Highways and freeways have a limited number of road entrances and exits and typically don't have stop-and-go traffic signals.
Minor arterial roads usually have stop-and-go traffic signals to accommodate crossing roadways and adjacent land uses, such as shop- ping centers and office buildings.
Driveways for homes and business may connect directly to the roadway, and pedestrian street crossings with traffic signals are located at regular intervals.
These streets have the lowest speed limits and typically have frequent street crossings that use stop signs (and other signage) instead of elec- tronic traffic signals to control the flow of motorized traffic.
For example, Toronto's extensive streetcar system includes rail paths that run down the middle of the street and requires streetcars to obey traffic signals at intersections with cars and trucks.
