Mechanicsburg Sizing Standards
Certain parts of a city need to be standardized in order to create consistency. The following sections lay out these guidelines so that Mechanicsburg will make a coherent whole.
Roads which would likely get heavy traffic at all times of day, such as downtown's main avenues and boulevards, should be two (typically) or three lanes (in special cases) in both directions. All lanes should be 4 blocks wide of asphalt. Lanes of the same direction should be separated by 1-wide dashed yellow lines, and lanes of opposing direction should be separated by 1-wide solid yellow lines. Optionally, major roads may have a decorative 3-wide grassy median. Major roads must have a 3-wide half-step sidewalk. Medians may need a small pedestrian island for crosswalks.
Roads which would likely get heavy use at peak hours and moderate use at all other hours, should be one lane in each direction. All lanes should be 4 blocks wide of asphalt. Lanes will be separated by 1-wide solid yellow lines. Main roads must have a 2-wide half-step sidewalk. Main roads will generally have stop lights, but may have stop signs if the intersection is 3-way or 2-way.
Roads which would not likely be exposed to heavy use, but would likely get some use at all times, such as in residential areas should be two lanes - either one lane in each direction or both lanes the same for a one-way street. All lanes should be 4 blocks wide of asphalt. Lanes will be separated by 1-wide solid yellow lines if two-way or a 1-wide dashed yellow lines. Minor roads may optionally have a 1-wide half-step sidewalk. Minor roads will only have stop signs, not stop lights.
Roads which would often go unused should be 7 blocks wide of asphalt if two-way and 4 blocks if one-way. Alleys should not have sidewalk.
Some roads may have additional lanes to serve specific purposes. They will always be the right-most lane in their direction, and no road will have more than one special lane at a time. In order to maintain consistency in spacing of roads, these lanes will cut into allocated block space rather than widening the to which they are attached.
Major and main roads may be on a bus route. These lanes are essentially a place for the bus to come to a stop while loading/unloading passengers. Moreover, they should only be placed outside important city locations as they will form the basis of the city's VoxelPort system. All bus lanes will be 5x10 or 10x5, depending on orientation. They will be separated from the main lanes of traffic by a 1-wide solid blue line.
Main and minor roads may have some on-street parking. Main roads will likely have parallel parking, whereas minor roads might have perpendicular parking. All parking spaces should be 3x5 or 5x3, depending on orientation. Parking spaces should be outlined (with a gap in the side facing traffic lanes) with 1-wide white lines for regular parking or 1-wide blue lines for handicapped parking.
In order to maintain an orderly grid layout, city blocks will conform to the following standards. There is the possibility that that with the permission of Giltwist (eventually a zoning commission) blocks of the same zoning may be merged for particularly large builds. Similarly, a block may have an alley placed within it to allow access to otherwise hard-to-reach builds. As a final note, it is understood that as roads downgrade as they move outwards from city center or as terrain fluctuates, there may be some slight variations in the exact size of blocks, particularly near transitions between block types.
From city center, the first 10 blocks in all four directions will be a standard 160x160 separated by Major Roads. Typically, these blocks will not be residential, but exceptions might be made (such as for an Ethnic Town area).
Prominent areas and districts other than Downtown blocks will be 80x80, but will be separated by Main Roads. Typically these blocks will not be industrial but exceptions might be made (such as for a coastal area).
All other blocks will be 40x40 and separated by Minor Roads. These areas will typically not be industrial or commercial and exceptions are unlikely.
