Falls or other events involving only bicyclists that might be documented in medical databases are not included. While past research indicates that bicycle-motor vehicle crashes represent approximately 20-30% of all injuries to bicyclists, it is clear that most of the serious and fatal pedestrian injuries do involve motor vehicles. Besides the standard data elements on the NC crash report form, the UNC Highway Safety Research Center staff used PBCAT (Pedestrian and Bicycle Crash Analysis Tool) software to add a specific crash type to each crash for which a report form was available. Crash typing is a methodology to better define the sequence of events and precipitating actions leading to a crash. An example of a bicycle-motor vehicle crash type is bicycle ride out at intersection. Coding of who was at fault was also added. Fault was derived by examining the investigating police officer's sketch and narrative, as well as his/her indication of the contributing circumstances and any subsequent charges. These data can be used to derive information about bicycle-motor vehicle crashes in NC. The user may select data in a variety of ways: • For the entire state • For the Piedmont, Coastal, and Mountain regions of the state • For an individual county or selected counties • For an individual city or selected cities   Please note that no crashes were reported during this time period for some of the NC towns and cities. Data like these are typically used to develop general descriptions of crashes. This process is sometimes referred to as the problem identification stage. For a detailed review of crashes in specific locations (e.g., corridors or certain intersections within a community), it will be necessary to obtain such information at the local level. Likewise, development of specific treatments or countermeasures normally takes place after discussions with knowledgeable local officials.
