The roadways located in Granville have been categorized according to their functional and operational intent. The categories are based on maintaining the roadway’s function in terms of capacity, traffic flow, property access, and safety. The functional descriptions of the six basic categories are as follows:
(a) Category I: Designed and intended to provide mobility for high volumes of traffic at high speeds over long distances. Highways in this category are typically designed and intended to achieve a minimum posted speed of 55 mph. All interstate and freeway facilities are included in this category.
(b) Category II: Designed and intended to provide mobility for relatively high speed, high volume, and long distance through traffic. Highways in this category are typically designed and intended to achieve a minimum posted speed of 50 mph in areas without signals and 45 mph in areas with signals. This category includes arterials of state-wide significance and this is the highest category allowing at-grade intersections.
(c) Category III: Designed to provide mobility at moderate to high speeds and volumes. Typically, Category III highways provide for a minimum posted speed of 45 mph in areas without signals and a minimum of 35 mph in areas with signals. Arterials outside the urban area are included in this category.
(d) Category IV: Designed and intended to provide access and mobility at moderate to high speeds and volumes for moderate to short distances in rural areas and low to medium speeds and volumes in urban areas. Low to moderate speed arterials within the urban area and major collectors are included in this category. Typically, Category IV highways provide for a minimum posted speed of 35 to 55 mph in undeveloped areas and 25 to 45 mph in developed areas.
(e) Category V: This category applies to roads and streets designed and intended to take traffic from local roads, carry it a short distance, and distribute it to higher category roadways. Minor collectors and neighborhood collectors are included in this category. Typical posted speeds are 25 to 35 mph.
(f) Category VI: This category applies to local streets that provide access to individual properties that abut the street.
