabs. Aside from the evident increasing number of private vehicles in most Philippine cities, more and more people still rely on these low-density motorized vehicles, thus the demand for these transport mode is, likewise, on increase. Since high-capacity transport modes are only available on major thoroughfares, the abundance of these low-capacity vehicles is evident literally everywhere, further worsening the already congested road networks. Additionally, most of these transport modes do not have legitimate transport stops, making the roadsides/ sidewalks as their stops most of the time which is very unsafe/ unhealthy not only to passengers, but to pedestrians as well.
One specific problem of these transport modes is the absence of organization/ timetable of their trips, particularly the jeepneys. Mostly during rush hours, it would be easy to assume we need more jeepneys to accommodate the huge number of people on queues (on sidewalks and/or roads) to be serviced, however, after rush hours, there are still a lot of them plying the road with relatively very few passengers, thus, likewise, it would be easy to assume we have lots of these jeepneys carrying few/no people. The carbon emission/production is relatively constant throughout the day, even on non-peak hours. Local transport regulation agencies should really consider the establishment of a specific timetable/ schedule and the number of jeepneys plying the road at a specific time-frame, to properly accommodate the huge number people and to minimize the carbon emissions brought by these vehicles.
