Cooperative Transportation SystemsPooled Fund Study

  • The Pooled Fund Study (PFS) is a partnership of transportation agencies who have established a program to facilitate the development and evaluation of Connected Vehicle applications

  • The program will prepare state and local transportation agencies for the deployment of Connected Vehicle technologies

  • The program will result in the following outcomes:

    • Development and demonstration of Connected Vehicle-enabled system operations algorithms, tools and applications

    • Preparation for field demonstration tests

Enabling acceleration of a multi configurable on board equipment obe
Enabling Acceleration of aMulti-Configurable On-Board Equipment (OBE)

  • The successful deployment of Connected Vehicle applications will depend on widespread installation of OBE units in the vehicle fleet.

  • Over the last year, Visteon, completed a project that will prepare transportation agencies in selecting and procuring OBEs for fleet vehicles

  • The objectives of this project was to:

    • Identify Requirements of a Dynamic Configurable Multi-Band OBE

    • Analyze Current Market Readiness

    • Prepare Guidance Document to aid transportation agencies in procuring devices


Dynamic configurable multi band obe wireless technology evaluation
Dynamic Configurable Multi-Band OBEWireless Technology Evaluation

  • 5.9 GHz DSRC

  • Dedicated spectrum range for transportation, inexpensive

  • Provides high bandwidth and low latency in short range communications

  • Suitable for safety applications (V2V or V2I)

  • For time-critical, short-range (500m~1000m) safety applications

  • Cellular Communication (3G/4G/LTE)

  • Shared spectrum range, subscription based

  • Provides high bandwidth, long-distance communications with potentially high latency and packet loss with congested networks

  • Suitable for mobility, entertainment, large-file transfer, long-distance, and non-time critical safety applications

  • Wi-Fi

  • Widely available, inexpensive

  • Suitable for non-time critical, access point applications (e.g. hot spots, parked vehicle)

  • Bluetooth

  • For low-power, short-range (10m) and entertainment applications (e.g., music sharing, hands-free telephony)

  • Two-way Satellite and Bluetooth were evaluated but determined not to be suitable for connected vehicle applications


Dynamic configurable multi band obe wireless technology evaluation1
Dynamic Configurable Multi-Band OBEWireless Technology Evaluation

  • Transmission range

    • If the distance between the sender and receiver exceeds the DSRC transmission range, data can be transmitted and switched smoothly through 3G/3.5G interface

  • Inter-vehicle communications

    • A default communications interface can be set (e.g., DSRC for safety purpose) and switched to another interface dynamically (e.g., Wi-Fi for Internet access)


Dynamic configurable multi band obe hardware requirements
Dynamic Configurable Multi-Band OBEHardware Requirements

  • CPU requirements

    • For security applications, the OBE should utilize more powerful CPU (e.g., 1.6 GHz) due to high computing needs

    • For general purpose applications (e.g., electronic payment) the OBE CPU requirements can be less (e.g., 400 MHz)

  • Memory requirements

    • For GIS and digital map applications, the OBE should support large memory (e.g., 512 MB) to store and operate the geographically referenced data

  • Storage requirements

    • The OBE should support large storage space (e.g., 4 GB)

  • CAN Interface requirements

    • For safety applications, the OBE should connect to the CAN bus interface

  • GPS requirements

    • For time-critical and safety application, the OBE should support fast and accurate location information with its built-in WAAS (Wide Area Augmentation System) enabled GPS receiver

      • Accuracy: 5m with WAAS; 10m without WAAS


Dynamic configurable multi band obe procurement considerations
Dynamic Configurable Multi-Band OBEProcurement Considerations

  • Deployment Background

  • Geographic Area, operating environment, vehicle platform, etc.

    • Purpose of Deployment

  • Field test vs. commercial deployment

    • Operations Scenarios & Performance Testing

    • User Expectations

    • Understand market and industry status

  • Market status and offerings by vendors


  • Current market readiness analysis
    Current Market Readiness Analysis

    • There are multi-configurable OBEs currently on the market suitable for mobility and safety applications

    **Aftermarket Safety Devices being developed as part of the Safety Pilot Model Deployment in Michigan will include one or more optional non-DSRC radios of either 3G Wireless or WiMax. These devices will be available later this summer.


    Consumer research focus group interviews
    Consumer Research - Focus Group Interviews

    • Two focus group events were conducted

      • One focused on commercial vehicle drivers

      • The other focused on ordinary vehicle drivers

      • Consumers provided feedback on

      • OBE product attributes

      • Opinion on time-to-market for OBE features

      • OBE product pricing

      • Purchase/Service considerations of OBE product


    Consumer research result highlights
    Consumer Research – Result Highlights

    • Commercial vehicle drivers preferred safety featured applications

      • Collision warning systems, emergency braking, road maintenance, traffic signal violation, curve speed and redirection warning applications

    • Passenger vehicle preferred real-time traffic/travel information

      • Real-time traffic information, roadway condition weather, road maintenance, real-time traveler information, major events, and signal timing optimization applications

    • Drivers believe traffic management functions (e.g., corridor management, signal timing optimization, and ramp metering) should be public sector’s responsibility

    • Drivers believe the accident warning and driver information applications will be available sooner than traffic management applications

    • An on-board unit should cost an average of $200 but no more than $500

    • Commercial vehicle drivers would prefer to purchase aftermarket OBEs at repair shops, while passenger vehicle drivers prefer retail stores and dealerships


    Multi modal intelligent traffic signal system
    Multi-Modal Intelligent Traffic Signal System

    • Awarded to University of Arizona (March 2012 – March 2013)

      • Partly funded by the USDOT to support the Dynamic Mobility Application program

      • Develop a concept of operations, systems requirements and system design that services multiple modes of transportation

      • Prepare for field testing/demonstration of the developed Multi-Modal Intelligent Traffic Signal System at two locations

        • Maricopa County, Arizona

        • El Camino Real, California
