SUGGESTIONS CHITTENDEN COUNTY REGIONAL PLANNING UPCOMING TRANSPORTATION WORKPLAN

The following suggestions were submitted for consideration for the transportation planning work program for 2012--anyone can submit suggestions and it is welcome that the agency has invited citizens to submit suggestions.:

Thank you for the opportunity to comment on the upcoming work program of the Chittenden County Regional Planning Commission (CCRPC).

Specifically, the Winooski public meeting asked:
"Help us develop new transportation planning and study ideas (such as intersection improvements, roadway corridor studies, traffic circulation analyses, etc.) for all travel modes."

First, in a prefatory note, the CCRPC and the Chittenden County Metropolitan Organization (CCMPO) literally spent tens of millions of dollars over the recent decades on the now defunct Circumferential Highway project, the misguided Dean train  (24 passengers a day versus a market potential about two dozen), and other poorly conceived concepts.  Might I be so bold as to suggest that at least proposed planning projects be approached with some sort of benefit/cost in mind.

Second, please note my blog this week,  TonyRVT.blospot.com which outlines the car travel trends in Vermont and Chittenden County--they trends are down with a likely decline in car travel this decade, a truly historic reversal of growth dating from the time of the Stanley Steamer.  The blog explains the demographics at work.  Meanwhile, the single digits growth of car travel last decade is dwarfed by far greater growth in bus, train, and probably non-motorized modes.

Now here are some suggestions for study:

1.  Study all County intersections technically for conversion to roundabouts with the assistance of a nationally recognized roundabout design firm--much of the rejection of roundabouts arises from the use of traffic engineers who see the roundabout as, justifiably, a threat to the jobs in their profession.  Further there are practically no other projects which can compete with the benefit/cost calculation for roundabouts at a busy intersection (note the earlier blog on all intersections but one signalized likely to be converted to roundabouts in Carmel, IN, a city of about 80,000 with lots of freeway interchanges).  After the base study, a prioritization scheme involving a public process can be undertaken for setting up which intersections/corridors/areas undergo roundabout conversions first.
2.  There are three studies of light density commuter/intercity rail dating from 1989.  Vermont is unique with all of its cities connectable by modern single unit  diesel-electrics similar to the Budd RDCs.  For Burlington, runs from Main Street Station in terms of commuter services could operate to Barre-Montpelier, Vergennes, and St. Albans.  Stops would include IBM entrance at railside and possibly the few hundred feet feeder to BIA.  These services would integrate to the larger intercity services using the same equipment statewide in part designed to shift basic transportation to the tourist industry from cars to rail passenger.
3.  The CCRPC needs to place emphasis on planning for those who walk, not those who bicycle whose interest groups have dominated the discussion and investments in non-motorized travel.   Actually, roundabouts are themselves are primarily a benefit and fostering of the walking mode--even though all modes and transit also benefit.  A roundabout qualifies as a bike/ped project too!
4.  It is fair to say that transportation planning and particularly projects in Chittenden County have failed miserably to serve business and economic growth and viability.  There are many blatant examples.  Can any state be pointed out with a poorer entrance for its largest employer than IBM in Essex Jct.?  A roundabout as an entrance at the Park Street and Maple Streets entrance would show that Vermont really is concerned whether IBM stays or leaves.  While the decades old Church Street Marketplace cannot be overpraised, the failure to expand the "shared space" elements along Bank, Cherry, and College Streets remains inexcusable--time to work on expanding "shared space" to bring merchants on those streets the same kind of expanded opportunity to draw customers as those on the Marketplace.  Other locations in the County need examination for "Marketplace-type conversion to shared space.
5.  Bike track needs to be installed starting in town and city centers--expanding off the Dorset/Kennedy Drive bike track type grade separated paths in South Burlington and off the Church Street Marketplace in Burlington.  For example, why not bike track from the Marketplace down Main Street to the Main Street Safety--with a roundabout first at Pine Street.  Such an installation might well have prevented the tragic fatality at Main/St. Paul in December 2010. 

