traffic or pedestrians, whether public or private. Streets are further classified
according to the function they perform. Classifications of streets are as
follows:
A.
ARTERIAL STREETArterial streets are designed primarily to carry traffic and generally should not provide access to land which would interfere with their primary traffic functions. They are designated as "limited," "controlled" or "partial" access streets. Arterial streets serve an unlimited number of dwelling units and unlimited average daily traffic.
B.
CONNECTOR STREETConnector streets collect traffic from collector, minor and local access streets and also provide a connection to arterial streets and expressways and between villages. Connector streets do not normally provide direct access to individual uses. Connector streets serve an unlimited number of dwelling units and unlimited average daily traffic.
C.
COLLECTOR STREETCollector streets gather traffic from minor and local access streets and they feed this traffic to connector and arterial streets and expressways. Collector streets carry heavier traffic volumes than local streets although they also provide direct access to individual uses located along them. Collector streets serve an ultimate 500 dwelling units or up to an ultimate average daily traffic count of 4,000 vehicles.
D.
MINOR STREETMinor streets provide direct access to individual uses or gather traffic from local access streets and feed this traffic to collector streets. Minor streets serve up to an ultimate 150 dwelling units or up to an average daily traffic count of 1,250 vehicles.
E.
LOCAL ACCESS STREETLocal access streets primarily provide direct access to individual uses. They serve to provide the connecting link between the beginning or end point of a trip and the higher categories of streets. Local access streets are further classified as follows:
(1)
CUL-DE-SAC STREETSA cul-de-sac street is permanently terminated at one end by a vehicular turnaround and intersects another street at the other end. Cul-de-sac streets shall not exceed 800 feet in length and shall not ultimately furnish access to more than 25 dwelling units or ultimately have an average daily traffic count in excess of 200 vehicles. (See Figure 3-1.)
(2)
LOOP STREETA loop street intersects other streets on each end and may intersect a cul-de-sac street at some point between each end. A loop street shall not ultimately furnish access to more than 75 dwelling units or ultimately have an average traffic count in excess of 600 vehicles. (See Figure 3-2.)
F.
MARGINAL ACCESS STREETMarginal access streets are minor streets parallel and adjacent to major traffic streets to provide access to abutting properties and control of intersections with major traffic streets. (See Figure 3-3.)
STRUCTURE
