Goals and Objectives of the Study
9
Goals of the Study
  • Facilitate concept development and needs refinement for IDTO applications
  • Assess relevant prior and ongoing research
  • Develop functional requirements and corresponding performance requirements
  • Develop high-level data and communication needs
  • Assess readiness for development and testing


10
Goals of IDTO
  • Examine what technologies can help people effortlessly transfer from one mode of travel (car, bus, train, etc.) to another for the fastest and most environmentally friendly trip
  • Seek to make cross-modal travel truly possible
  • Enable agencies and companies to manage their systems in light of the fact that people may be changing modes often
11
IDTO Applications Definitions
  • Connection Protection (T-CONNECT) - enable public transportation providers and travelers to communicate to improve the probability of successful transit transfers.  This application would potentially include intermodal and interagency coordination.


  • Dynamic Transit Operations (T-DISP) - links available transportation service resources with travelers through dynamic transit vehicle scheduling, dispatching and routing capabilities.  It would also enable travelers to make real-time trip requests through personal mobile devices.


  • Dynamic Ridesharing (D-RIDE) - makes use of in-vehicle (drivers) and hand-held devices (riders) to dynamically identify and accept potential ridesharing opportunities along the travel route.
12
T-CONNECT Example
13
T-CONNECT: State of the Practice
  • T-Connect addresses problem of multiple transfers between different transit modes by enabling communications to improve probability of a transfer


  • Exists mostly for bus-to-bus transfers, but limited application of for rail-to-bus


  • Relies on passenger request to driver


  • No US examples of regional, multiple operator connection protection
14
T-DISP Example
15
T-DISP: State of the Practice
  • T-DISP addresses variety of transit services offered in certain conditions and allows travelers to assess their travel options


  • Dynamic transit services operated in numerous locations around the US, but very few employ technology.  Use of technology more prevalent in European dynamic transit operations


  • Orlando’s Lynx FlexBus and United We Ride/Mobility Services for All Americans projects will provide valuable information
16
D-RIDE Example
17
D-RIDE:  State of the Practice
  • D-RIDE promotes ridesharing through in-vehicle and handheld technologies, and improvements to information available for high occupancy vehicle/toll lanes


  • Various forms of ridesharing since early 1990s, but now new “products” available using current technology


  • Input from Ridesharing Institute (created 2011) and new ridesharing products critical to understand marketplace


  • Limited toll lane and in-vehicle functionality


18
Investigate Answers to Questions
  • Do current practices take full advantage of new transit technologies, tools and data sources?
  • What emerging opportunities exist for the new generation of automated tools to be used to facilitate the deployment of the IDTO applications?
  • Is there strong motivation for a federal role in facilitating the development of new technologies and tools to capitalize on these identified opportunities?
19
Summary of Findings from Scan of Current Practice
20
Findings: Literature Review
  • Academia
  • USDOT Programs
  • United We Ride/Mobility Services for All Americans (UWR/MSAA)
  • Connected Vehicle Program
  • Dynamic Mobility Applications
  • Research conducted by TRB and other associations
21
T-CONNECT Current Practice
22
T-CONNECT Current Practice (cont’d)
  • Several examples in fixed-route implementations.  Commonplace with many CAD/AVL systems
  • For example, UTA’s TCP deployment between TRAX light rail and fixed-route buses
  • For example, commuter rail to fixed-route bus in Brampton, Ontario
  • No evidence of direct T-CONNECT implementation, but commuter rail often provides “unconditional” transfers


23
T-CONNECT General Findings
  • Literature limited
  • Evaluation of UTA TCP program revealed that program well-regarded
  • Fixed-route to Fixed-route TCP is only T-CONNECT-type implementation that exists today in the US


24
T-CONNECT Challenges
  • Electronic information exchange necessary, but important to ensure consistency of coordination on business processes related to transfers
  • After-the-fact review of transfer trips should be conducted
  • “Maximum allowed” waiting time should be defined
  • Definition of TCP should be by route, not by vehicle
  • Manual intervention should be allowed
  • Accuracy of real-time vehicle locations must be ensured
25
T-DISP Current Practice
  • Application limited in US:
    • Flexibly-routed service with technology limited
    • No one site with all T-DISP elements: coordination of transportation services, transit technology, technology to provide information to travelers and travel management coordination center
  • Existing programs with some elements:
    • UWR/MSAA initiative
    • FlexBus in Orlando, FL
    • North and East Brainerd routes in Chattanooga
    • Belbus in Belgium and Flexlinjen in Sweden

