Integrating Bicycles into Intermodal Transport
Integrating Bicycles into Public Transportation Facilities
By Scott Silsdorf, Boston, Massachusetts, 1-617-960-4932, silsdorf@pbworld.com

Many changes have been made in the U.S. over the past ten years to make bicycle riding a successful component of intermodal transportation. These changes and the need for further coordination present numerous opportunities for planners and engineers.

Bicycle "Skillet" Heats Up


A group of staff members has been working diligently during the past year to establish a system to share resources and experiences in bicycle planning and design. Led by Steve Plano in the Baltimore, Maryland office, the group calls itself the PB "Bicycle Skillet"(a small PAN, or practice area network), based on its status as a subgroup of PAN 45, Surface Transport Planning.

The idea of the skillet developed over the past few years as more and more of our staff sought input and guidance for bicycle projects (or bicycle elements of larger, intermodal transportation planning projects). No single source of bicycle information was readily available, but informal contacts among staff led to discussions regarding current and future project opportunities. With bicycling (along with other non-motorized transportation modes) continuing to receive significant public attention and funding in the U.S., it became apparent that we needed a more organized group to share and promote bicycle-planning resources, so PAN 45 created the Bicycle Skillet.

Skillet members post relevant bicycle information in MS Outlook public folders in a subfolder of the Surface Transport Planning PAN. We will establish further subfolders as needed for areas such as project information, proposals, qualifications, resumes, documents, resources and graphics (see All Public Folders/Practice Area Networks/Surface Transport Planning/Bicycle "Skillet.") In addition, the group is in the process of establishing a site on the PB intranet.

Although focused originally on U.S. projects, the skillet wants to also incorporate the talents and design experiences of our entire network of professionals, so the group has sent requests for bicycle-planning material to staff worldwide. We are working to assemble updated summaries of the company's bicycle projects and qualifications, and we would appreciate your assistance and input to help us become a technical resource center within PB. If you have bicycle-planning materials to share with other offices, please see the "read me"document posted at the Bicycle Skillet directory for instructions on posting your information in the Bicycle Skillet subfolders.

Successful passenger-oriented intermodal transportation facilities enable easy transfers between various travel modes, such as from commuter rail to rail transit, bus to light rail, and rail transit to airport terminals. Logical intermodal connections that have been overlooked frequently include those possible between bicycles and public transportation. During the past ten years, however, a combination of a resurgence in transit ridership in the U.S. and an increase in federal funding for bicycle facilities has lead to new opportunities for accommodating bicycles with intermodal passenger facilities.

Careful design of bicycle accommodations should:

  • Provide intermodal connections that are safe and convenient

  • Provide secure bicycle storage areas

  • Provide bicycle-oriented amenities to either attract new bicycle riders or better serve existing ones

  • Result in increasing numbers of transit riders

  • Reduce the need for space-consuming automobile parking facilities

  • Help to meet the goal established by the U.S. Department of Transportation in 1994 to double the percentage of all trips made by bicycle.

The focus of this article is twofold the status of bicycle intermodal connections with bus and rail public transportation providers, and some issues for planners and engineers to consider when responding to the challenges and opportunities presented by integrating bicycle facilities with new or existing transit facilities.

Overview of Current Status

Integrating bicycles with public transportation is not a new concept, as Figure 1 illustrates. A large part of the current momentum in the U.S. has occurred over the past ten years, however, with the addition of racks on buses and an increasing accommodation of bicycles on rail transit vehicles marking the most dramatic changes. According to the informational Web site, http://www.bikemap.com, bicyclists now have access to more than 350 public transportation providers, including 239 local bus systems with bicycle racks, 27 rapid transit systems (light rail or heavy rail), 15 commuter rail systems, 11 intercity bus lines, 26 ferry systems, 12 Amtrak routes and 6 scenic rail lines.

Bicycle Accommodations on Buses. A rack mounted to the front of a vehicle is the primary means of accommodating bicycles on buses and rideshare vans. Bicycles can be mounted easily by the bicyclists, and each rack typically accommodates two bicycles. Some transit agencies allow bicycles inside their buses (when accompanied by the bicyclists) if the existing rack is full or the bus is not fitted with a rack. This accommodation is often subject to restrictions if the bus is full, however, such as during peak periods.

According to the League of American Bicyclists, in 1993 only one transit agency provided bicycle racks on buses. Today, an estimated 30,000 bicycle racks are in use across the country and an estimated 500,000 bus riders combine bicycling with transit. Many large cities, such as Seattle, Washington and San Diego, California, have outfitted their entire bus fleets with bicycle racks. Seattle Metro's transit buses carry 60,000 bicyclists per month. The FTA estimates that bicycles are currently accommodated on 20 percent of all local transit buses nationwide.


Bicycle Accommodations on Rail Transit.
Accommodations for bicycles vary among agencies and depend on numerous conditions, such as load factors and vehicle types. Many light rail, commuter rail and heavy rail transit agencies allow bicyclists to bring their bicycles aboard trains during non-peak periods or with special permits and, typically, stand with their bikes in an areas of the trains that are not crowded.

