When there is one exit lane that comes from the left and one from the right, but the right one has right-of-way, is there there a name for such ramps merging into a road? There is so much confusion at such ramps because the yield signs often are awkwardly and unclearly placed. Ramp from left; ramp from the right; pedal to the metal; fight! fight! fight!

I don't even understand this much of your question. Exit lanes don't come from, they lead to.

Well, in the instance of which I'm thinking and have experienced, one exit ramps comes off I-95 from one direction and the other comes off I-95 from the other. The two exit ramps merge precariously. I was just wondering whether there is a term for two ramps merging into one area--I would think there would be such a term in the civil engineering lexicon. My term is: Danger!

I always call those types of configurations "Suicide Ramps". I usually see something more like an on ramp merging with an off ramp. What am I saying, I don't even have to deal with traffic lights anymore! Everyone here drives politely and rarely exceeds 35 MPH. It's a whole 'nother world...

one exit ramps comes off I-95 from one direction and the other comes off I-95 from the other. Uh--as in, one from the southbound lanes and one from the northbound lanes? The two exit ramps merge precariously. In a rest stop in the median, maybe? Sorry, I just can't visualize what you're talking about.

DubDub, maybe you could post a close-up mapquest of what you're talking about; I too am a little confused (which is the norm, of course, but).

here in NY(C) we call them 'Robert Moses' Ramps. RM didn't drive, and one of his 'innovative' money saving features was to use the same (short!) strip of roadway for 'accelerating' and 'de-acelerating'--so on many NY roadways, you come down an enterence ramp onto as little as 100 feet of roadway. as you are trying speed up, and merge into the right lane, traffic from the right lane is trying to merge into the same 300 foot strip and slow down!
in other places the overlap is on the service road or local city street-- you are coming off a highway/parkway, trying to merge into traffic, and traffic (planning to enter the same highway) is trying to merge into the same lane.
and some of robert moses merge lanes are as short as 80 feet! (yes, about 4 car lengths. the worst?
Cross Island parkway, (come down a incline, STOP Sign at bottom of ramp, traffic on cross island is coming round a turn, (so you can only see 'back' about 300 yards!) and you have 2 car lenghts to 'merge'. one of my least favorite enterences.
there are several 'entry ramps' like that on X-bronx expressway (i-95), Meadowbrook, Wantagh, and Southern (state) parkways as well. some have been 'improved' but some remain.
another 'innovative' space saving feature of highways RM designed are left hand exits and entryways.. How would you like to come round a left turning spiral ramp down to a highway that has traffic coming out of a right spiral, onto a left hand entryway? (it is about 200 yards long, so its not impossible short, but its no fun!--location? (south on Whitestone expressway, 3rd exit (highway split) for Grand Central Parkway --then take Grand central EAST (at that point, its really heading south, but it turn again in a few miles and resumes its easterly course. (this path takes your right past Shea Stadium)

I found the map, but the link is too long. What's that 'shorter link' url? Post it here and I'll take you to the map of the ramps in question. There has got to be an engineering term for such ramps. I liked consuelo's 'suicide ramp' term and of troy's 'RM' ramps. Those are terms that do apply to the place I'm thinking about.

'Entrance' ramps "merge" into a road and 'exit' ramps "peel off".
