Junction penalties: rewording; format list with bullets
===Junction penalties===
Currently Waze applies a 5 five-second time penalty for passing when calculating a route that passes through each a junction. While not an unreasonable approach to dealing with intersections, it has generated some flawed routing and is being reviewed. One major issue arises in long highways which may be made up of hundreds of segments connected together. This may add a 5 minute penalty to a trip, even though the intersections are not real.
One major issue arises in long highways which may be made up of hundreds of segments connected together, as this may add a penalty of as much as five minutes to a trip, even though the intersections are not real. This supports the arguments of those who aim to have a clean edit of maps where junctions are only used when necessary. In practice , we need to deal with the map as it stands. An automated tool to remove the junctions is needed as the manual work that is required is enormous.
The routing problem can be fixed in a variety of ways. One could not :* Not apply the penalty when there are no other existing roads meeting. at the junction;* Not apply the penalty when you are travelling on to cross a junction onto a road with the same name. ;* Not apply the penalty when the road you are travelling on is a higher class (eg e.g. highway versus street, primary street versus street) , where we can assume the higher class road has the right of way. Or just not ; or* Not apply the penalty at all when travelling on freeways, motorways and highways.
Even if a road is correctly connected with no unnecessary segments, the junction penalty can still give incorrect results. For example a busy highway may be correctly connected to the ramps along its length. A quiet country road running in parallel may not have all the minor connecting roads recorded - ; it looks like a straight section of road with no junctions. Waze may choose it the country road as the preferred route because of the lack of junctions.
