No, at least not for I-405 &#x2F; I-5 near Seattle.<p>These roads, due to a complete lack of effective urban planning and development, are several times over capacity.<p>I like to think that this heuristic would be effective for such cases.<p>* Aim for a hard speed limit (maybe the actual speed limit).<p>* Actually obey the law of this state: Keep Right Except to Pass.<p>* ALWAYS allow merges (from either side) with higher priority.<p>Edit:<p>After reading the github link from one of the other posts I want to expand why I disagree and suggest always allowing merges.<p>It is to allow traffic to leave the freeway (merge right to exit) as well as to enter the freeway (merge left, mostly to enter at all, but also in case they&#x27;re going a long distance or need to get to special use lanes on the left).
