I lug around about 6/7 bags of video equipment around from time to time for interviews I do. I could never manage it on the subway. It would otherwise be awesome to have less cars on the roads.
Pedestrian zones in German cities habe exceptions for transportation to or from locations inside them. Otherwise, stores in these areas couldn't get their wares etc. This just prevents regular car traffic and creates a safe space for walking. I don't know if the concept can scale tonan area the size of Manhattan. Just the necessary level of traffic would probably add up to to a lot of vehicles entering and leaving.
I would assume that the solution would be to ban traffic on most steets, but leave a coarse grid of open roads for passing traffic. This should still cut down on commuter car traffic on these.
The assumption that cars are the only publicly available cargo carriers would also be ridiculous if cars weren’t so abundant that all other solutions are floored. There’s everything from cargo bicycles to autonomous delivery vehicles that could fill this role.
Well, let's get back to first priniples. You need to be able to transport goods, that is, put them on wheels. Beyond a certain mass, you also need some kind of drive train to move it. Muscles can't produce enough force. And you need the flexibility to reach any address. These are fundamental preconditions without which large cities cannot exist. You need all of this for construction, maintainance and providing basic supplies for people living there and removing their waste. These requirements lead to a system of streets and cars/trucks of some sort.
Modern society uses the same system for individual transportation, which makes it inefficient in densely populated areas. Banning individual car traffic works in cities works because alternatives can be more efficient and they are practical because of the short distances involved.
Autonomous delivery vehicles in a pedestrian-filled area sounds like sci-fi given the current state of technology.
The amount of gear required for even a small production can be significant. I also do sound for a wedding DJ, and the rig that we bring to any event even if they have their own PA requires multiple trips with a large folding cart to bring from the vehicle to where it's going. We currently handle this by finding the closest place possible to pull up, throw our hazards on, get all the stuff inside, and then go find parking. Requiring another mode of transportation to and from the venue would add a bunch of time and difficulty, no matter how convenient it is.
This isn't a hypothetical; we did a gig in Atlantic City last December that was at the end of a long pier into the ocean, and the closest we could get was a no-parking zone on the other side of the board walk (the venue actually told us this was SOP). After unloading we put the cars in a garage a few blocks down (when you're using muscle power to move hundreds of pounds of gear, you get as close as possible, it's a safety concern). Not only did it take hours in freezing temperatures, but we had to bring an extra person with us to stay with the cars to make sure they didn't get tickets. It sucked. Hard.
It would make a ton of sense for park-and-ride like garages to have rental stations for cargo bikes or small electric delivery platforms (more like golf cart than car, e.g. Gator 6x6 though electric would be nicer). That way someone coming in would have a last mile solution that wouldn't present a huge danger to pedestrians. Or every few roads could be set to allow limited vehicle access for deliveries in normal hours and all roads allow nighttime deliveries. This wouldn't be a substantial burden while providing all the benefits of a carless space.
This is certainly a nice idea. But this is only usable for transporting smaller goods in small or medium amounts. This would not suffice to stock a busy grocery store, for example.
Isn't delivery traffic in German pedestrian zones mostly limited to certain hours? I recall seeing trucks in the early morning, but almost never during the day. Not sure if that was due to regulation or because that's when most deliveries naturally happen.
