glare recovery
What type of pedestrian are the slowest?
Handicapped pedestrian
How many classes of vehicles are there based on AASHTO?
four (4)
This type of resistance acts on a vehicle in motion due to air in front of it and the friction of air around it.
air resistance
How many classification of highways are there based on the road characteristics?

These bicyclists use mainly residential streets that provide access to schools, recreational facilities, and stores.
Class C bicyclists
The maximum gross allowable vehicle weight on interstate highways is this many pounds?
80,000 lbs
The resistance caused mainly by friction between the pavement surface and tires, and by friction in the vehicle’s moving parts.
rolling resistance

stopping sight distance (SSD)
Enumerate the perception-reaction process in order

What class is an experienced and skilled cyclist who uses a pedal-assisted electric bicycle (E-bike), confidently navigates roads alongside motor vehicles, follows traffic regulations, and safely performs turning, merging, and lane-changing maneuvers.
Class A
What is the meaning of AASHTO?
American Association of Highway and Transportation Officials
the distance the car travels from the point when you start braking until the car stands still
braking distance
How many percent through service is accounted for Freeway (Limited-Access Facilities)?
100%
the time it takes for a driver to notice a hazard, understand the situation, decide what to do, and physically react. For example, when a pedestrian suddenly crosses the road, the driver must recognize the danger and decide to apply the brakes before actually braking.
Perception-Reaction Process