There are other planning needs such as monitoring and reporting on "commuter choice" programs for all employers which utilize federal tax help to non-solo drivers (all walker deserve the same incentives when implementing "commuter choice"),  revising estimates of vehicle travel growth taking demographic changes into consideration, fitting housing development needs to changed demographics, and an examination of who pays and how much for each mode of transportation infrastructure compared to the costs they impose through use (heavy truck damage to pavements, for example).

UNDER 65 AGED DRIVER LICENSES DECLINE IN VERMONT

VERMONT'S RECORD LOW CAR TRAVEL GROWTH FOR 2000-2010 NO SURPRISE BUT THE SUDDEN FLAT LINING OF THE NUMBER OF LICENSED DRIVERS TOTALLY UNEXPECTED

The unprecedented drop of Vermont vehicle miles of travel (AVMT) growth to the single numbers for 2000-2010 comes as no surprise, but the sudden and unexpected flatlining of the number of licensed drivers for the decade 1999-2009 contains the seeds of a sharper driving downtrend in the immediate future.

Sure the State's population grows slower in recent decades—10% for the 80s, 8% the 90s, and 3% for the past decade. And, yes, an amazing collapse in car travel growth continues--a huge 57% increase in the 80s followed by 17% in the 90s, and when the dust settles about 8% for 2000-2010. The trend line suggests a very possible negative number for this decade.

But even more startling are the driver license numbers which after an average growth per decade 1980-2000 of 20% barely nudged 1% for the entire decade 1999-2009. For the first decade these numbers break down to an absolute decline in the number of drivers aged 64 of below, a negative 2.5%. Sure going to be hard to increase driving in Vermont when the number of the under 65 drivers decline in great part because historically senior drivers spend more time and travel on buses, planes, trains and ships while driving miles per year drops an average of 40%.

Of course gas prices increased well over average inflation and household income slid. But regardless of the price of gas and household incomes—neither is expected change in a positive direction significantly—the baby boomer aging out into the post-car age of 65 and above accelerates for the coming decade. This suggests an increasingly negative trend for driver license numbers and car travel. One U.S. Census projection for Vermont shows a flat under 65 population for the entire 2000-2030 period while the 65 and up population more than doubles.

There may be some other factors at work in addition to age in the driver license numbers. For example, some young folks unable to afford a car may delay driver license purchase and/or take time when a license expires to renew (or not renew at all). Licensing fees also increased above inflation during the past decade, certainly more than the increase in household income.

Meanwhile the tremendous growth in Vermont numbers using buses and Amtrak can be expected and it will be of interest to catch the trends of walking and bicycling. (Note the trends discussed here are not much different for other New England States though New Hampshire will be somewhat higher in population and travel numbers than the other five states.)

The data here comes from the Federal Highway Administration (FHWA) Highway Statistics Series, the U.S. Department of Transportation periodic survey of U.S. travel, and the U.S. Census data.

A WALKABLE, BIKEABLE, AND VEHICLE FRIENDLY MONTPELIER CORE

MAKING TRANSPORTATION SENSE IN THE HEART OF MONTPELIER, VT—A WORKABLE DESIGN FOR A TRULY CAR FRIENDLY, WALKABLE, BIKEABLE SPACE

Or would the Maquis de Lafayette on his 200^th Anniversary of his triumphal tour visit (1825) to Montpelier be able to have exclaimed: “Viva le espace Montpelier!”

 

There very heart of Montpelier presents an opportunity to shift from a frustrating mix of buses, cars, bicyclists and walkers to a shared environment benefiting all plus boosting the downtown shopping economy.

The basic area for attention: the very central core of the built up area--parts of Main Street, State Street (the City's “sacred street”) and its extension, East State. The street sections are: (1) the three blocks on Montpelier's Main Street from the Winooski River Bridge to to the front of Kellogg-Hubbard Library; (2) State Street from the Post Office/Capital Plaza Hotel to State/Main; and (3) from East State from Main to beginning of the upgrade just past City Center. All changes can be measured to a high standard of comfort, ease of movements without significant delay, and safety—for all users.

