Level of Service. Chances are, unless you’re in a field related to transportation planning or engineering, or are a total geek, you probably have not heard of this term before. LOS, however, has come to define how we design and build or roadways. Almost by its structure, LOS favors cars over the function or safety of any other mode of transportation. So what would happen if we took the same approach for other modes, like walking? More from Urban Kchoze:
The point of a traffic engineer in most studies is to keep level of service as low as possible to avoid delays for drivers, helping them drive faster and have to wait less for other traffic. Now then, some of you may ask “well, what about pedestrians and cyclists? How is level of service measured for them?” Well, the answer to that is that the default method says: F#!% ’em.
So let’s suppose that we calculate a level of service for pedestrians based on the same basis as for vehicles. Pedestrians can stop and accelerate to regular walking speed almost instantaneously and so we don’t have to calculate delay caused by lower than desired speeds during acceleration and deceleration. So delay is limited essentially only to the wait time before they can go ahead and cross (supposing car drivers respect pedestrian priority).
…crosswalks with medians and stop signs should be preferred to traffic lights for areas with a focus on pedestrians. It also means that the habit of channeling all the traffic on a few wide arterials, forcing each intersection to have multiple turn lanes and many through lanes, is absolutely terrible for pedestrians. A street grid with densely packed streets would do a better job of responding to all users, as it would dilute traffic on many streets, all these streets could be narrow, with 3 or 4 lanes only (1 per direction plus a shared left-turn lane or 2 per direction). Ideally, I believe there should not be any width of pavement greater than 12 meters (40 feet) in a city, any pavement wider than that should be broken in two with a median wide enough to use as a pedestrian refuge.
