SEA-UEMA Supports Jakarta Car-Free Day
Posted by uemindonesia on May 27, 2009
SEA-UEMA Project has supported the Urban Regional Development Institute (URDI) of Jakarta, Indonesia to implement a pilot project to monitor and assess environmental impacts of a Car-Free Day (CFD) on ambient air quality in a particular corridor in Jakarta. CFD was first introduced in the US in the 1970s and has been used to promote and encourage alternative modes of transport on busy roads and streets limited to vehicle use. A car free day would help measure the reduction in air pollutants and noise reduction and help promote alternative non-motorized transport systems.
Three air quality parameters (particulates, carbon monoxide and nitrous oxide) from three ambient air monitoring stations on the Sudhirman-Thamrin Corridor in Jakarta’s central business district were measured. One of the CFDs implemented on August 31, 2008 from 6:00 to 14:00hrs indicated a substantial reduction in air emissions by comparing parameters measured on weekdays and holidays. The reductions of air emissions for the above three parameters have been observed to be more than 60% in most cases, without considering the change in meteorological pattern. Data from 10 CFDs have been used to study the effectiveness of each event.
It has been observed that during the CFD implemented by URDI, car free roads were well utilized by the public for nonmotorized transport such as bicycles while some people used the roads for leisure, social and sports activities. Thus the event not only promoted activities for the community in and around the corridor but also helped in socialization for those who live in high-rises and compact settlements.
The air quality measurements also indicated that more frequent CFDs would pave way towards improving air quality in the city while creating awareness among the people about the need for improving ambient air quality for better environmental health. Though conclusive results have yet to be derived through modeling, the initial inferences indicated improved ambient air quality. These positive results are expected to pave the formulation of effective policies promoting alternative means of transport to improve the air quality standards in Jakarta.
