They think it is safe to engage in distracted driving, for instance eating while driving, texting, using a phone to make a call, or manipulating the GPS systems or the radio.
The objective is to provide predictions about the position of the agent at the future steps. America`s rural transportation system is in need to make an improvements so it can support the economic growth and safety overall. Be careful if there is a bad weather condition.
The sliding window step for each valid full trajectory capture has been set to 1, in order to analyze all possible trajectories in each split. 46 kph respectively, compared to the straight segments (Table 4). Rural roads have often steep slopes. Oviedo-Trespalacios, O.

They have been applied for modeling traffic participant interactions [6]. There are different sources of distraction, from the vehicle itself 1 to the driving environment 1, 2.
The ABS modulator is the hydraulic assembly in vehicles that use the anti-lock braking system (ABS) to optimize the brake pressure. The braking system serves a vital role in slowing down and stopping your vehicle. You should have the same resistance each time you depress the pedal.
