State DoT's Got My Memos

Seems like my blog has been having an impact on some state highway departments based on some of the innovating new road traffic signal indications I have been seeing lately. For example I that Diverging Clear has been one of the more common "non-standard" highway signals for a while now, but in New Jersey I found an example of Approach Diverging!


And if that doesn't get your cab signals flipping, while in Maryland I caught an example of another popular new highway signal indication, the flashing diverging arrow, which I assume is either an alternative to R/Y→ Diverging Approach or perhaps some kind of Slow Approach 🤔

This is a somewhat new development after the appearance of flashing Red arrows which is some kind of Diverging Restricted Proceed 🤷.  Anyway, who knows what they'll think of next? Perhaps something with flashing green. 😏

  1. The RBMN installed a recycled pair of Wigwag signals at Pittston to protect a new crossing on the Scranton Branch wye, they look like Western Railroad Supply Company Model 5 Autoflags.

  2. Virtual-headed signals are alive and well, after all, I guess. I don't think flashing green is coming to America anytime soon, though, as the federal MUTCD bans it outright. On the other hand, some states do use locally-modifed MUTCDs, so it's unlikely, but not impossible
