In transportation planning, what is a 'complete streets' policy designed to achieve?
Answer: Design roads to safely accommodate all users—pedestrians, cyclists, transit riders, and motorists
Complete streets policies require transportation networks to be planned and designed for all users and modes, not just automobiles.
What is the typical minimum design stopping sight distance for a road with a 45 mph design speed according to AASHTO?
Answer: 305 feet
AASHTO specifies approximately 305 feet of stopping sight distance for a 45 mph design speed based on perception-reaction time and braking distance.
Which agency oversees the National Highway System (NHS) and provides federal highway funding to municipalities?
Answer: FHWA (Federal Highway Administration)
The FHWA, part of USDOT, administers federal highway funding programs and sets standards for federally funded roadway projects.
What does 'induced demand' mean in the context of highway capacity expansions?
Answer: New vehicle trips generated by the addition of road capacity that would not have occurred otherwise
Induced demand refers to the phenomenon where expanding road capacity generates new vehicle trips, often negating congestion relief over time.
What is the primary purpose of a road diet (lane reduction)?
Answer: Improve safety and multimodal use by repurposing excess vehicle lanes
A road diet converts excess vehicle lanes to uses such as bike lanes, turn lanes, or wider sidewalks, typically improving safety and multimodal access.
Which document must a metropolitan area with a population over 50,000 maintain for federal transportation funding eligibility?
Answer: Long Range Transportation Plan (LRTP) and Transportation Improvement Program (TIP)
Urbanized areas over 50,000 must have a Metropolitan Planning Organization (MPO) that maintains a federally required LRTP and TIP to access federal transportation funds.
