freight vehicles and urban design

Leave a reply

Next City has a roundup of ideas for more efficiently accommodating freight vehicles in dense cities.

  • Better, cheaper (or even free to the user) public transit, so there aren’t so many cars clogging up the streets trucks need to drive on
  • “logistics hotels” where goods from many sources can be mixed, matched, and put on smaller vehicles appropriate to city streets (this is kind of how a port works?)
  • “design infrastructure like intersections and bus lanes with interactions between freight activity and vulnerable road users, like children, in mind” (sounds good, if a bit non-specific
  • Design trucks so they just aren’t so dangerous
  • Better allocate curb space to get more deliveries out of fewer vehicles

I have a few more ideas.

  • Don’t forget some kind of temporary parking for contractors and delivery people serving urban customers. It doesn’t have to be free, but it should be reservable.
  • Don’t forget garbage trucks, unless we are going to think of a better way to deal with garbage or get rid of garbage entirely.
  • Alleys can work well for trash and deliveries, if they are designed with that purpose in mind. They can provide play space and just generally space for people to spread out the rest of the time (but NOT if they are just a bunch of garage entryways).
  • I still want my robot deliveries, both ground and air! In my city though, robots using the sidewalks for deliveries will need them to be in a better state of repair, and that won’t happen because sidewalks are technically the responsibility of homeowners, many of whom are poor and/or don’t even know the sidewalks are their responsibility. On the few streets with incompetently designed, unenforced, and unmaintained bike lanes, the robots’ wheels and gears will get all gummed up with the blood of children and old people who believed the mayor’s promises to build safe protected bike lanes like they have in Europe.
  • I’ve said it before and I’ll say it again. COPY DUTCH STREET DESIGN NOW!!! Just don’t let it go to their heads, the smug bastards…

August 2020 in Review

Goodbye summer, hello fall (or do you prefer to say autumn?) in this weird and consequential year.

Most frightening and/or depressing story:

  • We just had the 15-year anniversary of Hurricane Katrina, a major regional crisis that federal, state, and local governments failed to competently prepare for or respond to. People died, and decades later the recovery is incomplete. Coronavirus proves we learned nothing, as it is unfolding in a similar way on a much larger and longer scale. There are many potential crises ahead that we need to prepare for today, not least the inundation of major cities. I had a look at the Democratic and (absence of a) Republican platforms, and there is not enough substance in either when it comes to identifying and preparing for the risks ahead.

Most hopeful story:

  • Automatic stabilizers might be boring but they could have helped the economy in the coronavirus crisis. Congress, you failed us again but you can get this done before the next crisis.

Most interesting story, that was not particularly frightening or hopeful, or perhaps was a mixture of both:

  • Vehicle miles traveled have crashed during the coronavirus crisis. Vehicle-related deaths have decreased, but deaths per mile driven have increased, most likely because people drive faster when there is less traffic, absent safe street designs which we don’t do in the U.S. Vehicle miles will rebound, but an interesting question is whether they will rebound short of where they were. One study predicts about 10% lower. This accounts for all the commuting and shopping trips that won’t be taken, but also the increase in deliveries and truck traffic you might expect as a result. It makes sense – people worry about delivery vehicles, but if each parcel in the vehicle is a car trip to the store not taken, overall traffic should decrease. Even if every 5 parcels are a trip not taken, traffic should decrease. I don’t know the correct number, but you get the idea. Now, how long until people realize it is not worth paying and sacrificing space to have a car sitting there that they seldom use. How long before U.S. planners and engineers adopt best practices on street design that are proven to save lives elsewhere in the world?

metropolitan planning organizations

Leave a reply

If you live in a decent sized metropolitan area, your metropolitan planning organization forces local officials and other stakeholders to get together across political jurisdictions and make decisions about how to prioritize transportation projects in the context of a long term plan. The results then get sent up to the state, which uses it to allocate funding.

The article has a number of criticisms. MPOs have tended to favor highways over other forms of transportation, and these have often disrupted disadvantaged communities. They have tended to favor suburban areas. They have tended to favor new construction over maintenance of what is already constructed.

I have always thought MPOs are good even if they are imperfect because (1) they force stakeholders to work together at the right geographic and economic scale for infrastructure planning, (2) they force some kind of long term plan to be put down on paper, (3) they force the prioritization of site-level projects to be justified in the context of that long term plan, and (4) they bring in state and federal money to get projects in the ground based on the priorities of local actors that have “skin in the game”. In the absence of this process, either political jurisdictions would plan in isolation, or more efficient but less democratic structures would be created that largely cut out elected officials, voters and taxpayers. Engineers and officials not trained in planning would tend to jump right to analysis of site-level projects without a real plan. State and federal funding either would not happen at all or would be based on political lobbying. Corruption would likely be more common. And systems that are less in public view would tend to be neglected until major, obvious failures occur that affect peoples’ lives.

What I just described covers the state of water infrastructure in the U.S. pretty well. I think we should expand MPOs to cover other kinds of infrastructure rather than just transportation. MPOs are one of the reasons that politicians and the public think infrastructure=transportation and transportation=infrastructure. They do some rational planning and economic analysis at roughly the rate geographic scale and time period, then feed that into a messy political process to rank site-specific, short-term projects, then direct taxpayer money to projects that are likely to benefit the citizenry, while sharing the wealth at least a little bit. Unless you want to go authoritarian, it’s a reasonable approach to get infrastructure done in a democracy. I think it’s better and more equitable than the ratepayer-funded utility model followed in the water, energy, and communication industries.

