SkylineView Posted November 6, 2017 Share Posted November 6, 2017 (edited) Grade separation came up several times as part of the "how would Houson get high speed rail to downtown" question. I can't find the links, but one of the options was a plan to put two lines each of freight and high speed rail deep in a trench. I also recall there is (or was) a long-term vision to build underpasses for Shepherd and Durham under Washington.

There are at least twice as many apartments within 1/4 mile of Washington. Add in all the townhomes. It would stop at the NW transit center, so add all those. It's a few more than just 400 people. There's a census tract covering around 1 sq mile, roughly centered on the intersection of Wash and Studemont with 4616 people (probably more now). Population density is similar throughout the Washington corridor: mid-4-figures. Call it an average of 5000 /sq mile across the corridor. This is largely a residential corridor, but let's assume that for every resident, there's 0.5 jobs in the area as well. That's an activity level of 7500/sq mile, or about 12/acre. A UC Berkeley study estimates that, for a light rail project to be cost-effective at capital costs of $50M/mile (the green/purple lines cost about 3X this much), you'd need an activity level of 60/acre. So we'd need to not only reduce the cost per mile by 2/3, but also increase activity density by of a factor of 5 as compared to 2010 levels. Most of the corridor is still single-family residential, albeit now with 3000-sf townhouses instead of 1200-sf bungalows. It's possible for neighborhoods made up of single family houses to get to 30,000+/sq mile, but not with our current development rules, with wide right-of-ways, mandatory setbacks, and off-street parking minimums, all of which limit density to levels well below those needed for workable transit.

JJxvi Posted November 6, 2017 Share Posted November 6, 2017 (edited) I have always been extremely enthusiastic about rail and think its great, but I don't see how expansion of light rail as currently implemented in Houston can possibly be considered without a real rethink of how transport has already changed and will change in the future. The rise of app driven ride sharing and the possibility of self-driving transport on the horizon we live in a much different world than we did in 2003. The type of rail we built seems less cost and time effective now than it did then, IMO. Edited November 6, 2017 by JJxvi 1 Quote Link to comment Share on other sites More sharing options...

The type of rail we built seems less cost and time effective now than it did then, IMO. currently, with ride sharing, I'm more likely to take mass transit, at least to get to a destination. Who knows when I need to bolt when I'm out, relying on trains is okay, but in a city where the transit doesn't run 24/7 I can't rely on it to get home after a night out. Also, buses are pretty horrible as far as being on time. so with ride sharing options guaranteed to get me home when I'm ready to get home, I'll take mass transit to where I'm going and get an uber to go home. a fun trick when you're dealing with surge pricing after a football game (or similar) take mass transit towards your next destination, set up for an uber to pick you up at a starbucks along the route. you're closer to home and out of surge pricing. Looking to the future, I think mass transit will thrive in a world where humans don't operate the vehicles. I'm talking all the vehicles, including the mass transit vehicles, buses and trains. they would all talk together to give appropriate priority, left and right turn lanes could easily be re-introduced onto the rail lines where they were removed.

I agree, but maybe for a different reason. The biggest impediment to workable transit is a lack of density. And the biggest impediment to achieving sufficient density is the requirement that every development provide parking. (There are others, but this is the biggest.) Once cars can drive themselves, you can de-couple parking from the destination. Even if the dominant model remains everyone having their own personal vehicle, if the cars "valet park" themselves, then you can eliminate the rule that off-site parking can only be a short distance away. That opens up a ton of land area for additional commercial and residential development, which could result in corridors with enough density to make transit work. 4 Quote Link to comment Share on other sites More sharing options...
JJxvi Posted November 13, 2017 Share Posted November 13, 2017 (edited) I agree and hope completely that self driving cars probably leads to an increase in urban density due to scrapping the on-site parking. However, I still don't think it plays well with Houston style light rail. I think self driving taxis will be infinitely more popular and desirable than the type of local service light rail we have now. I am bullish on more rapid long distance transit like commuter rail, which I previously didn't think would really work until an inner city transit network was built out.

This is why fixed guideway transit is economically challenged. We're better off just building much denser neighborhoods and let transit patterns grow up around them. 1 Quote Link to comment Share on other sites More sharing options...

bobruss Posted November 15, 2017 Share Posted November 15, 2017 I'm not looking to get everyone to take mass transit. I just think that its a great alternative to getting more cars off the road and if that helps the people who don't or can't take mass transit then hopefully it will help them navigate the streets much easier. It also cuts down on emissions. 2 Quote Link to comment Share on other sites More sharing options...

And, despite being crowded at times, I prefer them over driving a car stuck in rush hour. Standing is also healthier than sitting. Generally, even when the train is empty, i will stand. If I do sit, I will certainly give up my seat for an elderly person or a person with infants, etc. 1 Quote Link to comment Share on other sites More sharing options...

I don't necessarily think that's true. I think there's a maximum level of traffic and commute time that the average commuter is willing to tolerate. The congestion will generally reach that point, and there will be a break-even point where any inflows of traffic would be balanced by diminutions due to avoidance of the congestion. I think that, once roadways reach capacity, the inbound destinations would have lessened growth without added capacity, with outlying areas tending to take that growth. Mass transit just allows for added capacity to move people into the central destination. As opposed to, let's say 700,000 people going into Manhattan on a given work day with only the option of automobiles, we get 1.5 million (just making up numbers here merely for illustrative purposes) people going into Manhattan. The average commute gets to that upper bound and then the inbound commuting population levels off. The commute time issue applies to mass transit as well. The average person isn't going to wait for an hour in line to get onto overcrowded trains. They'll just find something closer to where they live or relocate to somewhere where their desired commute can be achieved. If you don't provide the additional options for inbound commuting, suburban job growth will occur to respond to the demand for lower commute times. Shortened version: I think the line that mass transit alleviates congestion isn't actually true. Mass transit just allows for added capacity to permit additional growth of certain areas.

Denver? Seriously? I've made the drive to the Denver Airport many times both before and after they had rail service. Trust me. There is zero discernible difference in the traffic. I am being completely factual, as usual. And you are arguing against straw men. Yes, mass transit can be and should be a factor in our city (and is a factor in our city, but I agree it should be a larger factor. To say that there are no examples of cities where mass transit has eliminated or significantly reduced congestion is not to say that mass transit has no role.
