    Sometimes, when I use "Follow Roads", instead of the route following a road, it plots a line to the next point, and then plots a line back to the LAST point by the most direct route (not following a road).

    I've noticed this behavior particularly when I'm plotting a route that passes nearby points earlier in the ride.

    Is this a known problem? I couldn't find a mention of this in the help, FAQ or forums.

    This appears to be a regression as it didn't happen before, I have noticed it myself a few times. I don't tend to use it as much, since I tend to upload GPX track logs which is much easier.

    Any Map My Ride staff/tech support people want to chime in on this?

     I too am having this problem to the extent that I was not able to finish a 60 mile route, very frustrating.  Would like to hear from Map My Ride on this issue.

    Hi Folks-

     Our dataset for this feature comes from a 3rd party webservice, and I suspect that the degredation is probably on their end, as our code for this hasn't changed since we first released it.  When I test the "follow roads" feature now, it appears to work fine, however I am obviously limited to testing a small set of geographical areas.

     For users experiencing problems, can you please reply in this discussion with more details, i.e. the exact geographical location where you see problems, and the exact symptom of the problem.  For example, is the error a performance degreation, or are you simply unable to plot?

    This thread caused me to audit our code, and I was able to find places to improve the performance.  I just released a (hopefully) improved version.  Can y'all tell a difference?

     Please let me know if you do see an improvement, and still do report the details I asked about above if you do run into issues.

    thanks,

    jeff

    I have experienced a similar problem -- I clicked to extend a route while Follow Roads was turned on and it drew a big circuitous route through other roads to a nearby point on the same road. I never was able to get it to go straight all the way down the road. It was almost as though the map plotter was describing a detour around an obstacle -- but the obstacle appeared to be the lettering on the map! I can confirm the road was open all the way through. This was on Howard Chapel Rd in Laytonsville (Montgomery County), Maryland, between Jennings Chapel Rd and Damascus Rd.

    May be unrelated - but any of my maps over 50 miles have been locking up and I cannot print or pull them up... ?? maps under 50 miles work fine?

    Seems like the place to put this.  In my initial attempt to use this feature I found that it seems to create an infinite number of points along a road instead of just points where you click to put them.  This in turn makes editing the points a near impossibility.  The little + cursor seems to follow along the road and can get to be a real nuisance but the problems with editing are really cumbersome.  I'm going to try creating a route not following the roads and then see if changing to that when it's finished will work.

    fkelly:

     I don't think that will work.  Follow roads on-or-off only matters when you click a point.   When you click the next point, if "follow roads" is off you get a straight line; if it's on you get a segment that follows roads from. the last point you clicked to the point you just clicked.

    Just my experience - if anyone has better information, please respond.

    Another piece of experience:  when using "follow roads" never click on intersections - always click on a point on the road you want to be on away from any other road.  If you click on an intersection you can get really "weird behavior" - like three turns at that intersection.

    I am having the same problem described by rmikkelsen on Aug 3 2007. On previous routes all seemed to work properly.  On the current route, the first three points seem to map to the road as i would expect, but the route to the fourth point is a circuitous path that ultimately leads to the fourth point I specified.  If you want specific locations I will provide them.

    Having read the comments in related threads, the problem I am experiencing (circuitous routings in follow roads mode) is possibly explained by the system applying one-way street rules where there is not a one-way street. 

     To mmf:  what about an option to establish routes with "follow roads" but without respecting one-way rules?  This feature would also help runners who can legitimately move opposite traffic on a one-way street.

    I have found the same problem, mainly at one-way roads. If you are using 'follow road' you can stop using it to take yourself down the road you want and then click back on follow roads and continue the map. Laughing

    Watch out for those interstate overpasses especially if they have an on off ramp. It might just take you to the next town and back.

    In creating a route on Bainbridge Island, WA I have experienced two problems with Follow Roads feature.  First is plotting a point at an intersection and then another point down the new road the program makes an incorrect note; e.g., "Turn right" when the actual plots made a left turn.  The second error is the circular route created at the intersection and automatic routing to another plot point that I have not selected.

    The software does not seem to recognize all roads equally.  Some portions of roads are represented visually, but no real  geometric coordinates are assigned to them.  When the program is determining the path while using 'follow roads,' these portions of road are essentially nonexistent, so it uses roads it can "see"  to create the next shortest route.  If the point to which you want the line drawn is not on a gap, the path will be drawn to it.  If it happens to lie on a gap, the path may be drawn to some nearby recognizable point or may not be drawn at all.  A good example of this can be seen on Beach Dr just below the Montgomery and Washington, DC border.  I believe the problem exists in Map My Ride's 3rd party mapping software.  It looks like the're using Google's maps.

    jaybros06 - never plot a point at an intersection - this is a nobrainer.  It you click on the intersection it can't tell if you're to the right, left,  past, or just before.  The exact intersection does not exit.  It's an abstraction.  So if you click at the intersection - just a half of a millimeter too far and then you intend to go left, it will make a U turn and turn right.  There is no other way for the system to interpret your clicks.

    NEVER CLICK ON AN INTERSECTION

    Did I say that already?  Ah, yes, see several previous posts.

    Click past the intersection on the road you want to turn into.

    When I am following roads, after turning around especially, I end up with a triangle.  I undo click by click, but no matter how much I back up I go off road to form a triangle.   I thus have to abandon the entire route and start over.

     See screenshot.

     

    This problem is so vexing that I am going to abandon MMR until it becomes a workable site.  I am wasting way too much time struggling with it.

    Ritterview  -   I find that that extra line disapears on its own if you just ignore it, or change the zoom level.

    This site is very frustrating, but it has so much promise that I keep comping back, especially for routes with many turns where I don't feel like reading and typing out all the turns and road names.

    The problem I've run into is the "follow roads" feature is still fairly highway-centric.  I want to parallel a highway on surface streets, the nominated bike route, but if I do it too far it takes the next big intersection and puts me on the damned highway.

    Also what would be useful would be selecting a box of waypoints for deletion.  Like a "delete section?" and then click on end point to work from and then be able to click "reconnect to route" near the end.

    I mention this because when I tried to change this 5 mile jump onto the highway there were about 5 bazillion points and it'd often grab one point over and over even when I was trying to grab the next one and it'd be floating about 2 inches to the right of the pointer.

    There are lots of good options on MMR, but definitely some bugs as well.

    RevJ.....  - "follow roads" feature is NOT fairly highway-centric  - it is absolutely highway-centric.  The algorith will find the fastest way to drive to the next point you click on.

    If you have a long section that got routed wrong, do not try to fix it by moving points; just click on "Undo" in the right hand toolbar and the problem section disappears. Then continue with a shorter segment.  This method works real nice.  Never click another point until you're sure the one you just clicked was routed to the way you want.  You can "undo" your last click, maybe two;  but you can't undo too many.

    This does NOT work the way google maps does where you get a route from point A to point B and then drag a point on the route to modify the route, in effect adding intermediate "via" points.  BTW - "bikely" does not have an undo like MMF's - a big negative in trying to use bikely.

    I'm plotting routes in a suburban neighborhood in the 93111 & 93117 zip codes.  It frequently plots wierd circuitous routes way off my intended route when I have it set to follow roads.  The only way I've found around it is to plot very small segments at a time, which defeats the whole purpose.  A real fix would be very much appreciated!
