Service Road affects routing?

Postby AggieJM » Wed Feb 20, 2013 9:21 pm

I've noticed an odd routing behavior, but I'm not sure if I'm seeing the right cause.

If you're on the far north side of Dallas, TX (Frisco) and heading to a destination south of Dallas on I-35E, the fastest route is to take the Dallas North Tollway south to I-35E in downtown. At the end of the DNT, there is a ramp that you leave the DNT that puts you onto the I-35E service road, then a few feet later you take the ramp onto I-35E. Service road segment highlighted in this permalink:

Whenever I route through here, Waze will always suggest DNT to I-635 west, to I-35E south. But as I drive down the tollway and get within a few miles of I-635, the routing will update to skip I-635 and use DNT all the way into downtown.

Is this cause by the longer route opting to not use the Service Road, then as I get further down the DNT, the route is shorter and the Service Road becomes an option? Or is there something else that I should be looking for?

If we just change that one segment of the service road, will it negatively affect any other routing along that service road? I'll make the change and test the routing after the next update, just wanted to make sure it wouldn't break any routing that uses a longer portion of that service road that includes that one segment.

Wasn't my choice. All of the frontage roads to the major highways in the Dallas area are set as the 'Service Road' type. It's been that way since before I started editing. I just noted the problem it was causing on my trips through the area.

The frontage roads along that section of I-35 have been set to Primary, but the same issue still exists. Waze will not route from the Dallas North Tollway onto I-35 on a long route since it appears that the Primary street is still being pruned until you get closer to that location.

Any other suggestions on how to resolve this issue?

The two concerns I had with swapping that to ramp:

1) Will it affect routing in that local area where you are using the segments of the frontage road before and after the piece updated to ramp?

2) Keeping other editors from "fixing" that segment to make it line up with the other segments of the frontage.

I can make the change if neither of these are a problem.

I changed that segment to a ramp. The ramp coming from the DNT and the ramp going to I-35E S have different names, so I don't think this will be an issue. I'll give it a couple of days to update, then I'll check the routing through the client for the trip that usually gives me issues.

If it all looks good, I'll get a Level 5 to lock that segment.

O Rly? The thread. That route wouldn't work if that were the case.

I don't know, but think that it is a very plausible theory. I don't have much experience with the routing properties of service roads, but have always been told that they are similar to street segments. I would be very interested to know if the long distance routing changed if that segment were changed to ramp type.

Would not ramp type also prevent this from happening? The segment is between two ramp segments and it would seem to me to be much less likely to be "corrected" as a ramp segment than as the only minor highway segment within a half mile of that location. Either way, I would be interested to confirm that the long distance routing changes with a change to the road type here.