New York City Subways. In New York City, bicycles are permitted aboard subway rail cars during all periods, subject to specific conditions.

Caltrain. Caltrain, the 113-k (70-mile) long commuter rail line that serves San Francisco and the Silicon Valley in California, is a leader in bicycle accommodations. Its provisions have expanded from an initial capacity of four bicycles per train in 1992 to a minimum of 24 bicycles in the forward car of every train. (A few trains carry two bicycle cars, for a maximum of 48 bicycles per train.) Caltrain carries approximately 2,000 bicyclists each day.

The success of Caltrain's on-board bicycle accommodations has led to a pilot program to introduce a "two for the price of one" bicycle locker rental fee. The concept assumes that if a bicyclist is provided space for a bicycle at both the beginning and ending station of the rail commute, fewer will bring their bikes onboard.

Valley Transit Authority (VTA). VTA operates a light rail transit (LRT) system in San Jose and Santa Clara Counties that connects with the Caltrain system at two stations. In 1994, VTA modified each LRT car to accommodate bicycles by removing two middle seats and installing racks that accommodate four bicycles. When standing room permits, two additional bicycles may be brought into the center of the vehicle. Each three-car VTA light rail train now has the capacity to carry 18 bicycles.

Amtrak Intercity Train. Amtrak's standard policy has been to have bicycles disassembled and packaged in boxes (similar to airline travel). Now, however, Amtrak is increasing the number of trains with "roll-on access"--providing bicycle racks aboard such trains as the "Cascades" route in the Pacific Northwest (six bikes per train, advance reservations required), and the "Capital Corridor" route in northern California (three bikes per California car).

On the East Coast, Amtrak recently announced a "Bikes on Board" plan and marketing agreement with the East Coast Greenway Alliance (ECGA), a non-profit organization working to develop a shared-use path from Maine to Florida. Bicycle racks are currently available on four East Coast routes in trains with baggage cars, the "Twilight Shoreliner," "Vermonter," "Ethan Allen Express" and the "Adirondack."

Funding Improvements

Much of the activity in increasing bicycle intermodal connections has been fostered by major improvements in the funding of such projects. Before passage of the Intermodal Surface Transportation Efficiency Act (ISTEA) and its successor legislation, the Transportation Equity Act for the 21st Century (TEA-21), most bicycle funding in the U.S. was limited to state and local programs. Funding for pedestrian and bicycle improvements has grown from $6 million in 1990 to over $238 million in 1997.

By 1999, it was possible to apply almost all transportation funding programs to making improvements for bicycling, according to a DOT study published in April of that year entitled "National Bicycling and Walking Study: Five Year Status Report. "These programs, which include funds from both the Federal Transit Administration (FTA) and the Federal Highway Administration (FHWA), include the Congestion Mitigation and Air Quality (CMAQ) Program, Transportation Enhancements Program, the Surface Transportation Program and the National Highway System. Under TEA-21, the FTA will fund 95 percent of the cost to link bicycles with transit when using federal transit enhancement grants, and other federal transit funding programs match 90 percent.

Challenges to Further Integration

Despite the large increase in bicycle intermodal connections during recent years, we face numerous challenges to further integration. Some of the issues we need to consider are highlighted below.

Peak Period Accommodation. Large transit systems, such as those in Boston, Massachusetts; Chicago, Illinois; and Philadelphia, Pennsylvania; operate with peak-period load factors that make accommodating bicycles on board transit vehicles nearly impossible. Yet, as accommodation of bicycles grows on other systems with lower ridership, public expectations for development of bicycle/public transit commuting options are increasing. When improving bicycle accommodations aboard transit vehicles is not possible, other enhancements, such as better accommodations at stations, will become essential to further integrating bicycles with transit systems nationwide.

System Integration. Across the country and around the world, public transportation systems are becoming more intermodal as new systems and system expansions connect to existing services. New light rail transit systems are linking with local bus systems and other rail transit systems. At Hoboken Terminal, New Jersey's Hudson-Bergen Light Rail line will provide direct connections to both NJ Transit commuter rail and Port Authority Trans Hudson (PATH) trains, further linking New Jersey and Manhattan. In Boston, preliminary engineering is underway to extend Massachusetts Bay Transportation Authority's (MBTA)'s commuter rail service (currently serving eastern Massachusetts and running south to Providence, Rhode Island) to Nashua, New Hampshire. With these extensions come new system integration challenges. Bicyclists, like other transit customers, prefer consistent policies and operating standards regardless of which jurisdiction or agency is providing a transit service. Providing this consistency in an environment with multiple operators and public transit modes may be the next hurdle to greater integration of bicycles and public transit.

System Compatibility. Even transit systems operated by a single authority suffer difficulties with system-wide bicycle integration. In Boston, for example, due to capacity constraints and access issues, the MBTA's green line prohibits bicycles at all times, but permits them on all other MBTA rail lines during weekends and off-peak conditions. In addition, bicyclists are prohibited from entering or exiting four transit stations in downtown Boston due to safety and congestion concerns.

