A traffic control desk drawn like a technical manual: bone paper, black ink and one orange accent. Every intersection shows a single green direction, and you decide when it flips. The manual's index lists what the desk holds.
p. 02 · Controls
Tap near an intersection to swap its green between the horizontal and the vertical road. A car already past the stop line keeps going, so flipping while it is inside the box sends cross traffic into it. Drivers held too long on red give up, and a warning bar above each car fills first. An assist bulb highlights the intersection worth switching.
p. 07 · Grid, thirty plans
Thirty city plans, from one lone intersection to a nine-box district laid out 3×3. Guide the target number of cars with no collision and nobody giving up. Stars follow the average wait: 1.2 seconds or less for three, 2.6 or less for two. Each cleared plan opens the next.
p. 15 · Shift, endless
A 2×2 district where traffic keeps growing until three mistakes end the shift. The desk keeps a log of your last 20 shifts and flags the record.
p. 21 · Exam
Ten questions per sitting from 22 real facts on the history of traffic lamps, pedestrian crossings and road rules, from London in 1868 to Cleveland, Detroit and the Belisha beacon. A short note follows each answer.
p. 26 · Duty file
Cars guided, switches made, collisions, minutes on duty, plans cleared, three-star plans and the longest shift. Ten stamps to collect, such as Steady Flow and Rush Hour.
p. 30 · Setup
Haptics, the operating manual and a progress reset. Behind the menus a drafting grid scrolls, an orange scan line sweeps and small car strokes slide along the roads; switch Background animation off in Setup for a still page.
