Learning Objective 1

Describe the connected vehicle environment

Slide 7:

Illustrate the CV Environment

This slide has a graphic showing the high-level physical view as taken from the Architecture Reference for Cooperative and Intelligent Transportation (ARC-IT) website. This base graphic shows the major types of subsystems within the reference architecture: Center, Support, Field, Vehicle, and Traveler. It also shows the links that exist between them (which includes every possible combination, including self-referential links, other than Traveler-to-Traveler). The Vehicle-to-Vehicle link is labeled "V2V" and the Vehicle-to-Traveler link is labeled "V2P"; these two links are highlighted in green (after the first click) and indicated as being the topic of this module. The links between the Vehicle or Traveler and the other major subsystems are labeled "V2I", highlighted in blue (after the second click), and indicated to be the subject of Module CV261. After the third click, a red box encircles the Traveler to emphasize that this module covers travelers in addition to vehicles.

Cooperative ITS (C-ITS) vs. Traditional ITS

This slide includes a USDOT graphic of an intersection with several connected vehicles. It is intended to demonstrate that each connected vehicle is its own system, potentially operated and maintained by a different entity, yet all of these distinct systems need to interoperate in a system of systems.

Slide 11:

V2V vs V2I

V2V course (this course):

V2I course:

V2X is Vehicle-to-Anything

This slide includes a picture of an in-vehicle display that is warning the driver of an approaching emergency vehicle; this is one example of a vehicle-to-vehicle application.

Slide 12:

Illustrate the CV Environment

Vulnerable Road Users

This slide includes a graphic of two pedestrians crossing at a crosswalk with one of them holding a connected device (such as a smart phone) that is conveying information to a roadside device, which is forwarding the information to the vehicle and producing a pedestrian warning. This same type of service could be implemented directly if the smart device and vehicle operate on the same communications network.

V2V Basic Safety Service Use Cases

This slide contains a graphic that shows a top down view of a three-lane roadway, with two lanes moving left to right, and one lane moving right to left. This is an animated slide. First, the text "Do Not Pass Warning" appears above the roadway along with the depiction of two connected vehicles traveling from right left (in the only lane in that direction), and one connected vehicle traveling in the opposite direction in the inside lane. An arrow indicates the direction of travel for each lane. Second, the text "Lane Change Warning + Blind Spot Warning" appears below the roadway on the left. and another connected vehicle is depicted traveling from left to right in the outside lane, slightly ahead of the connected vehicle in the inside lane, so that the inside vehicle is in the outside vehicle's blind spot. Third, the text "Forward Collision Warning" appears below the roadway on the right along with two connected vehicles traveling left to right in the right lane, one immediately behind the other. The lead vehicle has its brake lights on. Fourth, the text "Emergency Electronic Brake Light" appears below the roadway in the middle along with a third connected vehicle in the right lane just behind the two vehicles associated with the Forward Collision Warning application.

V2V Basic Safety Service Use Cases

The slide contains a graphic that shows a top down view of an intersection. Each approach to the intersection has two lanes in each direction. This is an animated slide. First, the text "Intersection Movement Assist" appears at the left bottom corner of the intersection along with a connected vehicle traversing the intersection from left to right in the right lane. A second connected vehicle is travelling bottom to top, crossing the crosswalk and just about to enter the intersection in direct conflict with the first connected vehicle. Next, the text "Left Turn Assist" appears in the upper right corner of the intersection; along with a connected vehicle making a left turn from the left lane, moving left to right; another connected vehicle is traversing the intersection from the opposite direction.

V2V Safety Services

This slide has two graphics. The first indicates a line of three stopped cars with a fourth approaching. In front of the lead car is a downed tree. The lead car is transmitting messages back to the cars behind it. The second graphic indicates a work zone with workers and work vehicles with the vehicles transmitting information to each other.

V2V Mobility Services

V2V Environmental Services

This slide shows a freeway where the inside lane has been separated from the main lanes with the use of pylons. The vehicles traveling in the reserved, inside lane are all shown as being connected and in communication with each other on a green pathway that indicates that they are platooned together as a group.

Identify V2V Services

Vehicle-to-Pedestrian (V2P) Safety

In 2017, a third of fatalities were vulnerable road users:

Author's relevant description: The first chart shows the proportion of fatalities inside and outside of a vehicle from 1975 through 2017. The proportion of fatalities outside of the vehicle varies from just under 30% from 1975 through the mid-1980s and then falling off to 20% from about 1996 through 2003. The proportion of fatalities outside of the vehicle then increases to just over 30% in 2012 where it seems to stabilize through 2017.

Increase since 2009 has been in those aged 20-69 (from 1.6 to 2.2 per 100,000)

Author's relevant description: The second figure chart has a title "2018 is projected to have the largest number of pedestrian fatalities in the U.S. since 1990." The chart shows pedestrian fatality numbers from 1990 through 2018. The 1990 data point is labeled as 6,482 and is followed by a steep decline such that in 1992 the number is roughly 5,500, where it stabilizes for about five years before falling again until it reaches a low of just more than 4,000 in 2009. The drop then quickly reverses and increases to a projected 6,227 in 2018.

V2P Mobility

Author's relevant description: This slide presents a graphic from USDOT's Accessible Transportation Technologies Research Initiative (ATTRI) program. It depicts a 5-step process around a center icon of a medical technician looking at a smart phone with the label "Caregiver, Family, and Safety Alerts. Connected Citizens. Associated Services." The five icons of the five step process include: a user booking a trip on a smart phone, a visually challenged individual at a transit stop being assisted by a robot, the same individual on a bus being alerted by his smart phone to pull the stop cord, the same traveler being guided when to cross the street by his smart phone, and arriving at his destination.

Slide 19:

Societal Benefits of Connected Vehicles

This slide presents 9 icons, arranged in 3 rows by 3 columns, to explain the benefits of connected vehicles. The top row focuses on safety benefits and depicts a street view icon showing a person in a 360-degree circle symbolizing 360-degree visibility. The second is a warning sign with an exclamation point symbolizing that CVs identify hazards. The third is a vehicle with a collision symbol symbolizing that CVs reduce crashes. The second row focuses on mobility benefits and depicts a chart with a downward trend symbolizing that reduced crashes results in reduced congestion, the second icon on this row depicts a person in a wheelchair symbolizing how CVs increase mobility for those with disabilities, and the third icon shows a traffic signal head, which is used to symbolize smoother traffic flow. The third and final row indicates a truck, which is used to symbolize that reduced congestion results in reduced emissions; a thumbs-up sign, indicating that smoother traffic also reduces emissions, and finally two gears working symbolizing that improved efficiency of automated systems can also reduce emissions.
