| August to November 1998 | | Case study: Dakar | | In Dakar, most motorized trips (86 percent) are made on medium-to-high capacity buses, called cars rapides, owned by the private sector. About 70 percent of vehicles are more than 10 years old, with emission levels about twice as high as those less than 10 years old; diesel fuel is used by 90 percent of buses and 33 percent of personal vehicles. It was determined that vehicle age (rather than vehicle type) and fuel related measures must be the focus of action to reduce pollution. |
Objetives of the study: To define the main causes of transport dysfunction, quantify them, express them in figures, and recommend a suitable framework for monitoring changes in the parame-ters. The area studied is the Dakar agglomeration, which has more than 2.2 million inhabitants, 1.2 million of whom live to the east of the city itself, in the Pikine-Guédiawaye Rufisque area.
