RealHighway Mod

Technical specifications for the RealHighway Mod are located here. This page shows values, attributes and level of compatibility with other components of the NAM that are useful for end users and developers alike.

Refer to the RealHighway (RHW) Feature Guide to understand how to use these components.

The documentation on this page is in progress.
The contents of this document are undergoing revision and are subject to change.

Key

Yes	This feature can be constructed, with minimal (if any) limitations.
Partial Support	This feature can be constructed, but not in all instances. Details will be given as to what is/is not possible. Partial support could be due to intentional design reasons (including realism or general infeasibility), or simply because the feature has not been fully developed.
Limited Support	This feature can be constructed, but only in extremely limited circumstances. Instances that are possible may be listed, insofar as it is possible. Use at your own risk.
No	This feature cannot be constructed. This restriction could be due to intentional design reasons (including realism, general infeasibility, or game limitations), or simply because it has not yet been developed.
—	This feature is not applicable.

OxO	Stands for 'Orthogonal x Orthogonal', and refers to a situation where both networks are orthogonal (in a straight line) along the game's grid, intersecting perpendicularly (at a 90° angle)
OxD	Stands for 'Orthogonal x Diagonal', and refers to a situation where the base network is orthogonal (in a straight line) along the game's grid, and the cross network is diagonal (running at a 45° angle).
DxO	Stands for 'Diagonal x Orthogonal', and refers to a situation where the base network is diagonal (running at a 45° angle), and the cross network is orthogonal (in a straight line) along the game's grid.
DxD	Stands for 'Diagonal x Diagonal', and refers to a situation where both networks are diagonal (running at a 45° angle) along the game's grid, intersecting perpendicularly (at a 90° angle).

Capacities and Speeds

The capacity of each network depends on the Traffic Plugin one has installed. Capacity is generally calculated on a per tile basis by the game, as the game cannot read the number of lanes.

RHW Network Type^1,2	Classic	Low	Medium	High	Ultra
MIS Ramps (single-tile capacity)	3000	6000	10000	15000	30000
RHW-2 (single-tile capacity)	3000	6000	10000	15000	30000
RHW-3 (single-tile capacity)³	3750	7500	12500	18750	37500
RHW-4 (dual-tile capacity)	6000	12000	20000	30000	60000
DDRHW-4 (single-tile capacity)³	3750	7500	12500	18750	37500
RHW-6S (dual-tile capacity)³	7500	15000	25000	37500	75000
RHW-6C (triple-tile capacity)³	11250	22500	37500	56250	112500
RHW-8S (quadruple-tile capacity)³	15000	30000	50000	75000	150000
RHW-8C (triple-tile capacity)³	11250	22500	37500	56250	112500
RHW-10S (quadruple-tile capacity)³	15000	30000	50000	75000	150000
RHW-12S (quadruple-tile capacity)³	15000	30000	50000	75000	150000

¹ The capacities listed are for the full width of the network, rather than the per-tile capacity.
² These figures also apply to all elevated versions of each network width. This means that the L0 RHW-4 has have the same capacity as its L1, L2, L3, and L4 counterparts.
³ Networks with crossover paths (RHW-6C, RHW-8S, RHW-8C, RHW-10S, and RHW-12S), and those that use a special workaround (RHW-3, DDRHW-4, and RHW-6S) have a 25% boost on capacity over the normal per-tile figure for the base RHW network. This boost can only be applied once, which is why DDRHW-4, despite having one more lane than the RHW-3, has the same capacity. A similar situation exists with the RHW-6C and RHW-8C, and the RHW-8S and RHW-10S.

The catalog speeds for the base RealHighway network are listed below. These speeds apply when the network is at 100% capacity; speeds on empty networks will exceed these figures by 30%, declining as the networks increase in volume per the Congestion vs. Speed Curve.

Vehicle Type	Speed
Car	150
Bus	150
Freight Truck	130
Pedestrian¹	10

¹ Pedestrians are only permitted on the L0 RHW-2 network.

FLEXWidth Transitions

The availability of these transitions mirrors the available heights for each network, with the exception of RHW-2 → RHW-4 and RHW-3 → RHW-4 which are L0 (ground-level) only. All networks involved in the transition must be at the same height level.

S-to-C Transitions support asymmetrical combos, so additional possibilities exist beyond what is strictly indicated on this table. The only limitation is that each network has the same number of lanes or differ by only one lane per side. For example, RHW-6S (3 lanes per side) can transition to RHW-4 (2 lanes per side), RHW-6C (3 lanes per side), and RHW-8C (4 lanes per side).

Network ID Assignments

The RealHighway Mod uses the following ID ranges:

Network Range	Purpose
`0x5700 - 0x57FF`	Current RHW range
`0x7700 - 0x77FF`	LHD Path remapping range

Within the Network Addon Mod, the RealHighway Mod occupies the entire 0x57 range.

There are some Flex FARHW pieces in the 0x56F range, and there are also a handful of legacy RHW puzzle pieces in 0x5E.
