feat(bdtopo): restrict access to pedestrian ways according to bdtopo

Coincidence, in my daily watchfulness, I found yesterday https://www.mdpi.com/2220-9964/12/7/288 ( A Novel Method for Extracting and Analyzing the Geometry Properties of the Shortest Pedestrian Paths Focusing on Open Geospatial Data) ;

"For a long time, calculating the shortest (or fastest) path between locations A and B has been the center of pedestrian navigation systems’ attention. Nonetheless, “alternative routing” suggests that distance (or travel time) is not the only factor affecting the pedestrian’s route choices [1,2]. Other preferences, such as accessibility, convenience, comfort, etc., could be involved in such decisions [3]. The geometry properties of the shortest paths, including route curviness, the number of turns and intersections along roads, road gradients, sidewalk conditions (surface type, width, texture, etc.), and so on, might influence the route choice decision of particular types of pedestrians [4,5]. This is especially the case for people with limited mobility, like wheelchair users and older adults, experiencing major difficulties getting around urban environments."
