13. Regions of Maryland:
Western Region -- (Garrett, Allegany, Washington Counties)
Mid-Western -- (Howard, Frederick, Carroll Counties)
Baltimore Metro – (Baltimore, Harford, Cecil Counties and Baltimore City)
Washington Metro -- (Montgomery, Prince George’s Counties)

15. Common Belief:
Pedestrians are most often at fault in pedestrian crashes, especially in fatal crashes.

16. Explanation of Culpability
A crash may include the following groups:
1 pedestrian, 1 driver
1 pedestrian, 2 or more drivers
2 or more pedestrians, 1 driver
2 or more pedestrians, 2 or more drivers
Culpability Responses include:
Yes, No, Unknown for both pedestrians and drivers allowing for 9 possible combination of responses
For Crashes involving 2 or more pedestrians or 2 or more drivers
If any of the pedestrians were at fault, then pedestrian at fault was coded as “Yes”
If any of the drivers were at fault, then driver at fault was coded as “Yes”

18. Do the type of clothes and where the pedestrian crosses the road matter?

20. What are the posted speeds on roads with the most fatal and serious injury pedestrian crashes?
What road types do most fatal and serious injury collisions occur?
What about roads with medians – do barriers make a difference?

25. Summary
Statewide the number of pedestrian-involved crashes has steadily increased since 2012; however, the percentage of crashes was remained constant.
The top 5 jurisdictions for pedestrian-involved crashes includes Baltimore City, Baltimore County, Montgomery County, Prince George’s County, and Anne Arundel County.
The top 5 jurisdictions for pedestrian-involved crashes with the greatest percent increase include Carroll, Frederick, Charles, Cecil and Dorchester counties.
Baltimore Metro Region had highest percentage of no/minor injury crashes and serious/fatal injury crashes followed by Washington Metro Region

26. Summary Culpability -- The pedestrians aren’t always at fault –
42.4% Drivers – could be as high as 47.6%
33.3% Pedestrian
3.8% Both
37.1% of pedestrians wearing dark clothing were involved in crashes not at an intersection during no daylight as compared to 19.1% of those wearing light clothing
Two-way not divided road divisions account for the majority of pedestrian-involved crashes.
Over one-half of the serious/fatal Injury crashes occurred on roadways with posted speeds between 30 and 45 mph.
There was an increase in serious/fatal Injury crashes on state roads (34.4% vs 18.0%) and interstates (2.5% vs <1%) as compared to no/minor injury crashes .
