๐Ÿ‡ฏ๐Ÿ‡ฒ How JIMS works

Every phone on the road makes Jamaica's traffic map smarter.

JIMS turns ordinary phones and fleet vehicles into anonymous traffic sensors. As people drive, the system measures real road speeds and paints live conditions on the map โ€” no hardware, no sensors in the road, just crowd-sourced movement.

The live traffic engine

From a moving phone to a coloured road โ€” in five steps

Open the map, allow location, and your device quietly helps measure traffic for everyone around you.

Phones become sensors

When you open the map and allow location, your device shares anonymous GPS points โ€” position and speed only. A random probe id is used; it is never linked to your name or account.

Map-matching

Each GPS point is snapped to the nearest road on Jamaica's network, so the system knows exactly which street the vehicle is on.

Speed aggregation

Every 30 seconds JIMS combines all recent points on each road into a live median speed โ€” one slow car can't skew it, but a real jam shows instantly.

Congestion colouring

That speed is compared to the road's normal free-flow speed, and the road is coloured green, yellow, orange or red.

Automatic detection

Sudden, sustained slowdowns raise traffic events โ€” jams and slowdowns appear on the map and in the admin monitor without anyone reporting them.

Reading the map

What the traffic colours mean

Every road on the live map is coloured by how fast traffic is actually moving.

Green โ€” free flowing Yellow โ€” moderate Orange โ€” slow Red โ€” heavy congestion Grey โ€” no live data yet

Grey roads simply have no drivers reporting yet โ€” they fill in with colour as more people use JIMS in that area. The map gets more complete the more it is used.

Beyond colours

Travel times, routing & everything else

โฑ๏ธ Travel times & smart routing

The Jamaica Traffic card shows live travel times for major corridors โ€” Kingston, Spanish Town, Portmore, Ocho Rios, Montego Bay, Mandeville and the highways. Tap any corridor to draw the route end-to-end, with delay sections highlighted.

Search a route between any two places and JIMS returns a traffic-aware ETA built from current road speeds, automatically suggesting the faster way around congestion.

Anyone can report a hazard โ€” crashes, closures, flooding, downed trees. Reports are reviewed by moderators before they appear publicly.

Privacy first

Your data stays anonymous

Traffic data is anonymous. JIMS never needs your name to measure traffic โ€” it only needs movement. You can stop contributing at any time from the traffic card. See the Privacy Policy for the full detail.

The network effect: JIMS gets more accurate the more people use it. Keep the map open while you travel and you help every other road user in Jamaica.
