Roads

This article will explain how the EAC road network can be matched Waze road types.

Rwandan Road Network

The Rwanda Transport Development Agency (RTDA) technically decribes the Numbered Roads (PDF).

National Roads (NR)

• Starts with "NR" (used to be "RN")
• These routes connect the different districts
• Tends to run through multiple provinces.

District Roads (DR)

• Starts with "DR"
• Major roads linking main localities in a District.

We will try to follow the RTDA numbering in Waze, even if sometimes the road signs have not been adapted yet. When a road sign shows an older number, It will need to be adapted in WME so the user is not confused.

Other roads

Most of minor roads does not have any road number. In the main cities, Street naming system is in place.

Highways  

A highway is an arterial road, much like the pulmonary arteries (main veins at the heart). They serve a dual purpose:

• carry traffic over long distances between towns, and
• carry traffic from collector roads to freeways, where applicable.

Rwanda has a few numbered highway systems, which are called "numbered routes".

Waze's definition of "highways" includes all these, but it also includes other roads that are not necessarily a part of any numbered route. In other words, think of the dictionary definition of "highway" ("a main road, especially one between towns or cities") rather than the legal definition of the term.

Waze distinguishes three classes of highway: Freeway, Major Highway and Minor Highways.

	Freeway (Fw) Motorways International Trunk Roads Only tarred/asphalted roads KE 🇰🇪 : A roads (tarred) RW 🇷🇼 : NR 1 to 4 UG 🇺🇬 : M roads, Major tarred A roads
	Major Highway (MH)  Other trunk roads Mainly tarred roads. 2x2 roads in main cities (if not classified as Freeway) KE 🇰🇪 : A roads (untarred), B roads (tarred) RW 🇷🇼 : other NR (tarred) UG 🇺🇬 : other A roads (tarred)
	Minor Highway (mH) Unpaved NR (with the "unpaved" checkbox checked) paved DR Major 1x1 roads in main cities KE 🇰🇪 : B roads (untarred), C roads RW 🇷🇼 : DR (tarred) NR (untarred) UG 🇺🇬 :
	Ramps (Rmp) Ramps connect other road types to Motorway/Expressway between the terminal ends of the freeway, at an obtuse angle, and is a 1-way direction. They should only connect any road type to Major/Minor Highways where the slip way is long and at an obtuse angle from/onto the Major/Minor Highway types. ⚠️The "Ramp" road type should never be used as At-grade connectors for creating slip ways; instead the same road type the slip way connects to should be used.

Streets

"Collector roads" are all road types lower than highways, namely streets and primary streets which collects the traffic onto the highway to the freeway. Again, think about your body's vein network. 

	Primary Streets (PS) Paved avenue in main cities which are not highways. Roads that are not highways and are heavily used. Generally be the fastest route you would take to travel through a sector. Primary Streets that are unpaved but that are well defined (as is often the case in rural areas) are to be marked as street type but with the "unpaved" checkbox checked. Used for Unpaved DR (with the "unpaved" checkbox checked)
	Streets (St)  Any road that does not fit into the categories above, is a street. Streets that are unpaved but that are well defined (as is often the case in rural areas) are to be marked as street type but with the "unpaved" checkbox checked.
	Narrow Streets (NS) for narrow street where only motos/bodabodas can go. Street too narrow for a normal sized car.
	Off-Roads / Not maintained (OR) There is a bigger penalty for the road type "Off-road / Not maintained". Road is in a very bad state Roads to be used only be used if no other routing option exists. Private farm roads and trails that are used exclusively as 4x4 trails should preferably not be mapped. They provide no functionality for the general commuter and will not be routed over.
	Private Roads (PR) Roads that are restricted, for local traffic only or not accessible to the general public. Some complexes have multiple entrances that connects to the national grid at opposite ends, and if they are not marked as Private Roads, Waze will incorrectly attempt to route people through there.
	Parking Lot Road (PLR) used to map parking lots for shopping centers and Parkades. It is strongly advised not to clutter the map by drawing every single lane of the parking lot, but just the general exits and entrances and main sections that lead directly to shop fronts. If you map all lanes, do not be surprised if some of your edits are deleted by Area Managers. Parking lot roads are especially useful to 'offload' false traffic jam information when parking lots are close to main roads and Waze might think you are stationary on the main road. Parking lot roads are also used to map fuel stations.

Non drivable road

• Walking Trail
• Pedestrian Boardwalk
• Stairways
• Railroads
• Runways

Railroads may serve as landmarks. Ensure that you never connect any of these to the normal road network, as Waze will attempt to route traffic across these roads if they are connected to normal drivable road types. The general standard is to set 'Railroad' road types to ground level unless elevated over or under a road (change to applicable level). Negative levels are only to be used when the segment is actually below ground level.