26
T-DISP General Findings
  • Service coordination challenges are complex
  • Technology alone will not overcome coordination barriers
  • Limited demonstration of technology application and coordination together
  • Travelers and their needs, particularly information, critical part of T-DISP concept
  • Few states that include transit in 511 systems


27
T-DISP Challenges
  • Difficulty in coordinating amount multiple transit agencies, funding programs, and local, state and Federal entities
  • Lack of effective coordination structures has contributed to:
    • Service area gaps
    • Limited services
    • Confusing and low quality customer service
  • Limited deployment of real-time transit information systems
28
D-RIDE Current Practice
  • Pilot in Santa Barbara County through FHWA Value Pricing Pilot Program
  • FHWA-sponsored scan of casual carpooling/ slugging phenomenon
  • Project in San Diego to sync software with in-vehicle computer, and calculate number of passengers
  • Rideshare pilot in Washington State SR 520 corridor
  • Multiple private companies/programs
29
D-RIDE General Findings
  • Wide range of technologies employed, and with more mobile and internet-based technologies
  • Fear of strangers often cited as reason for not sharing rides, so focus on making participants more comfortable
  • Providing familiar meeting points and drop-off locations in addition to users’ homes way to make participants more comfortable
  • Marketing necessary to draw initial crowd
  • Incentives can draw more users


30
D-RIDE Challenges
  • Implementing controls to minimize safety concerns regarding sharing a vehicle with a stranger
  • Lack of established rideshare infrastructure (meeting points and drop-off locations)

    • Ridematch is requested by the driver through an in-vehicle application system using DSRC or wireless mobile technology.
    • D-RIDE Data Center is capable of processing various types of data sent through the ridematching applications and can also process payment.
    • D-RIDE Data Center is capable of interfacing with traffic data center’s traffic data for the routes being requested by the travelers.
  • Description of elements:
    • Traveler: Both the passenger requesting a ride as well as the traveler accepting passengers
    • Passenger: Traveler in need of a ride
    • Driver: Traveler in need of passengers
    • D-RIDE Data Center: Processes ridematch requests from requestor route and location data
    • Traffic Data Center: May also be a TMC; provides traffic data



108
Scenario 1- Data Flows
  • Travelers enter trip information into D-RIDE interface system via mobile device (passenger) or in-vehicle system (driver) through wifi, DSRC, or mobile network to D-RIDE data center OR  traveler enters trip information into D-RIDE interface system via internet.
    • Information includes: trip plan request, origin and destination (OD) data, traveler profile and preferences, and traffic data (from a traffic data center)
  • The center accepts requests from traveler interface systems for ridesharing as part of a trip plan request. The center processes the requests by balancing the relative benefits of the rideshare to each rideshare participant.
  • The center provides a rideshare match based on data from the travelers proposed trips, any routing constraints, preferences specified by the traveler, compatibility of this rideshare with other travelers, eligibility data, and traffic data. This match is reported back to the travelers.
  • The travelers confirm the rideshare match and the confirmation is sent back to the center.
  • The center stores all rideshare matches and traveler eligibility data and sends a message back to the travelers that their ridematch has been accepted. The center also supports payment transactions for the service.




109
Scenario 2 – Multi-Leg, Multi-Modal Request
110
Scenario 2- Assumptions and Elements
  • Assumptions:
    • Ridematch is requested by the passenger using a personal hand-held device application or an internet form.
    • Ridematch is requested by the driver through an in-vehicle application system using DSRC or wireless mobile technology.
    • D-RIDE Data Center is capable of processing various types of data sent through the ridematching applications and can also process payment.
    • D-RIDE Data Center is capable of interfacing with traffic data center’s traffic data for the routes being requested by the travelers.
    • T-DISP Control Center is equipped with scheduling, CAD/AVL, traffic, and messaging systems that allow for transit trips and/or private modes to be scheduled.
    • In this scenario, the D-RIDE Data Center and the T-DISP Control Center are separate entities that can communicate with one another. *An alternative scenario would be that the D-RIDE or T-DISP application could function as one combined control center (not displayed in this scenario).*
  • Description of elements:

