π Impact of Vehicle Speed on Road Safety
The speed of motor vehicles is one of the most critical factors contributing to road crashes, injuries, and fatalities. It affects both the risk of accidents and the severity of consequences.
β οΈ Excess & Inappropriate Speed
- Excess speed: Driving above the speed limit
- Inappropriate speed: Driving too fast for road or traffic conditions
π Modern Vehicles & Risk
Modern vehicles accelerate quickly, increasing crash riskβespecially at junctions and during overtaking. Drivers often underestimate speed and overestimate distance.
π Empirical Evidence
+3%
Increase in injury crashes per +1 km/h
+4β5%
Increase in fatal crashes per +1 km/h
π Impact on People
- Fatal injury risk rises from 0% to ~100% when speed increases from 20 km/h to 100 km/h
- Seatbelt users face 3β4Γ higher injury risk at 48β64 km/h vs 32 km/h
- Pedestrians have 90% survival at 30 km/h, but <50% at 45 km/h
- Pedestrian fatality risk increases 8Γ from 30 km/h to 50 km/h
βοΈ Effects of Speeding
- β±οΈ Reduced reaction time
- π Increased stopping distance
- π₯ Higher crash severity
- π οΈ Increased tyre & brake wear
- ποΈ Reduced visibility & judgment
