Collector roads can vary widely in appearance. Some urban collectors are wide boulevards entering communities or connecting sections. Others are residential streets, which are typically wider than local roads, although few are wider than four lanes. Small-scale
commercial areas can be found on collector roads in residential areas. Key community functions such as
schools,
churches, and
recreational facilities can often be found on collector roads. A collector road usually consists of a mixture of
signaled intersections,
roundabouts,
traffic circles, or
stop signs, often in the form of
four-way stops. Two-way stops are generally used at intersections with local streets that favour traffic movement on the collector. In North America, a collector road normally has traffic lights at intersections with arterial roads, whereas roundabouts and two-way stops are more commonly used in Europe.
Speed limits are typically 20‑35 mph (30‑60 km/h) on collector roads in built-up areas, depending on the degree of development and frequency of local access, intersections, and
pedestrians, as well as the surrounding area (the speed tends to be lowest in
school zones).
Traffic calming is occasionally used in older areas on collector roads as well. == Development ==
