Traffic Accident Analysis

Summary Report of High-Crash Road Segments and Intersections in Tompkins County, N.Y., (revised 3/4/2013)

Prepared by the ITCTC
This year the Ithaca-Tompkins County Transportation Council (ITCTC) analyzed traffic accident data for the first time. The traffic accident data was downloaded for each municipality from the New York State Department of Transportation (NYSDOT)’s ALIS database (Accident Location Information System) for the years 2000 through 2010. This database utilizes all crashes reported to the Department of Motor Vehicles (DMV).

NOTE: The ALIS database only includes crash data for ‘public’ roads and intersections. Therefore this analysis does not include crash data for Cornell University and Ithaca College – which are ‘private’ roads.

National Household Travel Survey:

The National Household Travel Survey (NHTS) previously called the Nationwide Personal Transportation Survey (NPTS) serves as the nation's inventory of daily personal travel. It is the only authoritative source of national data on daily trips including purpose of the trip, means of transportation, how long the trip took, day of the week and month, number of people on the trip etc.

In 1995 and again in 2001, NYSDOT participated with the Federal Highway Administration as one of several add-on areas. NYSDOT purchased additional household samples to increase the coverage and reliability of the NPTS data for analysis of the travel patterns of residents within New York State.

1995 NPTS (conducted from May 1995 to July 1996, released February 1998. Oak Ridge National Laboratory)
