The Connected Vehicle Safety Pilot Program is part of a major scientific research program run jointly by the U.S. Department of Transportation (DOT) and its research and development partners in private industry. The Connected Vehicle Safety Research Program supports the development of safety applications based on vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications systems, using dedicated short-range communications (DSRC) technology.

The Safety Pilot is designed to determine the effectiveness of these safety applications at reducing crashes and to show how real-world drivers will respond to these safety applications in their vehicles. The test will include many vehicles with vehicle awareness devices, others with integrated safety systems, and others that use aftermarket safety devices to communicate with surrounding vehicles. All of these technologies are based on DSRC technology. The Safety Pilot will include multiple vehicle types—cars, trucks, and transit vehicles.

The driver clinics began in August 2011 and will continue through early 2012; the model deployment will run from the fall of 2012 to the fall of 2013

The vision for the Connected Vehicle Safety Pilot Program is to provide the world with a model deployment that demonstrates the transformative nature and benefits of connected vehicle technologies for safety and that can be further extended to support non-safety needs relating to mobility and environmental impacts. In the past, the U.S. DOT has focused on helping people survive crashes. Connected vehicle safety will change the paradigm by helping people avoid crashes.

Research Goals

The goals of the Safety Pilot are three-fold:

  • To test the effectiveness of wireless connected vehicle technology in real-world, multimodal driving conditions
  • To collect data about how ordinary drivers adapt to the use of connected vehicle technology
  • To identify the potential safety benefits of connected vehicle technology.

The Safety Pilot program includes two critical test efforts—the Safety Pilot Driver Clinics and the Safety Pilot Model Deployment.

Safety Pilot Driver Clinics

In August 2011, the Safety Pilot Driver Clinics began to test the new V2V safety applications with ordinary drivers in controlled roadway situations. The evaluations explore driver reactions to safety applications using a variety of light-duty vehicles (cars) and under a variety of test conditions. Everyday motorists participate in the driver clinics in controlled environments such as test tracks and parking facilities. These clinics are being conducted at six sites geographically dispersed throughout the United States. Separate driver clinics will be conducted for trucks.

The driver clinics are an important first step in identifying how drivers respond to new innovative wireless devices for safety. One measure will be to determine whether the new applications create any unnecessary distractions for motorists, which may result in additional crashes. To assess drivers’ response to and benefits from in-vehicle alerts and warnings, approximately 100 everyday drivers are testing the technologies at each driver clinic.

The driver clinics began in August 2011 and will continue through early 2012.

Safety Pilot Model Deployment

To continue the data collection under real-world conditions, a test site with multimodal traffic will be selected to host approximately 3,000 vehicles equipped with V2V devices. The goal is to create a highly concentrated connected vehicle communications environment with vehicles “talking to each other.” The devices to be tested include embedded, aftermarket, and a “simple” communications beacon (see the FAQs below for details on the various devices). All of these devices emit a basic safety message 10 times per second, which forms the basic data stream that other in-vehicle devices use to determine when a potential conflict exists. When this data is further combined with the vehicle’s own data, it creates a highly accurate data set that is the foundation for cooperative, crash avoidance safety applications. Using a mix of cars, trucks, and transit vehicles, the Safety Pilot Model Deployment will create test data sets for determining the technologies’ effectiveness at reducing crashes. These capabilities will also be extended to a limited set of V2I applications. Supported by a diverse team of industry, public agencies, and academia, the model deployment will run from the fall of 2012 to the fall of 2013.


The preliminary results of the Safety Pilot Driver Clinics are in. Findings show that drivers across age groups and gender desire vehicle-to-vehicle (V2V) technology. Conducted from August 2011 to January 2012, each driver clinic had over 100 drivers testing in-vehicle wireless technology.

