<p>Analyzes a roundabout and sets maneuver information. </p>
<p>Exit from a roundabout requires a somewhat complex analysis of the ways involved in order to: </p>
<ul>
<li>
Calculate effective bearing change (between entry and exit) and store it in<div class="fragment"><div class="line">cmd->roundabout_delta </div>
</div><!-- fragment --> </li>
<li>
Set<div class="fragment"><div class="line">cmd->maneuver->type </div>
</div><!-- fragment --> to<div class="fragment"><div class="line">nav_roundabout_{r|l}{1..8} </div>
</div><!-- fragment --> , based on bearing change </li>
<li>
Set<div class="fragment"><div class="line">cmd->length </div>
</div><!-- fragment --> </li>
</ul>
<p>Bearing change must be as close as possible to how drivers would perceive it. Builds prior to r2017 used the difference between the last way before and the first way after the roundabout, which tends to overestimate the angle when the ways leading towards and/or away from the roundabout split into separate carriageways in a Y-shape. This is referred to as</p>
<div class="fragment"><div class="line">delta1 </div>
</div><!-- fragment --><p> here.</p>
<p>In r2017 a different approach was introduced, which essentially distorts the roads so they enter and leave the roundabout at a 90 degree angle. (To make calculations simpler, tangents of the roundabout at the entry and exit points are used, with one of them reversed in direction, instead of the approach roads.) However, this approach tends to underestimate the angle when the distance between approach roads is large. This is referred to as</p>
<div class="fragment"><div class="line">delta2 </div>
</div><!-- fragment --><p> here.</p>
<p>Combining</p>
<div class="fragment"><div class="line">delta1 </div>
</div><!-- fragment --><p> and</p>
<div class="fragment"><div class="line">delta2 </div>
</div><!-- fragment --><p> , calculating error estimates for each and using a weighted average between the two delta estimates gives better results in many cases but fails for certain road layouts - namely, when corresponding approach roads are connected by more than one roundabout segment, or when additional ways connect to an approach road. These cases break error calculation and thus weight distribution.</p>
<p>Project HighFive introduces a new approach, which compares bearings of ways leading towards and away from the roundabout not immediately at entry and exit but at a certain distance from the roundabout, which is roughly proportional to the circumference of the roundabout. Circumference is estimated using the arithmetic mean value of</p>
<div class="fragment"><div class="line">delta1 </div>
</div><!-- fragment --><p> and </p>
<div class="fragment"><div class="line">delta2 </div>
</div><!-- fragment --><p> . This approach has produced the best results in tests. In code it is referred to as</p>
<div class="fragment"><div class="line">delta3 </div>

<p>Set of simplified distance values that are easy to be pronounced. Used for the 'vocabulary_distances' configuration. </p>
<p>This method of calculating the number of elements in an array (#define SIZE_OF_ARRAY_DISTANCES, below) will work for most modern processors. It may cause problems on a few obscure processors, none of which are likely candidates for navit anyway.</p>
<p>It works like so: Modern processors simply stuff the elements of an int array into memory one after the other, with no gaps. Some older processors might not do so, due to memory alignment issues. This method does not take such gaps into account. For more discussion, see <a href="https://github.com/navit-gps/navit/pull/373">https://github.com/navit-gps/navit/pull/373</a></p>
<p>So if you are on an oddball processor and start getting really odd values for distances, this might be the reason. Good luck! </p>
