Transportation Data

We gather and analyze transportation data to better understand the nature of travel across our area, informing planning projects and helping us identify locations and topics requiring further study. This work includes our annual vehicle count program, walking and bicycling count program, and local crash data analysis.

Traffic Counts

We regularly collect and analyze data on vehicle travel within Dutchess County. This data is used to measure system performance, assist with road planning, and prioritize project funding. Other government agencies and private businesses also use the data for project planning.

We began our annual traffic monitoring program in 1999. The program is conducted by a contractor and focuses on county and local roads. Over 800 roadway segments are included in the program. Approximately 150-200 traffic counts are conducted annually, so most road segments are counted every few years. Most counts includes volume, speed, and vehicle classification (vehicle type) data, consistent with NYSDOT requirements. We also receive data from NYSDOT for State highways.

To improve public access to our traffic counts, we have an online mapping application - Traffic Data - that shows current and historical vehicle volumes on our road network. You can search counts by municipality, year, road name, or road class. Besides volumes, Traffic Data provides speeds and heavy vehicle information, and a range of tools to analyze, chart, and export data. The application also allows you to fully customize how data is displayed and to export maps as needed. 

Additional count data is available on NYSDOT's Traffic Data Viewer.

Pedestrian & Bicycle Counts

"What gets counted counts." We have very little data about how many people are walking and bicycling, and where. To address this, we collect bicycle and pedestrian counts across the county each September. The counts follow the methodology developed by the National Bicycle and Pedestrian Documentation Project and are used for several purposes:

  • To provide data that can be tracked over time to determine trends--e.g. how many more people are walking or bicycling after a project is completed compared to before; how many women are bicycling compared to men; how many bicyclists wear helmets, etc.

  • To determine crash rates and ‘hot spots’ for safety improvements. We have crash data, but need exposure data. If we know how many people are walking or bicycling in various locations, we can create crash rates (crashes per pedestrian or bicyclist volume) to better compare high-crash areas.

  • To prioritize locations for improvements, based on where the most people are walking and bicycling.

  • To draw attention to the needs of pedestrians and bicyclists—to show that there are people walking and bicycling, and the need for adequate facilities, safety, and support.

In addition, the data is available to the public and municipalities for grant applications and planning projects.

Locations are counted for two hours on a weekday (Tuesday, Wednesday, or Thursday) from 4-6 pm, and on a Saturday from 12-2 pm. Counts are done at ‘screenlines’ (along a street or trail) and at intersections. At screenlines, the counter tallies each person that crosses in front of them on the street or trail. At intersections, the counter tallies every time a person crosses the street or rides through the intersection.

The counts are conducted by volunteers from the our Bicycle-Pedestrian Advisory Committee (BPAC) and other groups, but additional volunteers are always needed! Volunteers benefit from seeing their community from a different perspective, participating in research that will be used by the County, and thinking about walking and bicycling as forms of transportation that deserve good planning. We provide training and count forms for volunteers.

Crash Data

New York State has a database of vehicle crashes collected from two sources: 1) Traffic and Criminal Software (TraCS), which many police agencies have installed in their patrol cars, and 2) NYSDMV crash report forms (Form MV-104). It was developed by the New York State Department of Transportation (NYSDOT), NYSDMV, and the NYS Office of Cyber Security and Critical Infrastructure Coordination (CSCIC).

The database allows us to search for crash data based on location, date, or other characteristics, and to summarize the data in various report formats. Currently, access to the data is restricted to State agencies, Metropolitan Planning Organizations, and relevant County agencies. We can provide local crash data on a case-by-case basis. To request crash data, please call or email us. When requesting crash data, please specify the following:

  1. Location (intersection or road segment)
  2. Date range
  3. Any specific crash types of interest (e.g. pedestrian only)
