Safe Communities - Transportation Safety Plan

Car accident

Clackamas County is a diverse 1,879 square mile region with over 3,000 miles of roads connecting a mix of urban and rural communities. Given the large rural area, mix of road types and conditions plus the many various agencies involved in the safety of the public on these roads, it has been difficult to determine how safe the roads were and what could be done to make them safer for everyone. Studies have shown that from 2005 to 2009, 160 people lost their lives, more than 900 were seriously injured and an average of 3,917 crashes occurred each year on Clackamas roads — the third highest in the State of Oregon. It was decided that something had to be done.

In 2005, the Clackamas County Safe Communities Program (CCSCP) was formed to coordinate and collaborate with other regional agencies to promote safety and education. These partnerships opened communications between agencies and the public about safer driving. Given the success of the CCSCP it was decided to take road safety to the next step. In cooperation with the Oregon Department of Transportation, CCSCP initiated the development of a Transportation Safety Action Plan (TSAP). After extensive research into the conditions of the transportation system, the history of accidents and the resources available/required to build the programs required to improve safety, a plan was adopted by Clackamas County in 2012 with the goal to have the initial phases implemented in 2013/2014. The plan would be reviewed and updated on an ongoing basis to create the safest transportation system possible.

With the collaboration of many regional agencies the initial phase planned two technology tools to assist in the communication and development of the TSAP:

  • A Clackamas County sponsored web site that would be the communications "hub" for the various agencies and the public — essentially a one-stop shopping location for disseminating the many types of information available.
  • A sophisticated analytical tool to collate available data from numerous sources and map the incidents based on various criteria and provide a source of data compilation for other types of analysis. This application would be the basis for determining future actions and the impact of those actions.

The Safe Communities web site was designed to be a landing page for all services, agencies, users and information related to enhancing overall safety of Clackamas County transportation. This allows a single place for communications, a calendar, event updates, email notifications, educational materials, news releases, etc. It contains a mix of interagency information in one searchable site. The site allows for access by the public and registered members. Members have additional access to forums, email subscriptions, event calendar updates, various reports and additional information. Clackamas County designed and maintains the site as a non-charge service for the other agencies and partners. The site is Continually updated with new information, events and reports.

The Safe Communities Analysis Application is an online tool that allows users to spatially and tabularlly query crash data from various sources. Users have the option to query using a dynamic query panel, location query panel or selection tools provided within the map toolbar. The dynamic query panel contains a list of predefined fields that allow the user to combine several query fields into a single statement. The user also has the ability to request additional display fields before submitting the query. The location query panel provides the ability to either zoom to an intersection or jurisdiction. The jurisdiction query contains a dropdown list with predefined locations to assist the user. Once the user has identified their geographic location they will have the option to spatially interrogate the data with the provided map tools. These tools include: highlight feature by point/area, select crash by point/icon, and buffer graphics. All successful query results involving crash related data will display on the map and a listing of the returned crash information will be displayed below the map within a table format.

Next Steps

There are already designs in development to add additional datasets to the Analysis Application as well as new formats for reporting/extracting the results. This will provide even more ability to determine the areas of the County that need the most attention and the results of previous actions to resolve problem areas. As the next phase is developed, additional ways to search and organize the results will be made available. The website will continue to be supported and expanded with new information and capabilities as resources are made available.

Services & Benefits

The overall Safe Communities program and Transportation Safety Action Plan has been a major success from the perspective of improved communications, cooperation and education. With the continued commitment of Clackamas County and our partner agencies — and based on results obtained from the new TSAP Mapping Application — it is expected there will be a definite reduction in the number and severity of traffic accidents. From the perspective of the technology utilized to support Safe Communities and the data analysis, there are other important benefits realized as well. Ultimately, its effectiveness will be measured by the number of lives saved.

Safe Communities Website:

  • One stop location for regional agencies and citizens to search/use traffic related information
  • Shared calendar of events and educational opportunities
  • True inter-agency cooperation and participation
  • Collaboration on resources for new research initiatives and educational programs
  • Collaboration on information, education and communication between a dozen agencies
  • Several other jurisdictions are interested in creating similar programs/sites
  • Savings realized by reduction in replicated services, common marketing platform

TSAP Analytical and Mapping Application:

  • Powerful, flexible tool for mapping accidents with several formats for searches, exports and reports.
  • Multi-dimensional searches on multiple types of events, criteria, locations etc
  • Refinement of searches by event details, demographics, time, alcohol and other factors
  • Ability to export data in multiple formats to other utilities
  • Large array of datasets available for analysis and mapping
  • Application allows tracking of events both before and after remediation to determine level of impact and help in the assessment of future actions.
  • Provides base for future development of analytical tools to expand TSAP goals


The application portion of Safe Communities utilizes the new Mapping Application Development toolkit that TS developed to help in the rapid development and deployment of GIS based applications. (See the Mapping Initiative that is part of this survey).

  • HTML 5 and CSS3, Java
  • ESRI GIS for mapping services
  • Postgres Database
  • Current Datasets include (to be expanded)
    • Clackamas County Geospatial Database and layers
    • Clackamas County Sheriff’s Office
    • Oregon Department of Transportation crash database
    • Clackamas County Department of Communications (911) Crash Database
