Most traffic lights close together?
« on: September 20, 2020, 06:43:51 PM »

(Not counting places like downtown NY where there's one every block)
Where have you seen the most signals one after another? I would think they'd be in commercial areas but they could also be in a closely spaced interchange. This stretch of road near my house has six signals, the furthest apart being 800 feet.

The one place I know of that has too many lights close together is Bay City in Matagorda County in Texas.

This 1.4 mile section of TX 35 has 9 traffic lights:

Meanwhile, going south to north, this section of TX 60 has 10 within 2.1 miles:

If we're talking super close together, the best I can do for my area is three in 800 feet .

If we want to get creative and talk about how many signals you can see from one vantage point, from here you can see the next nine separate signalized intersections. Similarly, from here you can see the next six signalized intersections. I'm only including those last two examples because from those points the intersections look super close together (especially at night), even though in practice they aren't actually all that close to one another. It's all in the perception  :spin:

EDIT: Fixed South Portland dead link

The best I could think of near me, mostly in commercial areas but also near interchanges* are:

3 in 0.3 mile (0.48 km) in Saco ME*,
5 in ˝ mile (0.8 km), in South Portland ME*,
5 in ˝ mile (0.8 km), in Portsmouth NH,
5 in 0.4 mile (0.64 km) in Nashua NH*, and
6 in 0.8 mile (1.3 km) in Nashua NH.


This section of NY 404 has 15 traffic lights in 4.5 miles, four of which are visible here.

A bit off-topic, but red balls for the FYA signals? Thought that was a no-no per MUTCD...

Downtown any large city, first of all.

If we're looking for densely-packed threesomes, here is a threesome in 0.2 mile:

Hmmm. Could be. These are both newer signals and both have used the red balls instead of red arrows ever since they were replaced/installed, but I'll have to defer on if that's legal or not.

I once counted all the traffic signals on Mass Ave/MA 2A in Cambridge. 42 in 4.5 miles. That feels like a lot.

US 1 from the Beltway through Old Town Alexandria has one signal per block -- 15 in total over 1.75 miles. The city has typically done a good job with timing to prevent major traffic jams.

With that said, many urban cores across the country have stretches of road with a traffic signal at each city block.

I'm talking not in a downtown or urban core. Commercial areas work, as well as highway interchange lights and environs.
Here's a good example; this stretch of Irvine Center Dr/Moulton Pkwy in Orange County, CA, has 18 signals over 3.5 miles, resulting roughly in one signalized intersection every 1000 feet.

Another example closer to me: Bloomington's Market St has 10 over 1.7 miles, or a signal every 900 feet.

Downtown Bay City, MI has one on every block downtown along Washington Street.

What is it with Bay City's having annoyingly close together traffic lights?

Correct, they are only permitted for right-facing flashing yellow arrows. The 2009 MUTCD eliminated the option of a circular red; "LEFT TURN SIGNAL" signs must be used with circular reds.

FYAs designed prior to a particular state's adoption of the 2009 MUTCD might use circular red indications, but they should use the "LEFT TURN SIGNAL" sign.

I feel like left-turn FYAs from a road without an opposing left turn should be able to use circular red indications, but only if the left turn is lagging, and there is no leading-pedestrian-interval.

6 traffic signals along a 1/2 mile stretch of VA-190 Great Bridge Blvd in Chesapeake, VA, two of them from ramps from US-17 and one from I-64. And no, they are not timed or synced together.
