Intersection Control Figure 13 and Figure 14 depict crashes by intersection control (where data is available) for all modes and for VRUs. For all modes, crashes occurred slightly more often at signalized intersections (53.4% of all crashes). The share of KSI crashes at signalized and unsignalized intersections is roughly the same. However, crashes at unsignalized intersections tended to result in slightly more severe outcomes.

The VRU-involved crashes show a different pattern from all mode crashes (see Figure 14 ). Despite a slightly smaller percentage of VRU crashes at signalized intersections (49.8%), a higher percentage of those crashes were KSI crashes. VRU crashes at signalized intersections are 1.3 times more likely to result in severe outcomes than those at unsignalized intersections.
