This is a demo of the Manhattan router used at Ramboll for pedestrian, bicycle, public transport and car routing in various travel demand models, travel time and accessibility calculations and other analyses. Manhattan is used with transport network data from different sources – this demo uses the OpenStreetMap network augmented with data from other sources for bicycle routing in the Helsinki capital region.

Given trip endpoints, the router returns at most three alternative routes. The properties of each route can be viewed by clicking the route. The score of the route is is the amount of times that route is chosen for a sample of 100 individuals. It is thus not a deterministic value, but reflects how alternative routes are handled in modeling.

The Manhattan router is implemented in R and this user interface with Shiny and Leaflet. The router is not optimized for the common web use of finding alternative routes for one trip, but is very efficient for finding routes of millions of trips. This demo is thus not primarily an independent route planner, but a companion piece for large scale analyses of transport networks, mobility and traffic to aid in understanding their details and dynamics.
