Here is a nice compendium from Plan Philly on dealing with urban street congestion. Although, the term congestion to most people implies high traffic volumes and low speeds, which you could argue are acceptable in cities. I will admit though that here in Philadelphia we need solutions to temporary delivery, loading and contractor parking. These legitimate business activities block bike lanes, sidewalks, and travel lanes because they often have no choice. I’ve done it myself. Pedestrians, bicyclists, and drivers can curse at each other all day – but the same person can be all three at various times, so we are cursing at ourselves. We need solutions and compromises that work for everyone. There are some good, pretty obvious ideas in this article that really shouldn’t encounter bureaucratic or political resistance: larger loading zones, metering loading zones, letting people reserve them in advance, congestion pricing, and off-hours delivery, to name a few.
