+# Transit API
+
+Transit API for managing bus routes, navigation, and GPS tracking for bus drivers.
+
+## Project Structure
+
+```
+transit_api/
+├── index.js           # Main API endpoints
+├── middleware.js      # JWT authentication middleware
+├── db.js              # PostgreSQL connection
+├── schema.sql         # Database schema setup
+├── package.json       # Dependencies
+└── .env               # Environment variables
+```
+
+## Setup
+
+### 1. Install Dependencies
+
+```bash
+npm install
+```
+
+### 2. Set Up Database Schema
+
+Execute the following in PostgreSQL:
+
+```bash
+# Via psql command line
+psql -U your_user -d your_database -f schema.sql
+```
+
+Or copy-paste the SQL queries directly into pgAdmin.
+
+### 3. Environment Variables (.env)
+
+```env
+PG_HOST=localhost
+PG_PORT=5432
+PG_USER=your_user
+PG_PASS=your_password
+PG_DB=your_database
+JWT_SECRET=your_jwt_secret
+PORT=5001
+```
+
+Note: `ADMIN_USER_CODES` has been moved to the `auth_api` service. Configure admin user codes in `auth_api/.env` as a comma-separated list.
+
+### 4. Start API
+
+```bash
+npm start
+```
+
+The API runs at `https://transit.xtransit.testinstance.nl`
+
+The service group also includes the Employee API at
+`https://employees.xtransit.testinstance.nl` and the central monitoring
+dashboard. See [`../MONITORING_UI.md`](../MONITORING_UI.md) for health
+checks, error inspection, and the controlled request tester.
+
+## API Endpoints
+
+All endpoints require an `Authorization: Bearer {token}` header.
+
+**GET** `/health`
+
+- Checks whether the deployed transit API is running and the database is reachable.
+- Returns `200` with `{"status":"ok","database":"ok"}` on success.
+- Returns `503` if the API is running but the database is unreachable.
+
+### Schedule
+
+Schedules are weekly templates. Each row in `transit.schedules` represents one
+departure time for one bus line and one `day_of_week`:
+
+- `1` to `5`: weekdays
+- `6`: Saturday
+- `0`: Sunday
+
+Driver assignments are stored separately in `transit.shifts` with
+`(schedule_id, driver_id)`, where `driver_id` references `workers.users(id)`.
+The current `shifts` shape represents the active assignment. To retain different
+assignments for different calendar weeks, add a `week_start` (or assignment date
+range) column and include it in the unique key.
+
+**GET** `/driver/schedules/daily?date=2026-09-18`
+
+- Returns only weekly schedule templates assigned to the authenticated driver through `transit.shifts`.
+
+**PATCH** `/driver/weekly-schedules/:scheduleId/status`
+
+- Updates the status of an assigned weekly schedule.
+
+**GET** `/admin/weekly-schedules`
+
+- Lists weekly templates and their current driver assignments.
+
+**GET** `/admin/shift-drivers`
+
+- Lists drivers from `workers.users` for shift assignment.
+
+**POST** `/admin/weekly-schedules`
+
+- Creates one template. Body: `{ "busLineId": 1, "dayOfWeek": 1, "startTime": "08:00", "endTime": "09:00", "driverId": 12 }`.
+
+**POST** `/admin/weekly-schedules/bulk`
+
+- Creates multiple departures in one transaction. The API derives each end time
+  from the selected bus line duration. Body: `{ "busLineId": 1, "dayOfWeeks": [1,2,3,4,5], "startTimes": ["06:00", "06:30", "07:00"], "driverId": 12 }`.
+
+**PUT** `/admin/weekly-schedules/:scheduleId/shift`
+
+- Replaces the driver assignment. Pass `{ "driverId": 12 }` or `{ "driverId": null }`.
+
+The legacy `/admin/schedules` and `/schedule/daily` endpoints remain for older
+clients, but new clients must use the weekly schedule endpoints above.
+
+**GET** `/schedule/daily?date=2024-05-05`
+
+- Retrieve daily schedule for driver
+- Response:
+
+```json
+{
+  "date": "2024-05-05",
+  "routes": [
+    {
+      "id": 1,
+      "startTime": "2024-05-05T08:00:00Z",
+      "status": "scheduled",
+      "busLine": {
+        "lineNumber": 1,
+        "startStop": "Central Station",
+        "endStop": "Airport"
+      },
+      "busType": {
+        "name": "Standard Bus",
+        "seatCapacity": 50,
+        "licensePlate": "BUS-001"
+      }
+    }
+  ]
+}
+```
+
+**GET** `/routes/:routeId`
+
+- Details of a specific route
+- Response: `{ "route": {...} }`
+
+### Public Schedule Overview
+
+**GET** `/schedules/overview?date=2026-05-06&lineId=1`
+
+- Fetches a date-based overview of scheduled services
+- Weekly templates are selected by `day_of_week` and driver assignments by `shifts`
+- One-off / incidental services are only included on their exact date
+- Filters: `driverId`/`chauffeurId`, `stopId`/`busStopId`, `lineId`, `status`
+- Response: `{ "date": "2026-05-06", "summary": {...}, "schedules": [...] }`
+
+The legacy endpoint **GET** `/schedules` remains available for existing clients.
+
+Example:
+
+```bash
+curl "https://transit.xtransit.testinstance.nl/schedules/overview?date=2026-05-06&chauffeurId=12&busStopId=3"

+  "stops": [
+    {
