		<description>&lt;blockquote&gt;I wonder if there are any opportunities for neighborhood feeders to take the load off some of the P&amp;R lots? &lt;/blockquote&gt;
Maybe for some of the major close in lots like Eastgate, South Kirkland, Mercer Island. But the ongoing cost of running the bus service (~$6 per boarding would be my guess) gets you pretty close to the cost of funding a bigger garage. At some point I&#039;d hope that there would be a fee for parking. Charging a reduced fee (or free) for carpools would help free up spaces.

It&#039;s the &quot;far out&quot; locations for new P&amp;R lots I was thinking of. Mini lots of a couple hundered cars would support Eastside routes into Bellevue for transfers or perhaps direct to Seattle. The advantage is you intercept traffic before it gets to the most congested points. Several small lots along say SR-522, SR-203 or SR-202 would be sort of like local service rather than requiring a drive into Woodinville, Mill Creek or Redmond. I think it&#039;s also easier to locate small scale developments. And land always seems to be a good capital investment. Maybe some of lots along the BNSF Woodinville Subdivision could someday become train stations.</description>

		<description>I wonder if there are any opportunities for neighborhood feeders to take the load off some of the P&amp;R lots? Obviously with full P&amp;R lots the choice is to either build more storage for cars at great expense or make it so at least some suburban transit riders don&#039;t need to drive to the nearest P&amp;R.

As for Aurora/99, I suspect there is enough demand to justify going straight to rail. Besides rebuilding it along the same lines as MLK was rebuilt (though with more through lanes and possibly with an elevated guideway and stations) would do a lot to make the street much more pedestrian and bike friendly. On top of that due to all of the auto oriented businesses Aurora is relatively low hanging fruit for TOD.</description>

		<description>My viewpoint is obviously eastside oriented but mainly what I see is chock full P&amp;R lots. I&#039;m not convinced expanding any more of these with expensive multilevel parking garages makes sense but I think there&#039;s lots of opportunity to buy more outlying land on say the SR-522 corridor, SR-202, and such which would fill if we had the funds to support them with more bus routes. I can&#039;t really think of anywhere except Aurora/99 from Shoreline north that&#039;s really ripe for true BRT. The Transit/HOV lanes on 405 and SR-520 need immediate attention. I don&#039;t think it&#039;s much more than making it HOV 3+ on 405 as soon (or sooner) as they finish the current lane expansion projects. On SR-520 it&#039;s the switch to an inside HOV lane that&#039;s required. I was told by WSDOT reps at the last open house I attended on the SR-520 corridor that this was partially funded and would proceed independant of the bridge construction. They were hopeful of a 2012 time frame.</description>

		<description>Bernie, you statement obviously depends on what &quot;high ridership&quot; is, but my view is that you&#039;re pretty much maxed out unless you&#039;re talking about qualitatively improved service like RapidRide.

The next quantum leap in ridership is going to come from quality (RR, rail, whatever) and better land use.</description>

		<description>Land use modeling is not my forte, but I was surprised to find that the variations in land use observed in each scenario were very minimal.  In &lt;a href=&quot;http://www.psrc.org/assets/1941/appd.pdf&quot; rel=&quot;nofollow&quot;&gt;the PSRC Transportation 2040 DEIS Appendix D&lt;/a&gt;, the graph on page 77 (79 in the pdf) showing the variations was really surprising.  There is virtually no variation in land use regardless of the alternatives.  It&#039;s hard to say whether the land use growth model is insensitive to transportation infrastructure or if the land use development strategy is so rigid that growth will occur in these ways regardless of what infrastructure is built.</description>

		<description>There is no shortage of opportunity to implement bus lines that will receive high ridership. What there is a shortage of is funding to create these routes. Public transit is subsidized to the point that whatever you build (if it&#039;s not just plain stupid) will attract near capacity use during peak commute hours. Right now buses are the best value on attracting new transit users, reducing VMT and offering an alternative to congestion. Sounder is great (well, at least south of Seattle). Link should work out fine; replacing bus miles at a savings, improving air quality and hopefully attracting new riders and aiding in urban renewal along much of it&#039;s route. But better bus service is the bread and butter of increased transit mode share.</description>

		<description>I don&#039;t agree with your view of history.  Yes, rail cities build one line at a time, of course.  But few feel that they need each line to get 40 miles away to the next city before they start on the next line in their network.  That&#039;s a political deal that is unique to the Puget Sound, in order to distribute the money around a 70-mile long service area encompassing three cities.  There may be one or two cities in the world with 70-mile-long light rail lines, but in most cases that is well into the domain of commuter rail and express buses -- since the station spacing required to make rail competitive over that distance is a lot longer than what is considered desirable for light rail.</description>

		<description>I&#039;m with John Niles on this one - PSRC needs to come up with a model that doubles work trips AND non-work trips.  Based on the experience of just about everywhere outside the US, much higher transit mode shares are quite feasible.  And since 80% of the total trips are non-work trips, we need to provide people reasonable alternatives for these trips to make a region-wide dent in VMT and greenhouse gases.

