Emergency Vehicle Trip Analysis using GPS AVL Data: A Dynamic Program for Map Matching
نویسنده
چکیده
We outline a new dynamic programming approach for determining the most likely route taken by a vehicle given a set of GPS locations and times recorded by an AVL (automatic vehicle location) system. By using optimisation approaches, this map matching algorithm can solve a complex maximum likelihood problem that takes into account data such as the vehicle’s location, heading, and speed. The optimisation approach allows routes to be determined even when the GPS data points are widely spaced in time and/or distance. Preliminary results are reported using data collected from ambulances.

متن کاملTravel Time Estimation for Ambulances using Bayesian Data Augmentation
Estimates of ambulance travel times on road networks are critical for effective ambulance base placement and real-time ambulance dispatching. We introduce new methods for estimating the distribution of travel times on each road segment in a city, using Global Positioning System (GPS) data recorded during ambulance trips. Our preferred method uses a Bayesian model of the ambulance trips and GPS ...