10% drop in vehicle miles traveled predicted long-term

Leave a reply

KPMG says some of the sharp reduction in vehicle miles traveled during the coronavirus crisis is likely to be permanent, with people getting used to working from home and shopping online. The numbers they came up with are a 9-10% reduction in vehicle miles traveled (this factors in both a decrease in personal vehicles and an increase in delivery vehicles, if I understand the article) and a drop in car ownership from 1.97 to 1.87 per household.

solving the delivery problem

Leave a reply

Wired has an article on solutions to the “last mile” delivery problem. A couple interesting stats are that 5% of deliveries don’t reach their destination on the first try (that sounds pretty good to me) and that this costs retailers about $18 each time. Most of the proposed solutions just have to do with better data on locations and delivery preferences.

This article repeats the claim that deliveries increase traffic congestion, although it admits this is “difficult to measure”. I am still a bit skeptical of this. I am willing to follow the evidence wherever it leaves, but logically I feel like these claims leave out all the trips individuals are not taking to the store. If a delivery truck brings 100 packages to 100 homes, that could mean 100 car trips that were not taken. And that was just one truck, although it is kind of a big obvious smelly one and it might be blocking the street, a crosswalk, or a fire hydrant for a few minutes. Those trucks might also be competing for city and suburban streets at times when people are coming and going from work trips, which could increase peak traffic congestion.

Most frightening and/or depressing story: Most hopeful story:
  • I think Elizabeth Warren has a shot at becoming the U.S. President, and of the candidates she and Bernie Sanders understand the climate change problem best. This could be a plus for the world. I suggested an emergency plan for the U.S. to deal with climate change: Focus on disaster preparedness and disaster response capabilities, the long term reliability and stability of the food system, and tackle our systemic corruption problems. I forgot to mention coming up with a plan to save our coastal cities, or possibly save most of them while abandoning portions of some of them in a gradual, orderly fashion. By the way, we should reduce carbon emissions and move to clean energy, but these are more doing our part to try to make sure the planet is habitable a century from now, while the other measures I am suggesting are true emergency measures that have to start now if we are going to get through the next few decades.
Most interesting story, that was not particularly frightening or hopeful, or perhaps was a mixture of both:
  • I mentioned an article by a Marine special operator (I didn’t even know those existed) on how to fix a broken organizational culture: acknowledge the problem, employ trusted agents, rein in cultural power brokers, win the population.

#unblockbikelanes

Leave a reply

Just following up on yesterday’s “paint and pray” post about ignorant, unsafe street designs killing people in New York City and Philadelphia. There is a Twitter hashtag called #unblockbikelanes. Maybe the Philadelphia Police and Philadelphia Parking Authority look at it on occasion. Maybe they don’t. Maybe the engineers at the Philadelphia Streets Department will be inspired to learn about safe street design. Maybe they won’t. Either way, it’s indisputable photographic evidence that may eventually have a variety of uses.

August 2019 in Review

My work-life balance situation continues to not favor a lot of blog posts. Or is it work-life-family balance? Or is family part of life? Yes, I guess so. Anyway, what there is not a lot of time for is personal leisure activities like reading, writing, and thinking. Not that I don’t enjoy reading Green Eggs and Ham for the 50th time. I do. Anyway, here are a few highlights of the slim pickings that constituted this blog in August 2019. Most frightening and/or depressing story:
  • Drought is a significant factor causing migration from Central America to the United States. Drought in the Mekong basin may put the food supply for a billion people in tropical Asia at risk. One thing that can cause drought is deliberately lying to the public for 50 years while materially changing the atmosphere in a way that enriches a wealthy few at everyone else’s expense. Burning what is left of the Amazon can’t help. 
Most hopeful story:
  • I explored an idea for automatic fiscal stabilizers as part of a bold infrastructure investment plan. I’m not all that hopeful but a person can dream.

hydrogen as a jet fuel

Leave a reply

I was curious if aircraft could be fueled feasibly by hydrogen in the future. Okay, I know this has been tried in the past – “Oh, the humanity!” – but, there must be advances in technology since then. 10 minutes of research reveals that battery-powered aircraft are now a going concern, although they tend to be unmanned or at least small. Current fuel cell technology sounds like it has pretty similar limits to batteries. On a larger scale, there is serious research on the potential of liquid hydrogen as a commercial aviation fuel. It sounds feasible but would require major changes in long-lived infrastructure systems around the world. But let’s say you happened to have lots of electricity and water in abundance. Maybe you are in a coastal location and have invested in nuclear power, or you just happen to have lots of geothermal, hydroelectric, or whatever kind of power. You have also invested in desalination and you have created a major transportation hub. You might then be in a position to create liquid hydrogen and/or fuel cells at a cost-effective price. This could be climate friendly as burning hydrogen, in theory at least, creates only water vapor as a product, and fusing hydrogen with atmospheric oxygen creates the same – liquid water or water vapor. Hydrogen is dangerous, but so is jet fuel and so are the materials in modern batteries, so hopefully technology will eventually come to our aid and get the risk and environmental impact down to a similar or lower level than these other options.
