Where several levels of definition are available, this limits the information available to a Wazer new to that part of India.
I propose the following policy, knowing full well that it will take several months to make significant changes and may never be 100% complete.
Freeways: Expressways such as Mumbai-Pune and Vadodara-Ahmedabad (please post here regarding other expressways in your part of India) and also GQ (Golden Quadrilateral) and NSEW (North-South East-West) trunk routes. Possibly include Mumbai's Western and Eastern express highways, Kolkata's Eastern Metropolitan Bypass and some of the Ring Roads in different cities.
Golden quad is a good option. As a start I would say the following
a. At least four lanes
b. Speed limit of 80 KM/h - And it is possible to do that
c. No traffic lights
As per the defn, expressways, and golden quadrilateral qualify but not Mumbai's Western Express Highway, Kolkata's Eastern Bypass. Ring roads may possibly qualify. Use your discretion

a. Speed limit (Or its possible to do) - 60 KMPH
b. Less traffic lights
c. Use your discretion if it passes through a major city. Often it is not possible to achieve a consistent speed of 60 KMPH through a city highway, though you can reach speeds of over 100. Don't consider the F1 types, but nervous drivers like me when thinking of the speed.

All other highways.
Darryl-BHP wrote:Primary Street: Major through routes from one part of a city to another, also well maintained and traveled rural roads.
All roads regardless of speed, which can be considered as the arterial road, and you want to encourage routing through that, to avoid multiple turns. Discretion of the AM
Darryl-BHP wrote:Street: All other roads except private and service roads.
All other roads, except the ones you want to discourage routing through
Parking Lot Roads: Roads you want to possibly discourage routing, and real parking lot roads
Ramp: Roads giving access to a freeway/major highway. You would like to use it to merge / leave a highway, but otherwise discourage routing through it.
Walking Trail: Narrow roads which are walkable, bikable but a car would not ordinarily go in