Confusion now reigns...

Each section of these streets presents a substantial confusion for all users. There is the section from Barre Street to the Bridge with its the mix of cars and buses plus rail traffic, Shaw's market entry/exit traffic and Stone Cutter's Way entrance always challenge vehicles with left turning traffic often suffering irritating delay. The rail corridor from Main Street west past Shaw's stands as jpart of the planned route connecting the East and West Winooski multi-user bikepaths. (The City plan done with consultant firm Wilbur Smith led to a recommended connection featuring a roundabout at Barre/Main.) The section from Barre Street to Kellogg-Hubbard Library contains the State/Main/East State four-way intersection with a rather long wait cycle for all traffic streams and walkers. Add to this the School Street intersection, a wide area where a walker fatality and other serious injuries have occurred; and the Langdon Street walker crossing because of the adjacent signal seriously conflicts with Main Street vehicle traffic.

From Barre Street to the Library key shopping, City Hall and Fire Station, and City Center generate a constant and varied movement by walkers, bicycles and various motor vehicles throughout the day. Finally there are the several accesses to behind Main Street parking lots with the lack easy access to those lots a downer for shoppers, visitors, and those seeking downtown services.

While State Street improvement installing angled parking in front of the Post Office deservedly received praise the project still left unaddressed problem Elm/State Streets intersection. On East State there is the obvious speed transition of the down grade to flat extending west from the City Center Parking ramp and parking area entrances on the south side—not big problem but one which could be easily addressed by a traffic calming measure.

The long term vision includes “shared space,” a low 0 to 5 mph typical (10 mph maximum) context with all modes mixing, a context where vehicles (including bicycles!) yield to those who walk. This is the safest form of street context, based on experience in Europe where the first installations occurred. The Church Street Marketplace in Burlington (VT) gives a flavor of shared space where College, Bank and Cherry Streets intersection feature a mingling of Marketplace walkers with streams of vehicles, all vehicles operating about 5 mph and yielding at slightest movement of a walker making even a late decision to cross anywhere in the intersection. As a practical matter today, along the sections in Montpelier discussed here a driver who takes care to be ready to yield to walkers can only move at realistically at about 5-7 mph during much of the day—this needs to be kept as a backdrop when considering various treatments suggested below.

The transformation of the core of Montpelier to “shared space” can be viewed as a two-step process with several elements involved in each step. The first step involves installation of infrastructure to enable reduction of speeds and accommodation of bicyclists. Once the infrastructure is in place, the second step is one mostly of process as the City Council working with citizen-driven committees (really starting from the outset and involving both the Planning and Public Works Departments) to slowly and deliberately change the rules and make minor alterations street elements to a final form: a safe haven for walkers and bicyclists while enhancing the experience and efficiency for for cars. That result particularly benefits the business community and their customers as both comfort, ease of movement, and reduced delay all add to a radically improved retail environment.

What distinguishes “shared space” in its pure form from an urban center traffic calmed area represented under the “first step” come from eradicating all signs and signals (the one signal in the Montpelier case gets replaced a roundabout at the beginning stage). Further, the final form of shared space usually involves removal of curbing—again think of the Church Street Marketplace intersections.

The “infrastructure”

Existing Plans

Some of the changes infrastructure already exist or can be found in various downtown plans, often from citizen-driven charettes and studies. First, the Keck Circle roundabout already acts to slow traffic at the northern end of the Main Street corridor and enables ease of reversing direction for tractor-trailer business servicing trucks (traffic data indicates about 40 tractor trailers a day traverse Keck Circle). The excellent project at the post office block reduced speeds on adjacent street segments. The planned 90-foot-diameter roundabout, like Keck Circle accommodating all vehicles, at Barre/Main keying the connection of Winooski East and West Bikepaths also establishes a major component of enabling traffic movement at a congested intersection as well as enabling access to the parking areas behind the west side Main Street buildings. (An immediate installation of a demonstration mini roundabout at practically no cost might well help demonstrate what a full roundabout can accomplish--”try before you buy.”)

