They aren't anything ground breaking. Just a bit on integrating a little common sense with slowing vehicle speeds down in certain environments and better separating motorized and non-motorized traffic in others. Then in both cases, better integrating transportation infrastructure with land use policy.
So for example, FDOT now allows lane widths of 10.5' - 11' in certain situations. That's a great thing for slowing traffic down through certain built environments. COJ, should consider doing the same. Another example, would be embracing multi-modal connectivity in built environments, regardless of if the project is a roadway resurfacing job, maintenance or new capacity project. This means incorporating physically separated shared use path facilities with projects like the Fuller Warren Bridge expansion or the First Coast Expressway. Last, there's an issue of safety. A stripe of paint being the only thing separating bicyclists from 50mph traffic on a 6 - 8 lane highway or a 5' sidewalk with no shade trees aren't the most ideal solutions for those modes. Once auto/truck maximum speed limits are allowed to exceed a certain number, effort should be taken to physically separate these modes to the highest extent as possible.
Oh, and one more. Many of our urban core streets are much wider than they have to be. Some, like Park Street or Edgewood Avenue, would be prefect for lane diets to create space within the existing curb & gutter for other uses.
Beach Boulevard
Bad solution for bike lanes. Too much auto traffic, traveling at high speeds.Beach Boulevard
So despite bike lanes, the average person will ride on the narrow 5' sidewalk. However, this creates a dangerous condition for pedestrians. Oh, by the way, the bus stop in the image isn't ADA accessible either. It would suck to be confined to a wheel chair and having to use this stop.BetterSR 347 - Hauppauge (Long Island), NY
Better off (in the design stage) taking that extra 8' of dedicated bicycle lane and going with a shared use path for both bike and ped traffic.Pace Road - Lakeland, FL
Even in suburban situations, some communities have changed their local design standards to better separate bike traffic from facilities designed for significant auto traffic and speeds.
