What describes the strategy aimed at preserving the function of local streets by reducing traffic volume, speed, and accidents?

• A. Traffic Calming
• B. Occupancy
• C. Greenshield's Model
• D. Demand

Answer: (A)

Traffic calming focuses on keeping local streets safe and functional for residents by slowing traffic and reducing harmful through-traffic. It uses physical design and policy measures—like speed humps, raised crosswalks, curb extensions, chicanes, and narrower lanes—to lower vehicle speeds, decrease crashes, and discourage cut-through trips. That combination preserves the local street’s character and safety for pedestrians, cyclists, and residents while still serving legitimate local needs.

The other terms don’t describe this approach: Occupancy is a measurement concept related to how much of a road space is filled by vehicles, not a strategy to modify street function. Greenshields’ Model is a theoretical relationship among speed, flow, and density, not a management tactic. Demand refers to the desire or need to travel, not a program to alter speeds or volumes on local streets.
