Chicanes (sha KANES) usually consist of a series of bulbouts or curb extensions that narrow the street to one lane at selected points and force motorists to slow down to maneuver between them. Such treatments are intended for use only on residential streets or quiet portions of a downtown with low traffic volumes (under 1,500 cars per day), where it is desirable to greatly restrict vehicle speeds and movements.
Estimated cost: For a set of three, $10,000 to $20,000.
- Reducing vehicle speeds on long blocks (over 500 feet).
- Adding greenery and visually narrowing appearance of street.
- Creating a park-like environment.
- Assuring 20-foot opening for fire truck operations.
