    2.7 Location of Road Vehicle Crashes 

    2.7.1 on-roadway crash: An on-roadway crash is (1) a crash in which the initial point of contact between colliding units in the first harmful event is within a roadway or (2) a noncollision crash in which the road vehicle involved was partly or entirely on the roadway at the time of the first harmful event.

     

    2.7.2 off-roadway crash: An off-roadway crash is any road vehicle crash other than an on-roadway crash.

     

    2.7.3 at-intersection crash: An at-intersection crash is a traffic crash in which the first harmful event occurs within the limits of an intersection (See Figure 5).

     

    2.7.4 driveway access crash: A driveway access crash is a traffic crash in which the first harmful event occurs on a driveway access (See 2.5.9) or involves a road vehicle entering or leaving another roadway by way of a driveway access (See Figure 4). This requires at least one traffic unit (vehicle, pedalcyclist, or pedestrian) to be physically on the driveway access within the trafficway.

     

    Inclusions:

     

    • Crashes occurring on sidewalks within the driveway access

     

    Examples:

     

    1) A car turning into a private residence driveway striking a bicyclist riding on the sidewalk that crosses over the driveway access

     

    2.) A tractor trailer backing out of a business entrance onto the trafficway, while partially on the driveway access, is struck by a car on the roadway

     

    Exclusions:

     

    o Driveway access-related crashes (See 2.7.4.1)

     

    Examples:

     

    1.) A car on the roadway waiting to turn into a driveway is rear-ended by another motor vehicle

     

    2.) A truck in the process of turning out of a driveway, but is no longer on the driveway, strikes a motor vehicle (or non-motorist) on the roadway

     

    2.7.4.1 driveway access-related crash: A driveway access related-crash is a traffic crash that (1) occurs adjacent to a driveway, (2) is not a driveway access crash, and (3) results from an activity, behavior, or control related to the movement of traffic units onto or out of a driveway.

     

    Inclusions:

     

    • A traffic crash, other than a driveway access crash, which occurs at the connection of a driveway and a roadway and is related to the driveway access

     

    Examples:

     

    1.) A car on the roadway waiting to turn into a driveway is rear-ended by another motor vehicle

     

    2.) A truck in the process of turning out of a driveway, but is no longer on the driveway, strikes a motor vehicle (or non-motorist) on the roadway

    Exclusions:

     

    o Driveway access crash (See 2.7.4)

     

    2.7.5 intersection-related crash: An intersection-related crash is a traffic crash in which the first harmful event (1) occurs on an approach to or exit from an intersection and (2) results from an activity, behavior, or control related to the movement of traffic units through the intersection (See Figure 5).

    2.7.6 nonjunction crash:  A nonjunction crash is a road vehicle crash that is not an at-intersection crash, a driveway access crash, or an intersection-related crash.

     

    2.7.7 interchange crash:  An interchange crash is a traffic crash in which the first harmful event occurs within boundaries which include all ramps of auxiliary roadways and include each roadway entering or leaving the interchange to a point 30 meters (100 feet) beyond the gore or curb return at the outermost ramp connection. Interchange crashes may include at-intersection crashes, intersection-related crashes, driveway access crashes, or nonjunction crashes (See Figure 9).

     

     

     

    2.7.8 work zone crash: A work zone crash is a motor vehicle traffic crash in which the first harmful event occurs within the boundaries of a work zone or on an approach to or exit from a work zone, resulting from an activity, behavior, or control related to the movement of the traffic units through the work zone (See 2.5.24).

     

    Inclusions:

     

    • Collision and noncollision crashes occurring within the signs or markings indicating a work zone

     

    • Collision and noncollision crashes occurring on approach to, exiting from, or adjacent to work zones that are related to the work zone, regardless of distance

    Examples:

    1.) An automobile on the roadway loses control within a work zone due to a shift or reduction in the travel lanes and crashes into another vehicle in the work zone

    2.) A van in an open travel lane strikes a highway worker in the work zone

    3.) A highway construction vehicle working on the edge of the roadway is struck by a motor vehicle in-transport in a construction work zone

    4.) A rear-end collision crash occurs before the signs or markings indicating a work zone caused by vehicles slowing or stopped on the roadway because of the work zone activity

    5.) A pickup truck in-transport loses control in an open travel lane within a work zone caused by a shift or reduction in the travel lanes and crashes into another vehicle down the road that had already exited the work zone

    6.) A truck tractor approaching an intersection strikes a pedestrian outside of the work zone. The crash is caused by a lack of visibility created by work zone equipment on the intersecting roadway

    7.) A sport utility vehicle loses control and overturns on a roadway within a work zone due to a severe lane shift without any collision event

    Exclusions:

     

    o Crashes involving working motor vehicles that do not involve a motor vehicle in-transport

     

    o A crash that occurs on the opposite side of a divided highway from the work zone, if the work zone is not signed on the crash side of the highway, and the crash is clearly unrelated to the work zone

     

    Examples:

     

    1.) Two motor vehicles performing work in a work zone collide

     

    2.) A highway maintenance truck strikes a highway worker. Both are within the closed portion of the work zone

     

    3.) A utility worker repairing the electrical lines over the trafficway falls from the bucket of a cherry picker without being struck by a motor vehicle in-transport

     

    2.7.9 entrance/exit ramp crash: An entrance/exit ramp crash is a traffic crash in which the first harmful event occurs on an entrance or exit ramp roadway and is not the result of an activity, behavior, or control related to the movement of traffic units through an intersection. This would include all areas between the gore and termination of the entrance/exit ramp.

     

    2.7.9.1 entrance/exit ramp-related crash:  An entrance/exit ramp-related crash is a traffic crash in which the first harmful event occurs off the entrance/exit ramp roadway, but is related to the use of or entry onto the ramp. If the first harmful event occurs in the intersection of a ramp and a surface roadway, then it would be classified under 2.7.3 – at-intersection crash.
