- Abstract
Traffic calming measures combat speeding and other unsafe behavior by drivers, proving effectiveness in reducing the frequency and severity of accidents. However, some measures include road bumpers that cause negative impact on the environment. This work analyzes the repercussion of reducing the vehicle speed on contaminating emissions and fuel consumption (FC) when driving over a bump. To do this, this paper presents a procedure based on two methods applied to RDVs. The first, based on an application, measures the physical impact on a vehicle from acceleration taken with the IMU of a smartphone in a direction perpendicular to the chassis. The second infers the increase in emissions and FC by taking the speed-time profile of a road. The experimentation with a standard two-passenger vehicle circulating on a road with RDV of trapezoidal and circular sections vs without RDV found a significant physical impact in both scenarios, increasing the emissions of CO, HC, NOX, CO2 and FC by decreasing 10 and 20 km/h. This demonstrates the generalization and usefulness of the method to study the increase in emissions and FC of «traffic calming» measures.
