The wide availability of high resolution city maps has radically changed our life during the last years. In particular, the routing services offer the capability to plan a travel by taking into account different transportation modalities, e.g., by car, train, public transport, bike, foot. Actually these routing services are mainly oriented to the majority of end-users and does not take into account particular constraints. This paper introduces a novel framework to assist people with mobility impairments in point to point navigation. The proposed framework is based on the creation of a road graph with different levels of detail (LoD) that can be modified at run-time by users if an obstacle obstructs the pre-planned path. Sidewalks, crosswalks and dynamic obstacles are also considered during the planning due to their importance for the navigation of mobility-impaired users. The proposed framework is based on OpenStreetMap (OSM) to manage and model the road graph, OpenTripPlanner (OTP) to plan a dedicated path considering different constraints, and mobile platforms for real time navigation and obstacle detection.
