**Designing a city transport app** I need to respond to the user’s request for a mini project on finding the shortest route in a city transport network. It’s essential that I follow developer guidelines, ensuring to render the response in a full HTML format without mentioning iframe or external libraries. I should aim for a polished interactive design using Dijkstra's algorithm, allowing users to simulate routes and visualize fare and path information. Ultimately, I want to create an engaging and beautiful user interface!**Creating an interactive transport app** I need to ensure that the app for finding the shortest route in a city transport network is polished but not overly complex. With a strong token budget, I’m targeting a compact codebase of around 600 lines. The app should include full HTML, CSS, and JS, without mentioning iframes. I aim for an intuitive UI using SVG maps with well-named stations, possibly featuring Dijkstra’s algorithm. Aesthetic choices should be pleasing, with a navy rail network and light cream accents, creating a delightful and interactive experience!**Designing transit route features** I need to create a map with colored transit lines, a legend, and a toolbar for zooming, resetting, and recentering on the full network without relying on external resources. The routes should show the fastest options with the fewest stops and the shortest distances as the primary metric. I'll implement Dijkstra's algorithm for the shortest actual route based on weighted distances, allowing users to choose between shortest, fastest, and fewest stops. It’ll include about 16-20 stations and an itinerary feature displaying total distances and algorithm progress with an optional animation toggle. ```html CityRoute — Shortest Route Finder

LESS GUESSWORK. BETTER JOURNEYS.

Your city. Connected.

Find the shortest path through the city, one connection at a time.

Harbor City16 stations · 3 transit lines

DEMO

Plan your journey

Two stops. One well-connected route.

You can also choose stations on the map.

Small network. Smart decisions.

Give every connection a cost

Stations are nodes. Bidirectional tracks are edges with a distance and travel time. Choose distance, time, or number of stops as your priority.

Explore the cheapest next state

Dijkstra expands the lowest-cost unsettled state. We remember both the station and the arriving line, so a line change correctly adds a 3-minute transfer buffer.

Follow the best path back

Once the destination is reached, predecessor links reveal your route. Disabled lines are excluded. All costs are nonnegative, so the chosen priority is minimized.

frontier ← starting station, cost 0
while frontier is not empty:
  current ← lowest-cost unsettled state
  if at destination: reconstruct the route
  relax each available neighboring connection
