The systems

Nine small parts, each with one job

I build Situ as small systems, made to inform the design of a game (research-creation). Each has one job, a blueprint and its own tests, and I try it in the Lab before the next one may use it. The status word says how far each one stands (what the words mean).

	System	Job	Status	More
	Walking network	Add the city’s off-street paths before space syntax is calculated	verified, by the checks in its report	how it is built
S1	Streets	Which streets connect, and who may use them in which direction	verified	how it is built, checks on photos; in the Lab
S2	Scores	Attach the space syntax values to each street	verified	how it is built; in the Lab
S3	Rules	Stop signs, traffic lights, forbidden turns, speed limits	verified	how it is built, checks on photos; in the Lab
S4	Buildings	What each building is, and where a walker reaches it	verified	how it is built; in the Lab
S5	Rhythm	When the streets are busy, and which places say they are open	verified	how it is built; in the Lab
S6	Streetscape	What stands on the streets: trees, hydrants, lights, cameras, crossings, sidewalks, benches, road works	verified	how it is built; in the Lab
S7	Commuters	How people commute and when, and how far homes are from transit	verified	how it is built; in the Lab
S8	Views	What a walker can see from each point of the streets	verified	how it is built; in the Lab
S9	Observer	Imagines people moving from what the other systems say, and compares them with the counts and space syntax	partial: commuters on foot on a weekday morning; drivers planned	how it is built; in the Lab

Each system has an overview page, which says what it found, and a page on how it is built and tested. The job each one does in a game is on From systems to a game. To follow one number from its source to the Lab, see Tracing a result.

Reading the diagrams

Every blueprint uses the same key. A grey outline is data coming in. A dashed grey one is a decision I made and kept in a file. A white outline is a processing step, and a thick white one is a result written to disk. Pink marks a test.

On the map sheets, labels never overlap. When a label has to move, a thin line points back to what it names.
