  • Sub-arterial streets
  • Collector streets
  • Local streets

1. Expressways

The city roads which are reserved for motor traffic with full or partial control access and are provided with grade separation at intersections are called expressways. These are generally constructed to have direct connection between major points of traffic generation in industrial or commercial or business districts. Along expressways, the motor traffic attains very high speeds. Neither the loading nor unloading of the goods is permitted on these expressways. Pedestrians too cannot cross the expressways.

2. Arterial Streets

The city roads which are meant for through traffic usually on a continuous route are called arterial streets. Arterial streets are generally spaced at less than 15 km in developed business centres whereas in less important areas, these may be 8 km apart. Arterial roads are also divided highways with fully or partially controlled access. Parking, loading and unloading are carefully regulated. Pedestrians are permitted to cross them at intersection only.

3. Sub-arterial Streets

The city roads which provided lower level of travel mobility than arterial streets, are called sub-arterial streets. Their spacing may vary from 0.5 km in central business districts to 3 to 5 km in sub-urban areas. Loading and unloading are usually restricted. Pedestrians are allowed to cross these highways at intersections.

4. Collector Streets

The city roads which are constructed for collecting and distributing the traffic to and from local streets, and also to provide an access to arterial and sub-arterial streets, are called collector streets. These are located in residential, business and industrial areas. These roads are accessible from the buildings along them. Parking restrictions are few and that too during peak hours.

5. Local Streets

The city roads which provide an access to residence, business and other buildings, are called local streets. The traffic carried either originates or terminates along the local streets. Depending upon the important of the adjoining areas, a local street may be residential, commercial or industrial. Along local streets pedestrians may move freely and parking may be permitted without any restriction.
