Institute of Transportation Studies Friday Seminar: Large-Network Travel Time Distribution Estimation for Ambulances

Ambulance in Georgetown. BW.

It's almost Friday, so it's almost time for the Friday Transportation Seminar. Remember that this semester the seminars and Cookie Hour are in 290 Hearst Memorial Mining Buidling. We also encourage you to follow along (and participate) with the Twitter hashtag #itsberksem

This week's Friday Seminar features Dawn Woodward from Cornell presenting, "Large-Network Travel Time Distribution Estimation for Ambulances."

We present methods to predict the time required for an ambulance to drive to the scene of an emergency. This forecast is critical for deciding how many ambulances should be deployed at a given time, where they should be stationed, and which ambulance should be dispatched to an emergency. Specifically, we predict the distribution of lights-and-sirens ambulance driving time on an arbitrary route in a road network, using automatic vehicle location data and trip information from previous ambulance trips. We train a statistical model using a computationally efficient procedure; challenges include the large size of the network and the lack of trips in the data that follow the route of interest. We demonstrate the operational impact of our methods using data from Toronto Emergency Medical Services, and discuss ongoing efforts to incorporate our methods into a software package used by ambulance services.

The Friday Seminar takes place on September 5, 2014 from 4:00-5:00 PM in 290 Hearst Memorial Mining BuildingCookie Hour immediately precedes it at 3:30 PM in the same location. (Note: Cookie Hour is not in the library!) There will be a no-host Happy Hour at LaVal's at 5:00 PM.
