A grid road network plan is proposed for the new Amaravati Capital city. The grid network comprises roads designed and classified based on functions and capabilities.
4 classifications of roads were identified and used as the major classes of roads in the Master Plan. They are:-
• Urban Expressway
• Sub-arterial, and
Unclassified roads such as local and access roads are not identified at Master Plan level, however detailed guidelines for local roads should be prepared to guide developers during development control. The proposed grid network will also be sub-categorised based on the level of social interaction, in line with international practice to create streets for people in urban settings.
Road Network Plan :Urban Expressways
Two urban expressways, which connect NH5 and NH9, are proposed to serve the Capital city.
The main urban expressway will provide circulation along the fringe of the city, therefore allowing through-traffic to bypass the Capital city Core.
A semi-expressway will provide a traffic route from the main urban expressway to the CBD
Speeds along urban expressway are generally high to minimise travel time along the expressways
Major Industrial Zones to be located near the expressways.
Road Network Plan :Arterial Road Network
An arterial and sub-arterial network is developed to ensure mobility between the major areas within the City i.e. CBD, commercial zones, major townships and transport hubs.
The arterial network also serves as the major transit corridors, especially for rapid transit systems
The sub-arterial network supports the arterial network, and is the primary access to township development zones
Infrastructure mains are to be located within or adjacent to the arterial network to ensure access to utilities
Traffic speeds along arterial roads should be maintained at 40-60kmh.
Road Network Plan :Collector Road Network
The collector road network is the main distributor of traffic at neighbourhood level.
Access to developments are to be gained from the collector roads.
Access and Local roads are to be connected to the collector road network
Collector roads are to be generally designed for higher social interaction, and therefore speeds should be limited to no more than 40kmh, depending on context.
Village Roads are to be integrated to the Collector Road network
Road Network Plan :Standard Road Elements
The road elements for these road cross-sections need to cater for all users.
In the expressway and arterial roads, the cross-sections should cater for higher vehicular volume, whereas in the sub-arterial and collector roads, emphasis should be given to the public and non-motorised transport users, particularly pedestrians and cyclists, and bus and rapid transit riders.
For the purposes of this master plan, the road widths for the defined roads are set.
Road cross-section standardisation can help to ensure road elements are included at this master planning level. To do this, road design guidelines have been developed for use in the master plan. These guidelines may be further refined based on the local authority’s requirements.
