Intersection Atlas
Browse plan-view sheets for signalized four-ways, all-way and two-way stops, T-junctions, mid-block crosswalks, mini-roundabouts with splitters, and school zones—lane counts, control type, and labeled conflict points.

Curb Crossing Desk
A pocket field desk for reading real intersections—atlas plans, curb-to-curb timing math, before-you-step checks, and gap drills—so you decide where and when it is honest to cross.
Plate 01 Why a desk, not a game
Curb Crossing Desk is an offline pedestrian reference and trainer for walkers, parents coaching kids, older adults refreshing curb skills, mobility coaches, and anyone new to a city’s streets. You open seeded plan-view intersections—signalized four-ways, two-way stops, T-junctions, mid-block marked crosswalks, roundabout splitters, school-zone crossings—inspect markings, curb ramps, median refuges, and sight-line blockers, then compute walk and clearance time from width and pace. Run a before-you-step checklist, save named routes with notes on hard crossings, and work static gap-judgment and turning-conflict cards that show the distance/time reasoning without scores, streaks, or accounts. Brass-and-slate chrome, calm diagrams, on-device only—judgment practice before the curb, not a traffic toy.

Plate 02 Instruments on the desk
Six reference tools arranged like a field folio—read the plan, measure the curb, check the step, then drill the gap.
Crosswalk & Refuge Detail
Inspect parallel vs ladder markings, curb ramps and truncated domes, median islands, daylighting setbacks, and blockers like parked vans or hedges—with callouts on what each changes for a walker.
Curb-to-Curb Timing Desk
Enter width, lanes, and pace (adult, child, older adult, or custom ft/s) to read crossing distance, minimum walk interval, and clearance time on a simple phase bar.
Before-You-Step Checklist
Signal state, left-right-left, turning-vehicle scan, phone down, stroller spacing, night/rain visibility—mark each item before an optional local practice reminder.
Gap & Turning Drills
Static scenario cards: pick the honest gap from distance and speed, then reveal the worked math. Turning-conflict cards cover right-hook, left-cross, slip lanes, and blocked crosswalks—no points or prizes.
Named Routes & Conditions
Save offline walks (home→bus, school→library) with crossing pins, hazard notes, and atlas links. Dusk, rain, fog, glare, or crowds adjust pace assumptions and surface a caution strip for the session.
Plate 03 A quiet session at the curb
Open the atlas, study the geometry, then carry the checklist to the sidewalk—nothing phones home.
- Open a seeded plan. Choose a four-way, T-junction, mid-block, roundabout splitter, or school-zone sheet and read lane counts and control type.
- Inspect markings and blockers. Note ladder bars, median refuges, curb ramps, and sight-line clutter before you trust the paint alone.
- Run the timing desk. Set curb-to-curb width and walking pace; read walk interval and clearance on the phase bar.
- Work a gap or turning card. Judge the honest gap from distance and closing speed, then reveal the worked reasoning—no scoreboard.
- Pin a named route. Save home→bus or school→library with notes on the hard crossings and condition flags for dusk or rain.
