StreetTraffic: a library for traffic flow data collection and analysis

This extended abstract introduces StreetTraffic, an open-sourced server library that collects and analyzes traffic flow data. By utilizing REST APIs provided by HERE.com, StreetTraffic allows the users to crawl traffic flow data of interested regions or routes. Then, the users could see the visualized traffic flow history of the crawled data, empowering them to understand the historical traffic pattern of their interested routes, which could be valuable to commuters or someone who wants to optimize a trip. The library is currently hosted at Github (https://github.com/streettraffic/streettraffic), along with its documentation and tutorials.