Various past City planning documents include a number of possible new walker paths, such as (1) the “Kitzmiller” walkway advocated by the late Rep. Karen Kitzmiller connecting State and Langdon Street along side/over the Worcester Branch; (2) a below State Street walker bridge between the Farmer's Market area to the parking area behind Main Street; (3) the elements which connect the East and West Winooski Bikepaths (Wilbur Smith study); and (4) the east Worcester Branch riverbank from State to the rail bridge.

 

The “infrastructure”:

New key elements

There are at least four other major infrastructure elements which allow collapsing Main Street to mostly two traffic lanes and enable bike lanes and other street improvements as less space is devoted to vehicles and more to walking, bicycling, and street amenities —and in the case of East and West State Street, low enough speeds and/or lanes enable bicycles to be reasonably accommodated. Note when Keck Circle came about the extra space, once used for turn lanes no longer needed with a roundabout, immediately became valuable parking spaces.

The four other major infrastructure elements are:

1. A min-roundabout at State and Main

Not enough room exists to accommodate a full roundabout (minimum 90 foot diameter) at State and Main (like Keck Circle or at Main/Barre). A roundabout which allows all movement except left hand turns could be installed, but with the restricted options for movement of emergency vehicles, particularly fire apparatus so that a mini which enables all turns to be made is the realistic choice. With nearby roundabouts and traffic calming elements safety for walkers is enhanced (anything but a roundabout generates up to a 900% greater rate of serious injuries, the Insurance Institute for Highway Safety tells us). And there is a tremendous reduction in walker delay—one study show less than three seconds delay and anyone can test their own delay experience by just checking out delay at Keck Circle.

2. A normal roundabout (like Keck Circle) at School and Main This roundabout pairs with Barre Street Roundabout and a speed table adjacent to Stone Cutters Way providing full traffic calming from Keck Circle to the Bridge. With speeds constrained north bound traffic desiring to turn left onto Langdon Street should find ease of entry, but if southbound vehicles to not oblige then a turn-around at the School Roundabout enables a quick alternative and easy right hand turn. Again, a demonstration mini at little cost be installed at any time to get the basic benefits of a roundabout without further waiting, benefits including increased safety for walker and vehicle occupants and reduced delay for all.
3. A mini-roundabout at Elm/State Streets The Elm/State Streets intersection is especially difficult because of the angled approach of Elm to State and lack of room for a full size roundabout. Not only will traffic on the three legs move with little delay or backup, but access to and from the “garage” parking area will be eased. (Note this intersection along with Keck Circle, Spring and Elm, and State and Main together represent the four corners of the basic downtown circulation network, essentially a rectangle supplemented slightly by School as a cross-street midway between Spring and State.)
4. Other elements Other elements—some requiring more discussion and analysis—include use of traffic calming (mostly speed tables) to manage speeds on State and East State, possibly through employing raised crosswalks. A “bike track,” a grade separated one or two way bikeway may be explored for parts of all of the street sections under consideration—bike tracks are the type of on-street bikeways in Montral with curbing separating the bikeway from vehicular lanes.

Some final considerations

This outline provides a vision which may be modified, like all visions there needs to be a planning and development phase, but some elements like the roundabouts can be installed at a fairly rapid pace on a prioritized basis. The traffic volumes in the street segments in downtown Montpelier—like most of the County—have changed little or have actually declined since about 1990. Traffic patterns now involve little change and if anything a drift downward. Single lane roundabouts or mini roundabouts easily handle the current and future traffic loads. (Note that from 2000-2010 statewide traffic grew in the single numbers for the first time since emergence of the automobile a century ago.)

