You may have noticed the recent appearance of painted white bicycles under a double arrow on campus streets. They are sharrows, and they come with a message: It’s time to share the road.

These awesomely hip shared-lane markings are a nationally recognized symbol alerting road users that bicycles have a right to occupy the lane of traffic. In addition to alerting and slowing drivers, the arrows serve to indicate to cyclists the appropriate direction of travel.

Recognizing that many streets on campus are not able to accommodate a separate bike lane, the sharrows help tell both drivers and bikers that cyclists have a right to move into the center of the travel lane.

There are several scenarios in which we might acknowledge this to be safer than staying on the side of the road. For one, this helps to ensure safe passing of parked cars by cyclists and gives people exiting parked vehicles enough room to open doors. In addition, it also locates cyclists in a more visible position to cars approaching the roadway from side streets and driveways.

These sharrows play an important role in biking safety. The N.C. Department of Transportation’s data on bicycle crashes reported in North Carolina between 2005 and 2009 indicate that 7.8 percent of collisions involving a motor vehicle and a cyclist occurred when the motorist was overtaking the cyclist. Sharrows should help. Because bicycles move more slowly, vehicular traffic must adjust their speed accordingly. On campus, where the speed limits don’t exceed 25 mph, the sharrow effect may simply serve to reinforce this limit. That’s safer for everyone, including pedestrians, who always have the right of way!

One place you won’t find sharrows is on the paths and walkways around campus. Pedestrians have the right of way in these spaces and it is dangerous for cyclists to ride through these areas. A dismount policy, particularly for the heavily trafficked Main Quad and Bryan Center Plaza are appropriate and encouraged.

The introduction of the sharrow to campus streets is not intended to address the remaining need for a cross-campus, bike-friendly connection.

The sharrows compliment recent efforts to map bicycle infrastructure, including bike racks and shower facilities, and improve commuter incentives. This should result in the continued growth in popularity of cycling as a viable commuting option, despite the limitations of existing infrastructure.

Recently released statistics from Duke Parking and Transportation indicate that more than 520 people are registered as bike commuters, roughly 60 percent of whom are graduate students. These individuals are likely to live between two and five miles from campus. This makes the Duke-Durham connection to campus critical for heightened safety door-to-door. Duke should continue to partner with the city to make these connections a viable priority.

The sharrow program also enables the continued encouragement of undergraduate students to bring bikes to campus and to utilize the highly popular Duke Bikes program.

Another opportunity to expand the bike user base will continue to grow as bus and other transit options in Durham mature with the passage of the half-cent sales tax increase in Tuesday’s election. Continued pressure to prioritize bike-friendly connections with new transit options will augment the success of the future transit system.

Future harmony of the various transit modes in using the shared-road resource will require acknowledgement on the parts of all road users.

Ultimately, the sharrows can only do so much to keep everyone aware and safe. It’s up to bikers to clearly communicate their intentions to drivers and those around them. All parties must follow the law and obey traffic signals. Also, wear a helmet when you’re on your bike. A bad hair day is worth another bad hair day!

For more discussion of bike related issues and to find more information, I encourage the bike community at Duke to visit http://www.bikeduke.com to keep track of news and information about bike commuting at Duke.

Brian will annoy you with his enthusiasm. He will irritate you with his optimism.

But, Brian is exactly the kind of person Duke needs to get this climate neutrality thing done.

Brian Williams (not the one from NBC), is the transportation demand management coordinator at Duke Parking and Transportation (DPT). He has only been on the job for a year, but he is making progress.

The 2009 Climate Action Plan (CAP) laid out the challenge.

According to the CAP, transportation accounts for approximately 23 percent of Duke’s baseline greenhouse gas (GHG) footprint. Commuters contribute about 52 percent, while air travel (43 percent) and the campus fleet (5 percent) make up the rest.

Brian’s focus is on alternative transportation. It’s his job to create the right incentives and implement programs that entice commuters and residential students to move from high impact modes of transportation (the single occupant vehicle (SOV)) to lower impact modes of transport like carpooling, vanpooling, public transit, bikes or walking.

