Demand cap and neighbor connections

[monkeywater 910]

Consider 2 situations

 

a) a large tile surrounded by 4 large tiles. Each of the 4 large tiles is connected with 2 highway connections, for a total of 8 neighbor connections

b)a large tile surrounded by 8 medium tiles.  Each medium tile is connected with 1 highway connection, for a total of 8 neighbor connections.

 

Will (b) experience greater cap relief, or will they be equivalent?

(b) will have more cap relief as each subsequent connection to the same tile suffers diminishing returns of the cap relief. Someone will likely post a linky to the actual numbers as I'm out of time this morning to find them. (Or if you have the Prima Guide, they are in there.)

@CorinaMarie is correct.  The wiki over at SC4D says nothing about additional neighbor connections other than "Subsequent neighbour connections (to other cities) provide a percentually diminishing CAP relief.", which, based on info provided by the Prima Guide, appears to be wrong. 

According to the Prima Guide, the first neighbor connection of each type to any particular city provides the full value of cap relief.  Subsequent connections of the same type, to the same city, drop the cap relief number.  The second neighbor connection of the same type , to the same city, provides a cap relief value that is approximately 58% of the first connection; the third connection provides a cap relief value that is approximately 70% of the second connection.  I couldn't find any numbers beyond the third connection.  The Prima Guide only says that "...each additional connection of the same transportation type, to the same neighbor offers a diminishing amount of Demand Cap Relief.

The above is valid, whether or not there is an active city (i.e. one that has been initialized) in any particular direction.  Also, it should go without saying that CAP relief is CAP relief, so additional connections are worth having, even if you aren't getting the full value provided by the first connection.

Awesome, thanks!

 

I'm designing a new region, so I wanted to get my tiles laid out appropriately for max cap relief of what will become a huge central city

Keep in mind each different connection also adds cap relief such as road, rail, avenue, and subway.
