Estimating Driver Response Rates to Variable Message Signage at Seattle-Tacoma International Airport
Blog Article
We apply Bayesian Linear Regression Cooler Bag to estimate the response rate of drivers to variable message signs at Seattle-Tacoma International Airport, or SEA.Our approach uses vehicle speed and flow data measured at the entrances of the arrival and departure-ways of the airport terminal, and sign message data.Depending on the time of day, we estimate that between 5.5 and 9.1% of drivers divert from departures to arrivals when the sign reads "departures full, use arrivals", and conversely, between 1.
9 and 4.2% of drivers divert from arrivals to departures.Though we lack counterfactual data (i.e., what would have happened had the diversionary treatment not been active), adopting a causal model that encodes time dependency with HISENSE PureFlat RF540N4WF1 Fridge Freezer - Black Steel prior distributions rate can yield a measurable effect.
