Interactively plan, construct, manage, and view simulated ridership of your own transit network for cities with my transit simulator!
1. Route Planning & Construction
- Drafting Mode: The game separates "Planning" from "Building." You must click "Create New Route" to enter a drafting mode where you can experiment without spending money.
- Point-and-Click Plotting: You build routes by clicking on the ground. The system automatically finds the shortest path along the road network between the points you select.
- Smart Snapping (Ghost Marker): When hovering the mouse over the map in drafting mode, a transparent "ghost" sphere appears, indicating exactly which road intersection or node the route will snap to if you click.
- Draft Interaction:
- Add Point: Left-click to extend the route.
- Move Point: Click and drag existing yellow markers to adjust the path dynamically.
- Draft Statistics: While planning, you see real-time estimates for:
- Length: Total distance of the route.
- Cost: Construction cost (track/road upgrades) + Fleet cost (buses required).
- Est. Riders: Projected daily passengers based on the population density near your stops.
- Commit or Discard: You can finalize the route (spending the money) or discard the draft to cancel.
2. Route Management
- Active Route List: A sidebar lists all currently operating transit lines.
- Color Customization: You can click the colored box next to any route number to pick a custom color for that line and its vehicles.
- Editing: You can click the "Pencil" icon to edit a route. Note: This deletes the existing route and puts its nodes back into "Draft Mode" for you to redraw.
- Deleting: You can permanently remove a route to clear clutter (though construction costs are sunk).
3. Economy & Simulation
- Budget System: You start with a fixed amount of capital ($1,000,000). You must manage construction costs against your remaining funds.
- Daily Income: Every in-game "Day," you earn cash based on the total ridership across all your lines (Ticket Sales).
- Floating Feedback: When a day passes, floating green text appears over the UI showing exactly how much cash you just earned.
- Ridership Logic: Ridership is calculated based on "Synergy"—connecting Residential areas (Population) to Commercial/Industrial areas (Jobs).
- Public Approval: A percentage score (0-100%) that tracks how happy the city is. This is calculated based on how many buildings are within walking distance (approx. 600m) of your transit stops.
4. Visuals & Map Modes
- 3D City Rendering: The map features extruded 3D buildings, water bodies, parks, and a road network.
- Vehicle Simulation: Small blocky buses travel along your constructed routes in real-time.
- Data Views: You can toggle the map visualization to help plan better routes:
- Standard: Default visual look.
- Zoning Density: Colors buildings by type (Purple for Residential, Blue for Commercial) and intensity (darker colors = higher density/more potential riders).
- Transit Coverage (Approval): A heat map showing service coverage. Buildings turn Green if they are close to a stop, Yellow if they are borderline, and Red if they have no transit access.
5. System Features
- Save/Load System: You can save your current city state (routes, budget, day, approval) to a local JSON file and load it back later to continue playing.
- UI Toggling: The entire interface can be hidden/shown via a hamburger menu button for cinematic screenshots.