    • Private Mode: Includes taxi, shuttle, and volunteer services
111
Scenario 2- Data Flows
  • Travelers enter trip information into D-RIDE interface system via mobile device (passenger) or in-vehicle system (driver) through wifi, DSRC, or mobile network to D-RIDE data center OR  traveler enters trip information into D-RIDE interface system via internet.
    • Information includes: trip plan request, origin and destination (OD) data, traveler profile and preferences, and traffic data (from a traffic data center)
  • The center accepts requests from traveler interface systems for ridesharing as part of a trip plan request. The center processes the requests by balancing the relative benefits of the rideshare to each rideshare participant.
  • Using traffic data and route optimization, the center picks up that an incident is causing major delays along the passenger’s route and that transit or other private mode (taxi, shuttle) may be the best fastest option to their destination. The center sends a message to the passenger asking if they would like to add a transit leg to their trip.




112
Scenario 2- Data Flows (Cont.)
  • The passenger accepts the addition of the transit leg to their trip. This message is sent to the T-DISP Control Center via internet or wifi/DSRC/mobile network.
  • The T-DISP Control Center utilizes scheduling, CAD/AVL, and messaging systems to schedule a transit or private mode trip. The selected trip is sent to the D-RIDE Data Center to add as part of the overall ridematch output.
  • The center provides a combined driver + transit rideshare match based on data from the travelers proposed trips, any routing constraints, preferences specified by the traveler, compatibility of this rideshare with other travelers, eligibility data, and traffic data. This combined driver + transit rideshare match is reported back to the travelers and accepting transit
  • The travelers confirm the rideshare match and the confirmation is sent back to the center.
  • The center stores all rideshare matches and traveler eligibility data and sends a message back to the travelers that their ridematch has been accepted. The center also supports payment transactions for the service.


113
Scenario 3 –HOV/HOT Lane Enforcement and Tolling
  • Description: In this scenario, the georeferencing mechanism of the D-RIDE application and devices allows the D-RIDE data center to process the location of travelers (in vehicle and in a high-occupancy lane) in order to process HOV/HOT Lane violation citations and appropriate tolling charges.
114
Scenario 3 –HOV/HOT Lane Enforcement and Tolling
115
Scenario 3- Assumptions and Elements
  • Assumptions:
    • D-RIDE applications on both the device and in-vehicle systems are capable of constantly sending location-based information associated with a unique identifier code for each user.
    • D-RIDE Data Center is capable of processing constant flows of information from travelers in motion.
    • D-RIDE Data Center is outfitted with georeferencing to know where HOV/HOT lanes are located and whether or not travelers are riding in the lane.

    • Traveler: Both the passenger requesting a ride as well as the traveler accepting passengers
    • D-RIDE Data Center: Processes ridematch requests and requestor route and location data
    • Tolling and Enforcement Center: issues citations for violations and processes e-tolling payments
116
Scenario 3- Data Flows - Enforcement
  • Travelers that have been ridematched turn on their D-RIDE applications (devices and in-vehicle) while en route.
  • The travelers enter into an HOV 2+ lane with their D-RIDE applications still on. These applications emit a unique identifier code that is linked to individual passengers and the driver. This code is sent to the D-RIDE Data Center to process to location of the previously matched travelers which the system recognizes as paired.
  • Using GPS location information from the travelers’ D-RIDE applications, the center recognizes that the travelers have entered an HOV 3+ zone. With only 2 travelers known to the center to be in the ridematch, the center sends a message to the traffic tolling and enforcement center.
  • The Tolling and Enforcement Center sends a citation to the driver’s home using the traveler profile information sent with the violation message from the D-RIDE Data Center.


117
Scenario 3- Data Flows – Tolling
  • Travelers that have been ridematched turn on their D-RIDE applications (devices and in-vehicle) while en route.
  • The travelers enter into an HOT 2+ lane with their D-RIDE applications still on. These applications emit a unique identifier code that is linked to individual passengers and the driver. This code is sent to the D-RIDE Data Center to process to location of the previously matched travelers which the system recognizes as paired.
  • Using GPS location information from the travelers’ D-RIDE applications, the center recognizes that the travelers have entered an HOT 2+ zone. Recognizing the two travelers in the ridematch en route on the HOT @+ lane, the center sends a message to the Tolling and Enforcement Center that the vehicle can be charged $3.25.
  • The Tolling and Enforcement Center process the message and deducts $3.25 from the driver’s account through the driver’s e-tolling pass registered as part of their traveler profile information sent by the D-RIDE Data Center.
