Walking is the most natural mode of transportation. It is available everywhere and is usually the first and last part of a journey, whether long or short. We have developed an area-based approach for computing the paths and reachability for pedestrians, calculated to an accuracy of just a few meters. We use heterogeneous data sources and can even model desire paths which are not explicitly mapped in the base data. In particular, we do not rely on a consistent routing network.

Notes de l'éditeur
- Planners also use the term «accessibility» instead of «reachability».
- Reachability analysis is obviously useful for shopping areas analysis (top left), but also for maintenance works planning (top right) or service point design (bottom right). Would you install a service point in the middle of desert (bottom right)?
- First we would like to introduce the concept of (precise) isochrones. We start our walk anywhere at any point of a map (Europe, USA, … anywhere where we have street map data) At the starting point, we simultaneously send thousands of virtual pedestrians to any direction. Along their paths, they measure their walking time and their positions. In the end, the walking time is color-coded on the map.
- The definition of walking time obviously depends on the subject: Younger women, older men, people with disabilities, etc. It is possible to precisely model the walking time based on customers’ rules for the the underlying topography and the elevation of the neighborhood.
- Our service can solve a range of customer problems, three of them are outlined below: Quality of Service Coverage for Public Transportation For assessing the coverage quality of your public transportation network, it is important to have accurate data on passenger walking distances to and from the nearest station. An additional factor is whether the closest station is a high-frequency train-station or a low-frequency bus stop. Based on up to tens of thousands of public transport stations, we calculate high-resolution quality grade zones based on the proximity and frequency of public transport stops. Real Estate Rating As a real-estate professional you know that the top three priority items in your business are: location, location, location. A large element of the location’s value is the proximity of local services such as shops, schools, recreation areas, services and public transport. With our walk-time analysis and grading, we can provide up-to-date and accurate indicators for the accessibility of local services. Do you manage millions of properties? No problem! We’ll take care of it thanks to our scalable computation infrastructure. Accurate Nearby Searches Usually, the proximity of these points of interest is based on a simple circle around your current position. With Walkalytics, you are only shown amenities that are genuinely within walking distance – not across the river, on the other side of the highway or blocked by other obstacles.
- Up to now, the local governments only roughly estimate the quality of service by drawing circles around transportation stops (see image).
- Using the Walkalytics approach (see image), the QoS map becomes much more accurate. Compared to the traditional approach, we can show that up to 46% of the buildings in a Swiss city are currently misclassified.

- What are some of the advantages of our approach to computing isochrones for your business or agency? Worldwide coverage, offering a homogeneous result for everywhere. Very detailed results: With one computation, we can show the area that is accessible from any given point within any given timespan, not only for few discrete time steps. We don’t need routing-capable data, we just model every patch of your neighborhood based on its walkability. We can easily combine multiple data sources to model the walkability, like national mapping data, cadastral or surveying data, municipal data, and e.g. OpenStreetMap. Combining data sources for best coverage is easy. This flexibility of adopting to, and using, different data sources has proven tremendously helpful in recent projects. It’s fast, especially considering the information value of the result: Computing one isochrone at 5 meters resolution with an upper limit of 20 minutes of walking, we analyse literally thousands of individual paths and get hundreds of thousands of walking time measurements as a result. And all this information still can be computed in much less than a second on an ordinary laptop.
