GONZALEZ, Juan F  e  PRADA, Sergio I. Photo Detection Cameras and Road Accidents. Evidence for the City of Cali. Desarro. soc. [online]. 2016, n.77, pp.131-182. ISSN 0120-3584.  https://doi.org/10.13043/DYS.77.4.

This paper aims to evaluate the impact of photo detection cameras installed in the city of Cali (Colombia) in 2012 on road accidents. Using 10.146 intersections with accident records for the period 2010-2013, a matching algorithm is used to identify a control group. Using different estimators, an evaluation of total accidents, damages and injuries is carried for treated intersections, compared to the control group, after the cameras were installed. Findings show an increase in all types of accident records on the four intersections treated in January 2012, this effect is reduced for those intersections treated in May, and it disappears in those treated in August. The main conclusions are that accidents were not reduced by the camera program and that accident history was not the criterion for treatment assignment.