This month’s Green Devil Challenge is on point in urging the Duke community to “Get Electrified” and to engage the latest batch of Brian’s alternative transportation options including WeCar, GoPass and the not yet arrived hybrid articulating busses which are slated to start service later this semester.

First, WeCar: WeCar is the new ZipCar-only-better (according to Brian) program run by Enterprise, and yes, they will come pick you up for extended rentals—on campus!

WeCar ratchets up the sex appeal of campus car-sharing programs with four Chevrolet Volts. These plug-in hybrid electric vehicles are touted to be the most fuel-efficient compact car sold in the U.S. They will travel approximately 35 miles (which is sufficient for most local trips) on a full charge before engaging the gasoline engine. Just remember to plug it in when you return—sharing is caring, after all!

An Enterprise representative who was checking up on the Volts, which reside just outside the Bryan Center, told me the usage on the vehicles has been good and steadily growing, as has membership in the WeCar program itself, which arrived on campus Aug. 15, 2011.

Although the program appears to be on track to duplicate and hopefully expand on the success of its predecessor, ZipCar, the reduction of SOVs and SOV trips on campus as a result of either program is unclear.

The second exciting edition to the alternative transportation arsenal is the new GoPass program. Replacing the old subsidized system, GoPass is essentially a free bus pass providing access to the regional transportation network (DATA , TTA, CAT and C-Tran) to students and those faculty and staff with offices on or adjacent to Duke’s Durham campus.

According to Brian, under the old program, approximately 600 to 700 people used public transportation and had a partially subsidized pass. Since the new GoPass program was announced, roughly 4,500 Dukies have claimed their GoPass—a plastic swipe card tied to your Duke unique ID. Of those new card holders, Brian reported that about 1,500 have used their card to access the public transit network at least once. However, more analysis of ridership patterns and improved usage rates will be required before the program can be called a true success. Regardless, the initial enthusiasm is impressive.

In addition to the new and modified programs, older programs, like the free Bull City Connector bus between Duke and Durham, carpool permits and the bike commuter program are also still available and building momentum.

Changes in culture can be difficult and can take a long time to manifest themselves. So when Brian reported that the number of carpool permit and bike commuter applications is much higher than last year and creating a backlog at the DPT offices, my first response was nearly an enthusiastic fist pump.

Unfortunately, I also know the flip side this backlog implies: it’s the frustration and confusion that comes from interacting with an over worked and stressed out DPT staff. Barriers get erected, communication breaks down, assumptions are made, progress is stunted, groups feel alienated … you get the idea.

So, we might all agree that good communication, clear information and useful resources are excellent, although non-trivial goals going forward now that a good foundation of alternative transportation options has been constructed. Good thing Brian is confident he can meet the challenge. In fact, he has already started with targeted in-person outreach, access maps for well served housing locations in Durham, maps of bike facilities on campus and informational how-to videos. And there’s so much more to come.

Lest you think I place too much faith in one man, I dare you to meet Brian. His infectious optimism for positive change will rub off and leaving you humming: “Always look on the bright side of life …”

See, we can all be like Brian.

Last week the City of Durham issued a press release announcing its recognition as a bicycle friendly community by the League of American Bicyclists. Durham was awarded a bronze-level recognition, the lowest of four levels recognized by LoAB. Chapel Hill also received a bronze-level recognition. Close by Carrboro bested both college towns, achieving a silver rating. Several other North Carolina cities also received awards.

This publication picked up on the story this week, and Tuesday’s edition of Towerview magazine had a one-page spread on just how hip the bicycle commuting trend is for the fall. In true magazine style, the short blurb was accompanied by a shopping list to aid interested trend-followers in getting in on the act.

I hope bicycling is more than a fall trend, but I also applaud all of the publicity this healthy and fun form of transportation is getting!

It’s been hot. Really hot. And humid.

No surprise there, really. This is the South, after all, albeit June.

Here in Durham, the mercury has been getting a workout, topping out at or above 90 degrees for most of the past two weeks.

Along with this increase in heat has come an increase in the AQI, or Air Quality Index. The AQI number ranges from 0-500 with a color code from green to maroon in six colors. The number and corresponding color is a daily measure that tells you how polluted your air is and what consequential health effects might be of concern.