These types of problems are generally restricted to older transit systems, and finding solutions is a challenge for "comeback cities" such as New York, Philadelphia, Boston and Chicago. As older stations in these cities are modernized, bicycle access improvements should also be considered in order to improve compatibility throughout the transit system.

Jurisdictional Issues. Local governments are usually responsible for designating and providing bicycle routes and making on-street improvements that accommodate bicyclists -features that are critical to bicyclists' access to public transit. For bicycle intermodal connections to continue to evolve, local governments will need to work with public transit providers to improve bicycle access and work toward developing a coordinated system of bicycle routes. Cooperation and communication between agencies will be required if we are to see significant improvements.

Excessive Administration. One challenge to transit systems' expanding bicycle access is the administrative burden of the new programs and services. To stem the problem of escalating administration of bicycle programs, many transit systems have recently stopped requiring bicyclists to carry permits in order to bring bicycles on transit vehicles. These include Boston's MBTA, New Jersey Transit, Washington D.C.'s Metrorail and the San Diego Trolley.

Recommendations - What PB Can Do

Safety and Liability. Bringing bicycles aboard vehicles and into station areas, stairwells and train platforms can raise safety issues. To reduce safety risks, most agencies have strict minimum-age requirements for bicyclists and restrict bicycles from being ridden in the station areas. Bicyclists are often required to allow "regular" passengers to enter or exit transit vehicles first. In vehicles where bicycles may be stored in unoccupied seating areas, cyclists must give up their space to any disabled passengers who need seats. Despite these and many other safety and compatibility policies, the presence of bicycles aboard transit vehicles can lead to liability issues. Potential legal issues should be researched for any new bicycle accommodations

In many of our projects, we planners and engineers may be asked to incorporate bicycle accommodations into transportation facilities or to provide operational or management consultation to transit agencies operating new or existing transit services. By considering the following simple recommendations, we can lead in the development of bicycle accommodations with public transportation facilities.

Stay Informed. A primary purpose of this article is to highlight current activities related to bicycle integration with public transportation. Our staff should remain aware and informed about bicycle planning and design issues. To help meet this requirement, the PB Bicycle Skillet has been formed to foster the sharing of challenges and successes with regard to bicycle projects (see sidebar).

Assess the Current Situation. When beginning a project that may include the opportunity for enhancing bicycling connections with public transportation, assess the status of bicycle usage in the area or on the system and determine what the opportunities are for integration. If the opportunities are low, decide why. Is it a policy issue, a design constraint or an access issue that would preclude increased bicycle use in the facility? Also, find out if another agency or local jurisdiction is doing something that might change the situation. For example, is a city or county bicycle plan being formulated that may address improving access to pubic transportation?

Involve Local Bicyclists. Public involvement activities should seek input from bicycle users and groups in the project area. Projects that receive input are more likely to be successful than projects planned or designed with no input from potential users. Use project mailings to target local clubs, and look for opportunities to include bicyclists on project advisory committees.
Related Web sites

The following Web sites provide additional information on integrating bicycles into public transportation facilities:

Consider Bicycle Access when Choosing New Station Locations. Automobile access is almost always used as a station site selection criterion. Bicycle access should also be considered. Often, bicyclists will access the station area using the same route as automobiles; however, there may be an opportunity to provide direct linkages to existing or planned trails or other bicycle routes in the station area. In either case, review surrounding streets for their bicycle accommodations using either a qualitative method or a quantitative method, such as the bicycle level of service (BLOS) assessment.

Plan and Design for Bicycle Access. Station designs should capitalize on the surrounding bicycle network. New rail transit stations, particularly in suburban environments, have opportunities for accommodating bicycles in the design of streets and parking areas. Station accommodation should consider bicycle signage, bicycle lanes or exclusive-use trails to connect local streets to station areas. When new traffic signals are installed to control vehicle access to stations, consider adding bicycle loop detectors for signal actuation.

Provide Adequate Parking Accommodations. Offering safe and secure bicycle-parking facilities is one of the simplest ways to combine bicycling with public transit. (See also "Introduction to Bicycle Parking," by Shawn Dikes.) The passengers who are most willing to bicycle to a transit station are typically capable of riding in mixed traffic and desire a safe place to store their bicycles at the station.

Consider Other Amenities. Providing bicycle-amenities at transit stations may help increase the use of bicycles in transit access trips. Bicycle "stations" introduced in California cities, such as Long Beach, Palo Alto and Berkeley, provide various amenities that include valet parking for bicycles, repair services, rentals, restrooms and changing rooms.

Specify Bicycle Access on New Transit Vehicles. If a transit project involves creating vehicle specifications, consider incorporating bicycle racks. Many of the transit vehicle bicycle racks in use in the U.S. today represent "first generation" attempts at accommodations. As new vehicles are procured, there are opportunities to improve bicycle access while still meeting seating and regular accommodations.

We must integrate multiple modes to improve the transportation system for all travelers if we are to play a meaningful role in solving public transportation problems effectively. In many communities, bicycle travel has become an important part of the public transportation infrastructure, yet there is potential for much better accommodation. By understanding current issues and following the recommendations listed above, planners and engineers can facilitate further integration of bicycles into existing and new public transportation facilities.
