title: Road Safety Effects of Bus Rapid Transit (BRT) Systems: a Call for Evidence.
abstract: Road injuries are an important cause of global mortality especially in low- and middle-income countries. While these countries undergo major urban transformations, an integral part of their development has often been the implementation of mass transportation systems, including Bus Rapid Transit (BRT) systems. However, the net effect of BRT systems on road safety is still unclear, and while there is reason to believe that BRT systems improve safety, very few available empirical studies have tested this hypothesis using observational data. Furthermore, the existing evidence is mixed and sparse. This paper reviews the available literature on the links of BRT systems and road safety and calls for more research to strengthen the body of evidence on the effect of BRT systems on road safety  in the future.
