Engineering is responsible for the analysis of traffic delays, coordination and review of traffic impact studies, investigation of requests related to traffic calming (speeding, signage requests, parking restrictions, etc), design and review of traffic circulation facilities, maintenance of traffic volume data, coordination of long-range transportation planning projects, maintenance of the City’s Thoroughfare Classification Map and managing the City's traffic signal and street light maintenance contractors.
Engineering utilizes a RADAR-based traffic counting device to discretely measure the average daily traffic (ADT) volume on select roadways. This traffic volume data is stored in the City's Geographic Information System (GIS).
Thoroughfare Classification Map
Engineering maintains a map of the City’s transportation infrastructure that displays each roadway according to its functional classification. Roadways are classified according to their traffic volume, speed, and type of adjacent development. There are six main classifications of roadways identified by the City:
- Major Arterial. These routes serve regional transportation needs for traffic entering and exiting the city and between major activity centers within the city. Example: US Route 14.
- Minor Arterial. These routes interconnect and supplement the major arterial routes, accommodate moderate trip lengths, and service activity centers. Example: Ackman Road.
- Major Collector. These routes serve as intermediate links between major arterials and points of origin or destination by providing access and traffic circulation within residential neighborhoods and commercial areas. Example: Golf Course Road.
- Minor Collector. These roads connect smaller access streets and residences to the main roadway network (major collectors and arterials). Example: Dole Avenue.
- Local Street. These roads serve to provide access to residential neighborhoods and commercial areas. Example: Caroline Street.
- Alley. An alley (residential or commercial) is a very low volume road designed to provide access to the rear or side of a lot including solid waste and fire access. Alleys are not intended to carry a significant volume of through traffic.
