Mappy has long been associated with car route planning. Since the acquisition by RATP completed in 2021, the platform is gradually integrating the bus networks of the Île-de-France region with schedules derived from Île-de-France Mobilités data. This evolution changes the game for users looking for a reliable bus route without having to rely on Google Maps.
Bus data on Mappy: what the acquisition by RATP has changed
Before 2021, Mappy relied on generic GTFS format data to offer public transport routes. The bus schedules displayed corresponded to theoretical grids, often misaligned with real-world conditions, especially in densely populated areas.

Since joining the RATP group, the platform utilizes the theoretical schedules and connections from Île-de-France Mobilités. RATP Bus, Noctilien, and T Zen lines benefit from a higher level of accuracy than what the old system provided. Intermodal connections (bus to metro, bus to tram) are calculated using more recent data.
To find a Mappy bus route, you need to select the “public transport” mode from the homepage or the mobile app. The calculation then displays the available bus lines, connection times, and intermediate stops. However, real-time coverage remains uneven depending on the networks and regions.

Mappy bus route: setting up the search for a relevant journey
Simply entering a starting point and a destination is not always enough to get the best bus route. Mappy offers several options that directly influence the result.
Selecting the right mode of transport from the start
By default, Mappy displays the fastest route, which often favors the metro or RER in Île-de-France. To force a bus route, you need to ensure that the “public transport” filter is active, then review the alternative suggestions listed under the main route. 100% bus routes rarely appear as the first suggestion, especially when a combined route is shorter.
Adjusting the departure or arrival time
Bus schedules vary significantly depending on the time slots. A route calculated at 2 PM may propose three connections, while the same route at 8 AM requires only one. Mappy allows you to set a desired departure or arrival time. This setting modifies all the displayed suggestions.
- Select “Depart at” to set the departure time and see the first available buses after this time slot
- Use “Arrive before” so that Mappy calculates the necessary departure based on frequency
- Check the displayed schedules: in the evening and on weekends, some lines operate on reduced frequency, which lengthens the journey without the interface clearly indicating it
The available data do not always allow for conclusions about the reliability of the displayed schedules outside of Île-de-France. Feedback from the field varies on this point, particularly for medium-sized city networks.
Sharing a Mappy bus route: real options and their limits
Calculating a good route is only useful if it can be shared with the person who will take it. Mappy offers several sharing mechanisms, but not all work the same way.
Sharing via URL link from the browser
On the web version, once the route is displayed, the URL in the address bar contains the route parameters (departure, arrival, mode of transport). Copying this URL and sending it via messaging or email allows the recipient to find the same route. The link retains the “public transport” mode if it was selected at the time of calculation.
This method remains the most reliable for sharing an accurate bus route. However, if the schedules change between the time of calculation and the recipient’s consultation, the displayed results may differ.
Sharing from the mobile app
The Mappy app includes a share button that generates a short link. This link can be sent via messaging apps installed on the phone. The recipient opens the link in their browser or in the Mappy app if they have it installed.
- The shared link directs to the route with the same departure and arrival parameters
- The selected mode of transport is retained in the link
- A screenshot remains a quick alternative when the recipient does not need to modify the route
- Saving the route in favorites (via a Mappy account) allows it to be found without having to redo the search
A free Mappy account is sufficient to save routes and access them from another device. Creating an account also allows you to set a home address and a work address, which speeds up recurring searches.
Mappy’s visibility against Google Maps: the effect of the Digital Markets Act
Since March 2024, the Digital Markets Act (DMA) prohibits Google from automatically promoting Google Maps in its search results in Europe. This measure, documented by Clubic for Google Maps, opens up visibility space for alternative route planners like Mappy.
For a user typing “bus route” into a search engine, the results now display a variety of services where Google Maps previously held the top visual position. Mappy, as a French service backed by RATP, finds itself better positioned in this new regulatory context.
The concrete impact on Mappy’s traffic remains difficult to measure publicly. Conversely, the fact that the platform utilizes data from the National Access Point France Mobilités for real-time traffic and public transport enhances the relevance of its bus results, at least within French territory.
The calculation of bus routes on Mappy has gained precision with the backing of RATP and Île-de-France Mobilités data. Sharing via URL remains the most direct method for transmitting a route. Coverage outside Île-de-France is improving, but the reliability of schedules still depends on the local network concerned.
