javascript - OpenStreetMap following road/street latlng

Question

I'm working on a webapp using OpenStreetMap and Leaftlet, this app will seems like an GPS app using your car position to navigate the map, In this case I need to obtain the next 100 to 200 meteres of the driving road, to retrieve additional information about the street.

Any ideas ?

E.g When car through the next 100 meters I will Suggest to take another way because there is a traffic jam there..

Thanks

有多种方法可以获取OSM 数据的小快照。但是“接下来的 100 到 200 米”在所有情况下都不够。绕路可能会更长。
