Roadway noise is the collective sound energy emanating from motor vehicles. It consists chiefly of road surface, tire, engine/transmission, aerodynamic, and braking elements. Noise of rolling tires driving on pavement is found to be the biggest contributor of highway noise and increases with higher vehicle speeds. [1] [2] [3]
Single-vehicle crashes are classified into two groups: run-off-road (ROR), and on-road (OR) crashes in which the vehicle remains on the road after the crash. ROR crashes can account for up to 70% of the fatal single-vehicle crashes. ROR crashes are due to inattention, speeding, traction loss, overreaction, crash avoidance, and mechanical ...
The pre-collision braking control was upgraded in 2010 to allow the vehicle to stop automatically if the speed difference between the EyeSight-equipped vehicle and the object in front is less than 30 km/h (19 mph) and the driver takes no action to slow down or stop. Above 30 km/h (19 mph), the vehicle will reduce its speed automatically. [47]
Bernard was able to slow the car down to 50–60 mph (80–97 km/h) with the brakes, but was only able to bring the car to a complete stop after putting the car in neutral. [ 50 ] After this incident, Toyota conducted seven recalls related to unintended acceleration from September 2009 to March 2010.
A run-off-road collision with a tree in Kreis Pinneberg, Germany in 2010. A roadway departure [1] [2] (also called roadway excursion or run-off-road collision) is a type of incident that occurs when a vehicle leaves the roadway. Such incidents can lead to a single-vehicle collision.
A 2009 study conducted by the U.S. National Highway Traffic Safety Administration found that crashes involving pedestrians and bicyclists have higher incidence rates for hybrid electric vehicles than internal combustion engine (ICE) vehicles in low-speed vehicle manoeuvres such as reversing or leaving a parking zone. These accidents commonly ...

Traffic engineers refer to three "E's" when discussing traffic calming: engineering, (community) education, and (police) enforcement.Because neighborhood traffic management studies have shown that residents often contribute to the perceived speeding problem within their neighborhoods, instructions on traffic calming (for example in Hass-Klau et al., 1992 [4]) stress that the most effective ...
