Estimating External Travel Using Purchased Third-Party Data

Roadside origin and destination (O-D) surveys have historically been conducted by the Department or its consultants. These surveys require staff to stop all traffic on each surveyed road and therefore can be costly and bothersome to motorists. Furthermore, the Department prefers not to stop traffic on Interstate Routes (IR) for these surveys. Surveys were conducted at over 700 locations from 1995-1997 at a cost of around $7M for the purpose of travel demand model (TDM) estimation. Between 1997 and 2002, surveys were conducted at 10 cities to determine the need for bypasses or other transportation improvements. In 2008, surveys were conducted around Allen County to expand the TDM study area. In 2009, the Department studied the use of Automatic License Plate Recognition (ALPR) cameras to capture the through traffic on IR 75 through Allen County. However, the ALPR cameras are only able to collect the traffic that is traveling the entire IR through the study area as only 4 cameras are owned by the Department. Third-party OD datasets have recently become commercially available for transportation planning purposes. These datasets are produced from various types of data and can be purchased from Inrix, Airsage, American Transportation Research Institute (ATRI) and others. This research project will determine whether third-party datasets are able to replace roadside O-D surveys. Datasets will be obtained for the Lima-Allen County Regional Planning Commission (LACRPC) model area from at least three vendors and will be compared to the 2008 Cordon Survey and 2009 ALPR study for Allen County. Trip purposes will be imputed from the datasets as best as possible if they are not already commercially available. O-D matrices (both Internal-External (I-E) and External-External (E-E)), time of day (TOD) patterns and trip purposes will be compared. Resident vs. non-resident may also be compared.
