I see Jim T beat me to the unmarked crosswalk issue.
Ref: Surprising Aspects of Maryland Pedestrian Laws:

I'm just not seeing any legal requirement not to use the unmarked crosswalk. We have a law how to cross with no pedestrian signal: § 21-202. Traffic lights with steady indication

And we have a law how to cross with a pedestrian signal: § 21-203. Pedestrian control signals

I don't see where you have to do one over the other.

Point #2:
"In all counties state roads account for the majority of pedestrian fatalities"

"The conclusions from this study were as follows:

• The detection distances to continental and bar pairs are statistically similar and are statistically longer than those for transverse markings.

• For the existing midblock locations, continental markings were detected at about twice the distance upstream as transverse markings during daytime conditions. This increase in distance reflects 8 s of increased awareness of the crossing for a 30-mi/h operating speed.

• The results of the appearance ratings of the markings on a scale of A to F mirrored the findings from the detection distance evaluation. Participants preferred the continental and bar pair markings over the transverse markings.

• Participants gave the continental and bar pair markings similar ratings during both the daytime and nighttime. However, the transverse marking ratings differed based on the light level. The participants gave slightly better ratings (although still worse than continental or bar pair markings) for transverse markings during the nighttime as compared to the daytime. The lower ratings during daylight conditions might be due to sun glare or shadow issues mentioned by the participants."

In other words, the type of crosswalk markings used by SHA have the lowest rating.