The V2V safety applications tested included emergency brake-light warning, forward-collision warning, intersection movement assist, blind-spot and lane-change warning, do-not-pass warning, and left-turn assist. Over 90 percent of the respondents indicated that they would like to have the V2V safety features in their vehicles, with the intersection-movement-assist application rated the highest in desirability (93.9 percent), usefulness (95.5 percent), and intuitiveness (92.8 percent). However, all of the safety features received a positive response in all three areas.

In terms of the unintended consequences of the safety features, 74.5 percent of the drivers felt that the safety features would not be any more distracting to their driving than using the car radio. Most participants were either neutral or disagreed that the safety features would cause drivers to pay less attention to their driving environment. The majority of the participants felt that the market would need to be at least 70-percent saturated with equipped vehicles to notice any benefits, and the majority of respondents (58 percent) would be willing to pay up to $250 for the V2V technology. Overall, respondents felt the benefits of connected vehicle technology (saving lives and preventing accidents) far outweigh the potential drawbacks (dependency, complacency, or over-reliance).

Applications and equipment

Applications tested

  • Embedded Devices: Installed during the manufacturing process, these devices integrate directly with the vehicle’s computers, thus providing the ability to draw on a wide range of data. In addition to emitting and receiving the basic safety message, vehicles with embedded devices can further communicate data on speed, acceleration and deceleration, yaw rate, turning, wiper activity, and braking, among others. Cooperative, crash avoidance safety applications rely on this enhanced data stream to provide highly accurate, real-time alerts, advisories, and warnings to the driver. In the case of buses, trucks, and motor coaches, these devices are integrated after production or are retrofitted.
  • Aftermarket Devices: These devices do not connect to the vehicle’s computers; they draw data only from the environment (e.g., GPS, safety messages from other vehicles) to support applications. Aftermarket devices can emit the basic safety message to warn equipped vehicles of the vehicles presence as well as warn drivers of potential conflicts. This option is being examined as a means of increasing user adoption, and hence benefits, especially in the existing fleet of over 250 million vehicles.
  • Vehicle Communications Devices: These devices focus only on emitting the basic safety message.


In the Model Deployment approximately 3,000 vehicles will participate. Sixty-four vehicles will have embedded devices; approximately 300 vehicles will have aftermarket safety devices; and the remaining vehicles will have simple transmission-only vehicle awareness devices.There will be three trucks integrated with wireless crash warning devices that will be part of separate truck driver clinics. These driver clinics will obtain a cross-section of commercial vehicle drivers, recruited from local fleets and other means. The drivers will operate the vehicles in a safe, highly controlled, closed-course environment with a focus on collecting subjective driver acceptance data on integrated safety systems and driver vehicle interfaces.

Recruitment goals and methods

A car consortium led by the Crash Avoidance Metrics Partnership (CAMP) is responsible for all aspects of the driver clinics, ranging from project management, testing, recruitment of potential drivers, and overall management of the driver clinics.

CAMP Vehicle Safety Communications 3 is a cooperative research organization made up of eight of the leading car manufacturers including Ford, General Motors, Honda, Hyundai-Kia, Mercedes-Benz, Nissan, Toyota Motor North America Inc., and Volkswagen Group of America.

Who will be selected to participate in the driver clinics?CAMP will select a population of drivers split evenly by gender and by three age groups: younger (under 30 years of age), middle age (between 40 and 50 years of age), and older (over 60 years of age).

How will drivers be selected to participate in the driver clinics?In each of the six driver clinic markets, a market research recruiting firm that specializes in finding, screening, and inviting participants for all types of studies will recruit participants. The firms adhere to strict confidentiality standards.

To participate in the driver clinics, contact Helen Thomas, of Automotive Events, at

How many drivers are expected to participate?At least 100 volunteer drivers will be selected to participate in each of the six driver clinics.

What can participants expect?Each research participant will receive an explanation of the functions of the connected vehicle system and the test scenarios to be undertaken. Participants will then experience the different applications under a variety of scenarios. Following completion of each driver clinic, research participants will complete a survey designed to gather subjective driver acceptance data. At least one focus group meeting will follow each driver clinic.