The PSRC alternatives assume minimal transit improvements beyond baseline (ST2), and may not accurate model changes in land use, and that is why they don&#039;t deliver the mode share.

Some ideas:
- Buses running at 10 minute intervals on all arterials in the UGA
- A frequent, two-way Sounder network for longer distance travel (incl. Eastside rail)
- An extensive light rail network (i.e. more than a single 60 mile spine) that goes to most sections of the city and most suburbs, for medium-length trips.
- Supportive land use and street connectivity

Expensive, yes.  But expensive compared building highway infrastructure for all of these trips throughout an ever sprawling metro area?

With an integrated system like this it becomes convenient for many throughout the metro area to use transit (or to walk, bike or unicycle) for everyday errands.  And no, a clean, well-lit low-floor bus that runs every 5 minutes and goes exactly where you need to go is not intrinsically less attractive than a car.</description>

		<description>I totally agree with Greenwood Rider, and that&#039;s what I meant above about how you can&#039;t put a car in your pocket and take it out later.  When you have a chain of trips to make, you have to do them all by car or none by car.  You can drive to work, to the store, to home. Or you can ride transit to work, to the store, to home. But you can&#039;t drive to work, ride transit to the store, and drive home, without going back to work to get the car. 

Peak-hour transit to work sites is essential, and it increasingly attracts suburbanites who are willing to ride to work but not to use transit otherwise. Though after time they&#039;ll start using transit for a few other things, especially going downtown, or when their car breaks.

Off-peak transit is important, not just for shift workers and carless households, but so that people can use transit for multi-trip chains. If the bus goes everywhere I want to go today and tonight, I might ride it. If it stops at 9pm or doesn&#039;t go where my evening activity is, I&#039;ll drive all day, even though I could take the bus to work and back and then get out the car. Or maybe I can get a bus to the activity at 7pm but not back home at 10pm, so I&#039;ll have to drive both ways.

London&#039;s tube was built primarily to get working-class workers to jobs, but it was consciously extended to 18 hours a day to make carless living feasable.  (Of course, motor cars didn&#039;t exist when it was originally built.)  Likewise, the PATH trains from NYC to New Jersey are called &quot;commuter trains&quot; but they run 24 hours every 5-15 minutes, making a carless life feasable.  The Caltrain in SF runs one an hour till 10:30pm, and every two hours on Sundays. Not so good for carless living. And Sounder runs only peak hours: forget it unless you&#039;re going to work in those hours.</description>

		<description>They generally do convert HOV2 to HOV3 the worse traffic gets.  Maybe 405 hasn&#039;t kept up.

I don&#039;t know of anywhere that has more than one HOV lane on the same road. That would be a big social change to limit SOV traffic to one or two lanes.  Maybe someday. (Unless Tim Eyeman passes an initiative to prohibit it.)

There&#039;s an argument that HOV lanes don&#039;t exactly do what they intended to. A carpool is when multiple people who would otherwise drive separately, drive together.  But a family outing is not a carpool because the kids can&#039;t drive and ma and pa want to travel together (that&#039;s the purpose of the trip). And UW students pick up people next to campus so that they can qualify for the cheap HOV parking spaces. In most cases people don&#039;t have a choice whether to take one person or multiple people on the trip; that depends on outside factors. You can find somebody to carpool to Microsoft with, but you can&#039;t find somebody who wants to go to the store at the same time you do. HOV lanes are great for providing a speedy lane for transit, and they discourage SOV driving in the abstract (although that hasn&#039;t cut the number of SOVs on the road!), but their ability to increase carpooling has been less effective.</description>

And UW students pick up people next to campus so that they can qualify for the cheap HOV parking spaces. In most cases people don&#8217;t have a choice whether to take one person or multiple people on the trip; that depends on outside factors. You can find somebody to carpool to Microsoft with, but you can&#8217;t find somebody who wants to go to the store at the same time you do. HOV lanes are great for providing a speedy lane for transit, and they discourage SOV driving in the abstract (although that hasn&#8217;t cut the number of SOVs on the road!), but their ability to increase carpooling has been less effective.<!-- google_ad_section_end --></p>

		<description>It sounds like transfers skew the numbers.  If I walk to a bus stop, that&#039;s me making a choice.  In NYC if you take two subways to reach a destination, that&#039;s technically two trips but effectively one trip, because the system was designed to be one big virtual line, as is shown by the one-trip farecard charge.  When Metro split the 43 into the 43 and 44, that suddenly made one trip into two trips without the rider doing anything to cause it.

