The Transportation and Mass Transit Megathread


TopTenn

Recommended Posts


I read with great interest the differing proposals for transit on this site, and in the local press. The problem is having a plan that can be executed.  That isn't to say that it can't be done, but the political realities as they currently exist at the state level does not give me much hope in the near term.  The majority political party are so philosophically opposed to mass transit in any form that it renders these ideas simply as a wish-list.  Without funding from the state transit will not happen, and they have not shown any interest in funding. Some day this will no doubt change, but it may take 10 to 20 years.

However, I do appreciate that mass transit is being discussed and some action is being taken.  When the time comes and the city can finally take action and with the cooperation of the state, and do something, hopefully we will have a plan in place.  In the meantime I hope that these guys spend a lot of time stuck in metro Nashville traffic as they meander back and forth from their rural outposts.

Hell, Yeah!  That's what I have said all along.  It often takes the misery of "constipation" before anything can get "through".

As has been the rule and the refrain by the choir, far too many opportunities have been forgone with the irreversible loss of "repurpose-able" resources throughout the core and within outlying districts (e.g. Green Hills), such that the costs for even a basic system framework will end up costing up to 4 times as much as it would have, had it been physically implemented as a start, as recently as 8-10 years ago.

Another summary of mass transit options from NBJ besides the link that MLBrumby gave above.  This shows that Gallatin might be the next in line for rail because of right-of-way that is available along Vietnam Vets Parkway:

The 'majority party' 's reluctance to blindly accept the mass-transit, pie-in-the-sky proposals is actually good governance. Fiscal discipline is why they are not enthusiastically opening the state's wallet to what is historically a boondoggle!

IMO, they need to start by being transparent on funding - select a small part of the project and prove they can complete it on time and on budget. Honesty and competence can go a long way towards convincing the powers that be of a minimal downside.

Interesting that they seem to be far less reluctant to fund highway projects that generally provide zero relief to traffic congestion issues. America used to take big and bold steps to tackle issues with infrastructure but now can only limp along until the next disaster forces action--at which point the original costs to fix have multiplied. The irony of the "historical boondoggles" is that many (most?) are the creation of the very politicians who use them as a scapegoat, either as a result of no-bid/preferred-bid contracts to their "friends" or forcing the acceptance of lowest-bid contracts through legislation.

But highway projects still are going to help the most people...or the majority of people.  Even if / when we have better public transportation, more people will use the highways.  So...we can't forego the highway infrastructure in place of mass transit. Mass transit has to be an "add-on".

Because they are not consistently wide enough, especially on bridges and overpasses. Also because shoulders are for emergency pull-overs...flat tires and blown radiators, etc. are still pretty common! 

The buses can still relocate onto the regular lanes if need be, though...

Can someone please explain to me why we can't have buses on the shoulders of the interstates (from all the outer counties) starting today, right now?

In addition to the above, TDOT uses a slightly different asphalt mix on the shoulders than they do the travel lanes, which isn't designed to handle the loads of regular traffic. This is why you'll often see contractors overlay the shoulders with new pavement prior to lane shifts for construction projects. Obviously BOS doesn't introduce much extra load onto shoulder pavement, but it will to some extent shorten its useful life.

Another complication is interchanges, particularly off-ramps that may become congested. There are conflict points between BOS and entering/exiting traffic here and use of the shoulder by transit vehicles can violate driver expectations, particularly in new systems.

In most BOS systems, buses use the travel lanes for the majority of the trip. Most have a hard speed limit of 35 miles per hour while operating on the shoulder; in addition, the speed differential between buses and vehicles in the travel lanes can't exceed 15 miles per hour.

In other words, buses won't use the shoulder unless vehicle speed in the travel lanes is less than 35 miles per hour, and in the worst-case scenario (traffic completely stopped) they have a maximum speed of 15 miles per hour anyway.

If TDOT were to hypothetically do a BOS study of the existing Interstate corridors, they would hypothetically find that the only segments of freeway where BOS provides a travel time benefit (e.g., where travel speeds routinely drop below 35 miles per hour) are segments where physical shoulder constraints (such as bridges, retaining walls, etc.) are common enough to preclude its use.

I think the Nashville MPO included some of this information in its managed lanes study, if you care to look.

I have been present and accounted on this board for for quite a while...much longer than yourself.

AMP was a failure from the beginning.....minimal input from many of the impacted communities for a plan that was ass-backwards..... they stated the route and mode and then decide to get input from the stakeholders... it did not go as expected. 

Identify a need (say a link from downtown to the airport) hold community input meetings, propose solutions that hopefully takes the non-skewed work product into account, produce the best compromise and DETAIL funding, costs, construction timelines...if they are reasonable and funding is found build the project and then check the final result against the projections. Pretty simple really...

Were you not here for the AMP debate? This is exactly why the AMP was proposed - to kick off the system with a small, well supported route that could be used as an example for other routes. But those who oppose transit said there needed to be a comprehensive plan in place first. Now that the plan is starting to emerge, opponents have reversed course with the argument you're making. Le sigh.

I love that Bridgestone built downtown... However I find it highly hypocritical that a company would accept a 20-year property tax abatement and $100 MIL in tax incentives and then cry that Nashville must invest in infrastructure ..... they add to the congestion and then absolve themselves of paying for the solution?!?! |
Crony Capitalism at its finest.

SS - maybe you should reread my post, 

"I love that Bridgestone built downtown..."

That does not absolve them of their hypocrisy...well not in my eyes... I will not speak for you.

RJ, I hope you are correct. It seems the chamber announcement would have provided just the stage for Nashville's Corporate community to have announced their funding to jumpstart the race for the money. I will drop this subject and save my virtual breath.

Good point.  A lot less talk and a little more action would have gone a long way to drive the point home on Bridgestone's part.
