Other companies could do the same either way -- Econolite does with the ASC/3 line.

Now that I didn't know. I haven't been close enough to see the menu structure on the 2070s. I figured the Intelight's had Max Time and the Siemens' has SE-PAC. Never heard of D4! Enlighten me on this software!

I don't understand why some intersections had the controller in the existing Eagle cabinet swapped out, and others were disconnected and the field wiring was spliced over to a large 340 ITS cabinet. The ITS cabinet makes sense because its designed for 2070ATC controllers. Seems like it could be a pain trying to convert a cabinet that has non-NEMA spec connectors and I/O.

Michigan was slow to get into the NEMA market after the mechanical era ended. The EF140 and EPIC140 were designed for the Michigan market to be a menu driven equivalent to mechanical controllers and to allow for the unique specifications (flashing red, end-with-left cycle, single section right turn arrow, etc)

Well, first of all, I'm pretty sure Macomb Co was putting D4 software on those 2070s, but I could be wrong. I do know that Oakland Co. uses SCATS from Transcore, which also runs on 2070 controllers. D4 is the software designed by a company called 4th Dimension Traffic, which has basically no website, and is basically defunct now -- it was a garage software development operation by one guy, and was widely used in the city of San Francisco if I recall. He recently had some sort of major health issue, though, so his company is effectively done, and we're now picking up some of their customers to go with our software instead.

Just remember, just because a 2070 controller may be of a certain brand, does not mean that the same company's software is also running on it. Ohio DOT frequently buys Econolite 2070 controllers, but puts SEPAC on them!

Interesting!! Never heard of D4 before this is there a picture or something of the menu screens?

I know Oakland County uses SCATS. They still are using the FAST TRAC system too which was state of the art in its heyday...the 1990s!

Thats true you could put any local software on any 2070.. whoops! I'd love to learn even more about Macomb County's signal system. I know quite a bit... but I have much I still need to learn!