There are at least to strategic considerations. As Vermont traffic numbers plateauing and even declining, and with costs of maintaining low volume State roads sure to be an issue, discontinuing VT 12 starting at the Winooski River Bridge north to Morrisville could be a good candidate for removal. First, perhaps 200-300 vehicles actually travel the length of that roadway section daily, and, second, two parallel roads—VT 14 and VT 100 provides alternate routings. Discontinuing VT 12 north of Montpelier would reduce a small but significant amount of Main Street traffic, particularly tractor-trailer numbers which total about 40 a day at Keck Circle.

A second strategic consideration remains the Washington County Railroad (WACR). It is very possible, even likely, that self-propelled single unit rail passenger equipment may connect Barre-Montpelier with a few trains daily to Burlington (there are three studies which relate to this possibility dating from 1989). Such a service which would likely begin in Barre and use the Montpelier transit center as envisioned off Taylor Street would as a practical matter cross Main Street and that potential needs to be kept in mind while planning and developing a “shared space” central downtown traffic design.

Finally Vermont gets it first “mini” roundabout in Manchester Center this year as part of a two roundabout project. The mini at Main/Bonner Streets, VT 7A/30 is about a football field north of “dysfunction junction” VT 7A/11 (Main and Depot Streets, being renamed “function junction” by local leaders in advance of the regular roundabout). Manchester Center is the first town center in the nation to have an all-roundabout circulation plan (1995).

CITY GOAL: BECOME A ONE TRAFFIC SIGNAL TOWN WITH 100 ROUNDABOUTS

ROUNDABOUTS IN CARMEL, IN—ONE TRAFFIC SIGNAL AND 100 ROUNDABOUTS, AND THE TIDE RISES TO THE INDIANA DEPARTMENT OF TRANSPORTATION (INDOT)

The leadership of four state and provincial transportation departments which adopted “roundabouts only” policies masks the individual town and city leadership in the U.S. roundabout revolution. (New York since 2005, Virginia, British Columbia and Alberta represent the current jurisdictions with “roundabouts only” policies.)

Two recent related news reports presents a clear picture of the interaction of local leadership resulting change at a state department of transportation. First, the Economist reports the Carmel, IN, population 79,191, emergence as U.S. roundabout capital. Second, the Indianapolis Business Journal last week documents how the Carmel innovation and experience fosters a major investment in roundabouts at INDOT.

Carmel [IN], just north of Indianapolis, has 70 of them [roundabouts]...The mayor, Jim Brainard, built the first roundabout in Carmel in 1997...It was so successful that today Carmel is the roundabout capital of America and the mayor plans to rip out all but one of his remaining 30 traffic lights.”
The Economist November 19, 2011

INDOT [Indiana Department of Transportation] has identified 31 intersections statewide for roundabout construction over the next five years, including a dozen in the [Indianapolis] metro area.

That’s less than half of Carmel’s 70-plus roundabouts—but a tenfold increase from the three roundabouts INDOT has today.

IBJ.com [Indianapolis Business Journal] January 7, 2012

A look at the Carmel “Thouroughfare Pan Map,”

http://carmel.in.gov/index.aspx?page=211 gives a picture which looks like a two-dimension tinker toy design with lots of sticks connected by those cylindrical pieces. The City also has more than a dozen freeway interchanges, including an interstate. The “one traffic signal-100 roundabouts” goal of Mayor Brainard along with the department and provincial “roundabouts only policies” brings into question why other jurisdictions continue to install and upgrade, essentially, unsafe and obsolete traffic signals. Besides, roundabouts foster a vibrant walking mode, reduce fuel use and pollution, aid public transit, reduce delay for all, beautify and enable higher density land use and constrain sprawl pressures. Finally, the facts here suggest that the traffic engineering community itself need to consider the professional ethics of continuing to recommend design new and upgraded traffic signal systems.

CITY GOAL: BECOME A ONE TRAFFIC SIGNAL TOWN WITH 100 ROUNDABOUTS
