Multimodal traveler information systems facilitate informational connectivity by integrating information on transit modes with information on driving or intercity bus/rail transportation options. To seed the development of these systems in the U.S., the Federal Transit Administration (FTA) and the Northeastern Illinois Regional Transportation Authority (RTA) executed a cooperative agreement in March 2005 for a national demonstration of a web-based Multi-Modal Trip Planning System (MMTPS).

The MMTPS concept envisions a system that:
  • Provides door-to-door travel options with transit treated as a single system regardless of how many separate agencies provide service for a given trip
  • Includes at least transit, driving, walking (e.g., walking to transit), and multimodal travel (e.g., driving to transit) as options, but may also include options for bicycling, carpooling, intercity bus/rail transportation, or other modes
  • Includes parking information where applicable
  • Incorporates accessibility information and features of the transportation network (e.g., street types, pedestrian signals, curb cuts, accessible transit locations) and accommodates customer preferences and constraints (e.g., minimum walking distance, fastest trip, rail only, accessible features and locations)
  • Uses historical or real-time data/information on travel times to enable travel choices throughout the metropolitan region based on typical or real-time transit and driving travel conditions:
  • Uses historical or real-time driving data/information to recommend a route for an auto trip and to compute the estimated travel time
  • Uses schedule travel time data on transit routes to compute the estimated travel time for a transit trip; incorporates real-time information on transit incidents and delays, and provides alerts of these incidents and delays and/or uses this information in the recommendation of routes and estimation of travel times
  • Includes travel costs for all modes included in the trip planner, including parking costs (if applicable)
  • Is integrated with existing systems using Intelligent Transportation Systems (ITS) standards implemented in XML
  • Is Section 508 compliant
  • Maintains or reduces operating costs per passenger mile and offsets other costs, such as call center or e-mail responses
  • Facilitates increases in transit ridership

The objectives of the operational demonstration are to:
  1. Develop a door-to-door multimodal trip planner that incrementally achieves the vision (in full or in part) as described above
  2. Evaluate use of the trip planner to gain a better understanding of the design and marketing necessary to achieve the vision
  3. Identify technical and institutional hurdles and possible solutions to achieve the vision
  4. Evaluate the benefits and impacts of the system

Through this demonstration with the RTA, the FTA seeks to replicate MMTPS in other regions.

Mr. Gerwin Tumbali is the Manager of Engineering & Technology in the RTA's Planning Department. He directs the RTA's Regional Transit Intelligent Transportation Systems (ITS) Program involving the planning, execution, and evaluation of the RTA's transit technology projects and associated activities.

Mr. Tumbali is a Project Management Professional (PMP©) with over 13 years experience in project and program leadership. Prior to joining the RTA in March 2000, he was a Project Manager for ARCADIS, n.v., a global infrastructure and environmental engineering firm.

Gerry received his Master in Business Administration from the Keller Graduate School of Management and his Bachelors of Science in Mechanical Engineering from the University of Illinois - Chicago.
