This research investigated the problem of air pollution caused by vehicles in the city of Tripoli, Libya. This also included the identification of the socioeconomic and institutional factors which have contributed to the increased severity of the air pollution problem. The issues addressed included legal, institutional and technical aspects. A descriptive method was applied in which a case study approach was adopted. Primary data were collected through personal interviews with responsible people in relevant institutions, including EGA, GTL and ATD, complemented by questionnaires and direct observations. The data collected from the interviews and questionnaires were analysed using Excel and SPSS software. Owing to the lack of data on vehicular emissions in the study area, an inventory of the annual vehicular emissions in the city was made through the application of COPERT.4 software which is widely used for calculating vehicular emissions. This inventory covered the period from 2005 to 2010. Laboratory Mobile was also used to measure the concentration of vehicular emissions in the city centre of Tripoli, and compared with the vehicular concentrations in Sheffield, UK, for the same period. A framework was developed and validated to evaluate the air pollution caused by vehicles in Tripoli. The findings from the research showed that there has been a dramatic increase in the quantity of vehicle emissions in the city, highlighting the extent of the problem. Some influencing factors which have made a significant contribution to the occurrence and increased severity of traffic air pollution in Tripoli include: the increase in the vehicle fleet, the quality and quantity of the fuel consumed, insufficient public transportation, a shortage of public awareness, and deficiencies in the relevant legislation. Obstacles facing the responsible institutions include a lack of capable and qualified staff, and a shortage of necessary equipment for monitoring and addressing traffic problems and pollution. It is concluded that Tripoli has been subjected to air pollution caused by vehicles, which needs to be addressed through the incorporation of a comprehensive strategy and implementation of the developed framework. Additionally, economic, legal, institutional and technical recommendations are presented for the management of air pollution caused by vehicles in the city of Tripoli, Libya.