So the effect of this split is ambiguous. Overall it helps people by making the buses more on time. But it inconveniences those whose trip was suddenly split. But if Metro funding depends on more trips, it&#039;s good.  But if Metro funding depends on more one-seat rides, it&#039;s bad.  Counting by passenger-miles benefits those who take long trips but disadvantages those who take short trips (by shifting money away from routes that are predominantly short trips; e.g., the 2 vs the 358).</description>

		<description>This isn&#039;t a shift in density, just a different sampling size.  What you see are households that completed a household survey.  Not every household will complete a survey, but based on the total population obtained from a census for example, the results from the households that were sampled can be expanded to a value for that particular area.</description>

		<description>The whole point of a household survey is typically to obtain parameters for use in developing a travel demand model.  While it is possible to measure such discrete things such as the cars people own and how far they drive, it is also important to eventually model where all this activity takes place so the number of trips can be estimated in the travel demand model.  Using the output is supposed to help regional planning organizations and cities plan for future growth.</description>

		<description>No, the big takeaway from all of this is that work or school trips are the important measure.  People tend to make those trips 5x/weekly, and if they&#039;re using transit, they&#039;ll probably do some of their errands on the way to and from work.  This is where you get 80% of your results in moving people from 20% of your effort.

Transit relieves congestion, &lt;i&gt;for the person using the transit&lt;/i&gt;.  Regional society, which is paying the bill, does not experience this relief- road usage rises to congestion levels that act as an informal tax, and stays there.  Congestion is just a characteristic of road vehicles, and should more properly be treated as a turbulent flow condition.

If you were to read the history, you would find that the cities with dense networks did not build dense networks- they simply built one line at a time, over and over again.  Naturally, there will be a few exceptions to this rule, but that is generally the case.

It&#039;s important to remember that your ability to make all your trips by transit is largely the result of destinations being built where the transit goes, rather than transit going to the destinations.  The instances of a tram stop being built for the Opera House are vastly outweighed by the housing and commerce built near the tram line.

Finally, the ability to ride transit to work makes or breaks the deal for most of us.  If you need a car to get to work, you&#039;re probably going to own a car.  If you don&#039;t, it becomes a dispensable luxury.</description>

		<description>But the household surveys are like the Radio Diaries that the radio ratings services just dumped.  They depend on the user to accurately fill out the log and as we see above, it is far easier to miss a transit trip than it is to miss an auto trip because while the auto trip is begun and ended by (usually) a turn of the ignition key, a non-auto trip can be made sub-consciously.

The move to an electronic measure of radio listening has led to a huge revamp in the radio ratings biz.  May I suggest a similar move in the world of trip data collection?  

But again it will ALWAYS favor the car, because the car only requires the gentle push of an accelerator.  

Even a paraplegic can travel solo by car.  They&#039;re not likely to ever travel as much or as far in an unpowered wheelchair!</description>

		<description>&lt;blockquote&gt;but the notion that commute trips are more important than non-work trips, or that battling congestion is more important than other transit objectives doesn’t sit well with me. That’s a car-oriented approach. You can’t just put that out as a truism.&lt;/blockquote&gt;
What you put forth is altruism. It&#039;s the commute based trips that make transit economically feasible. The reason a tourist can go to London and take the tube anywhere in the city is because that system gets millions of people to work everyday in a density where cars simply can not work. Of course high capacity transit also benefits from consistent demand so enhancing off peak trips where ever possible through routing or TOD is synergistic.</description>

		<description>I know this won&#039;t go over well here -- but the notion that commute trips are more important than non-work trips, or that battling congestion is more important than other transit objectives doesn&#039;t sit well with me.  That&#039;s a car-oriented approach.  You can&#039;t just put that out as a truism.

When I think of great rail cities I&#039;ve lived in or visited, the most important advantage that rail has provided is to be able to make *all* my trips on transit rather than only my work trip.  It&#039;s a no-brainer to use transit (whatever mode) to get to work.  It&#039;s another thing entirely to tour a city by transit (needs a network and stops wherever pedestrians want to be concentrated), or to use transit to visit friends across town or take your kids to school.  For those trips, the visibility, frequency and simplicity of rail give it an advantage that isn&#039;t as important in the decision to use transit to work - the same trip at the same time every day.

I don&#039;t particularly care, living mostly in cities or metropolitan areas, whether rail extends 40 miles out - it doesn&#039;t add a lot of value over buses.  The place where rail adds value, in my experience, is for transforming the way I can make all the other trips in life - the non-work trips that make up the vast majority of trips, tours, whatever.  And the cities that have done that particularly well have adopted a dense urban network rather than a model of getting to cities 40 miles away.</description>

		<description>Digging deeper (wear your boots) I&#039;m looking at the map on page 9, &quot;travel survey household locations, 1999 vs 2006&quot;. I would expect the density map to follow growth trends. Maybe they do but I&#039;m seeing a 1999 West Seattle density similar to east King County. Major increases in density in downtown Tacoma (maybe I missed it) and a decrease in density for Mercer Island, Bellevue and Kirkland (didn&#039;t see that one coming). Maybe this reflects a shift in relative density but it sure raises a question mark for me as to how much you can relate the results between the two surveys. Not only are there major physical differences between a &quot;trip&quot; for someone in Silverdale vs. Mercer Island vs. Capital Hill but the very nature of the way they will tend to fill out the diary I believe will be different.</description>
