A vehicle's overall stopping distance consists of thinking distance followed by braking distance. Match each factor to its specific and direct effect on these distance components.
- Driver cognitive distraction caused by a hands-free mobile phone callIncreases thinking distance by delaying hazard perception and driver reaction
- Increasing vehicle speed while maintaining the same physical reaction timeIncreases thinking distance because the vehicle covers more metres per second during reaction time
- Standing water and wet road conditions on the carriagewayIncreases braking distance due to reduced tyre grip on the road surface, leaving thinking distance unaffected
- Significantly worn brake pads and degraded brake fluidIncreases braking distance by reducing mechanical friction efficiency, having no effect on driver thinking distance
Cevap
Driver cognitive distraction matches with increasing thinking distance via delayed perception; Increasing vehicle speed matches with increasing thinking distance due to greater distance covered per second; Standing water matches with increasing braking distance due to reduced tyre grip; Worn brake components match with increasing braking distance due to reduced mechanical friction.
Total stopping distance consists of thinking distance plus braking distance. Thinking distance is strictly influenced by two parameters: the driver's reaction time (affected by fatigue, alcohol, drugs, illness, and distractions such as phone conversations) and vehicle speed (higher speed covers more distance in the same time). In contrast, road conditions (wet asphalt) and vehicle maintenance (worn brakes) only influence braking distance.
