Advanced Traveler Information Systems (ATIS) communicate essential information about travel conditions to the public. ATIS devices include variable message signs, 511 telephone systems, highway advisory radio, and websites that collect, process, and disseminate information. Some state-of-the-art ATIS services deliver emails or text messages with traffic conditions to mobile devices upon subscription by user. These alerts are disseminated to static subscription lists not filtered based on the user’s travel history or real-time location. As a result, the user will receive many irrelevant mass alerts that are not relevant to their current location or immediate intended travel. It is likely that some users would be overwhelmed when their mobile devices are inundated by irrelevant travel information alerts and may eventually opt-out of subscription.
This proposal seeks to advance the state-of-the-art in ATIS by providing directed, personalized dynamic information to a traveler’s mobile device based on its exact location determined by Global Positioning Systems (GPS). The timeliness of this project is only heightened by the Federal Highway Administration (FHWA) notice of proposed rulemaking (NPRM) of January 14, 2009 (23 CFR Part 511) that proposes minimum parameters and requirements for States to make available and share traffic and travel conditions information via real-time information programs. It states that,
“Real-time information programs are proposed to be established so that States easily can exchange information on the real-time operational status of the transportation network with other States and with the private sector, value-added information market. This cooperation and sharing of information could stimulate the dissemination of traffic and travel conditions that include Web or wireless access to route-specific travel time and toll information; route planning assistance using historical records of congestion by time of day; and communications technologies that gather traffic and incident-related data from a sample of vehicles traveling on a roadway and then publishing that information to travelers via mobile phones, personal digital assistants (PDAs), in-car units, or dynamic message signs.”
A research study funded by the FDOT through the NCTR pioneered a travel behavior survey tool, referred to as TRAC-IT, which is software that can be installed on GPS-enabled mobile phones. Several components of TRAC-IT, including location-aware information system architecture and a Path Prediction prototype, can be employed to create an application that provides highly directed, real-time traffic alerts via mobile devices to the public. As part of the initial TRAC-IT project, a Path Prediction algorithm was developed and tested in a lab environment and successfully simulated the delivery of personalized real-time alerts to travelers based on their real-time GPS location and a set of sample traffic incident data. The algorithm is able to predict each user’s intended route and destination based on the user’s own historical travel data collected using the TRAC-IT mobile phone application, thereby reducing the number of irrelevant alerts provided to the user.
Building on information already collected for managing traffic and transit, this project proposes to expand the capabilities of the Path Prediction prototype to deliver personalized, route-pertinent incident information gathered by ATIS, including 511-based systems, to mobile phones. As part of this project, the Path Prediction algorithm will be enhanced, implemented, and tested in a real-world environment using actual GPS-enabled mobile phones and, if available, real-time data sources. After the user’s path is predicted, the algorithm can pinpoint incidents on and around the traveler’s route based on data from the 511 system and advise the user on detours or imminent delays as necessary.
Work not included in this scope of service is not to be performed and will not be subject to compensation by the Department.
Task 1: Project Management
Before any work begins, the research team will hold a kickoff meeting with the project team and the FDOT project manager. Researchers will advise the staff of the FDOT Research Center of meeting date and time and given the option to attend the meeting. The subject of the meeting will be to review and discuss the project’s tasks, schedule, milestones, deliverables, reporting requirements, and FDOT research deployment plan. This kickoff meeting will be conducted via teleconference or net conference. This task also will include on-going project management activities such as preparing progress reports and invoices, and reviewing and editing final deliverables.
Task 2: Conduct Literature Review and Identify Potential Data Sources
Collect and review ITS architecture for traveler information applications for all modes at the state and the metropolitan areas of Miami-Dade, Orlando, and Tampa Bay, APTA’s comprehensive Transit Communications Interface Profiles (TCIP) standards for mobile messaging, and other sources. This information will be used to develop a list of potential travel information services that can be personalized and timely-delivered to cell phones.
Identify current and planned real-time and archived travel information data source(s) in State of Florida, including sources used by 511 and local government traffic management centers.
Task 3: Modify TAD System to Facilitate System Updates and Deployment
- Based on Task 2, prepare criteria and anticipated tasks for project partner(s) who will give access to live real-time travel data and/or archived data that defines Application Programming Interfaces (APIs), etc. necessary for integration with TRAC-IT system
- Acknowledging the complicated process of obtaining a partnering community within the three months allocated to this task, we foresee the importance of FDOT in a leadership role in help securing the cooperation of a potential partnering community (e.g., 511 provider and local transit system in the same community). A stipend of $1,000 has been set aside to offset some of the time commitment likely incurred by the partner.
- Create Memorandum of Understanding (MOU) that will define required relationship between project team and partners
- Execute MOU with partner(s) and gain access to real-time travel data source(s)
Task 4: Develop Initial System Architecture of the Prototype for Selected Urban Area(s)
- Use the list of potential services, data sources and the partner identified in Task 3 to determine the dynamic information services to be developed under this project
- Examine partner’s system to determine available data and functions, compliance with standards, definitions of inputs and outputs, levels of access, APIs, database table structures, timeliness of data updates, etc. related to accessing and processing real-time data for the cell phone
- Develop initial prototype system architecture based on the partner’s system to link the service to be provided and the data sources available. The system architecture represents the conceptual design that defines the structure and behavior of a system, including the mapping of functionality onto hardware and software components.
Use the system architecture to prepare requirements and specifications for the system components for use by programming team.
Task 5: Develop prototype system software for the identified information services
- Acquire mobile phones and service that will support the TRAC-IT software client for GPS-enabled mobile phones
- Based on the information services identified in Task 4, develop and test software in support of these services (e.g., enhance the path prediction algorithm developed under TRAC-IT Phase 2 to take into account travel times of prior trips for issuing timely pre-trip alerts)
- Develop software, including communication protocols, to establish connection with real-time travel data sources identified in Task 4.
- Proceed with iterative development, test, and refining process for software on server and cell phone
- Conduct proof of concept field test for prototype with project team members
