1. Module Description
"Automated vehicles open up possibilities for saving lives, saving time, and saving fuel. Automated vehicles promise to move people and goods more efficiently than we are moving them today." "Today I am announcing that the President is proposing $3.9 billion over 10 years to fund pilot projects that help accelerate the development and adoption of safe vehicle automation." - U.S. Department of Transportation Secretary Anthony Foxx, January 14, 2016
This module is a continuation of Module 11 - Transit and the Connected Vehicle Environment/Emerging Technologies, Applications, and Future Platforms. Module 11 described the connected vehicle environment using Dedicated Short Range Communications (DSRC), relevant standards, and transit applications including those in the FTA Integrated Dynamic Transit Operations (IDTO) program.
The purpose of this module is to expand discussion on the connected vehicle environment for transit to accommodate "advancing automation" in the USDOT 2015-2019 ITS strategic plan and in the recent initiative announced by the USDOT.
Module 18 will provide transit agencies and other interested participants with an overview of developments in vehicle automation that complement vehicle connectivity for both bus and rail transit. This module will define relationships between connectivity and autonomy for transit vehicle operation. It will present examples of the state-of-the art transit vehicle automation applications including autonomous lane keeping and collision avoidance warning systems. This module also will describe how connectivity and automation are being deployed in rail transit, primarily in terms of train control systems for safety and capacity.
Distinguishing Automated Vehicles from Connected Vehicles
Automated or autonomous?
- Automated - perform a task using machinery or computers rather than humans
- Autonomous - having the power to control oneself, make decisions
Two types of connectivity
- Connect by using Dedicated Short Range Communications technology (DSRC) for Vehicle to Vehicle (V2V) and Vehicle to Infrastructure (V2I) communications
- Connect vehicles as the Internet of Things (IoT) using commercial Wi-Fi and cellular technology
"Connected Vehicles" is a term used by the US Department of Transportation to describe a roadway environment in which wireless communications permit vehicles to communicate with other vehicles, (V2V) and with stationary devices such as traffic signals, (V2I.) Numerous benefits are posited for connected vehicles. However, connectivity does not necessarily imply that vehicles will be automated. V2V and V2I could present information to a human driver that would warn of an impending collision, but the driver would be required to act to avoid the collision.
Automated vehicles do not necessarily require wireless communications to function. Automated driving systems can use various types of sensors to acquire data about the driving environment, which is processed internally. Signals are sent from the automated driving system to the electronic components controlling vehicle steering, acceleration, and braking, to manage the driving task. Although GPS, which is a wireless communications technology, is widely used for navigation, other navigation systems such as inertial guidance, gyros, and compasses can provide location and direction to the automated driving system. Likewise, although local area wireless Internet communication is frequently used to upload software and data to an on-board automated driving system, other ways to exchange data may be used.
NHTSA Levels of Automation
In the Federal Automated Vehicles Policy released in September 2016, NHTSA changed its original five levels of automation (0 to 4) to correspond with the six levels of automation developed by SAE International which are similar to those developed by the German Federal Highway Research Institute. The six levels of automation are the following:
- At SAE Level 0, the human driver does everything.
- At SAE Level 1, an automated system on the vehicle can sometimes assist the human driver conduct some parts of the driving task; examples are anti-skid braking (ABS) and electronic traction control (ETC).
- At SAE Level 2, an automated system on the vehicle can actually conduct some parts of the driving task, while the human continues to monitor the driving environment and performs the rest of the driving task; examples are adaptive cruise control and lane-keeping assist.
- At SAE Level 3, an automated system can both actually conduct some parts of the driving task and monitor the driving environment in some instances, but the human driver must be ready to take back control when the automated system requests; Tesla Autopilot is an example.
- At SAE Level 4, an automated system can conduct the driving task and monitor the driving environment, and the human need not take back control, but the automated system can operate only in certain environments and under certain conditions; Google and Uber retrofitted vehicles are examples
- At SAE Level 5, the automated system can perform all driving tasks, under all conditions that a human driver could perform them. Google's small two-passenger car with no steering wheel, brake and accelerator pedals is an example.

Distinguishing Full Automation from Less-Than-Full Automation
NHTSA Levels 3 and 4 require the driver to take over when the system determines it no longer can accomplish the driving task. NHTSA Level 5 is defined as performing all aspects of the driving tasks under all conditions. The only human function would be to input the destination or point to which the vehicle is to navigate. Full automation permits operation of an unoccupied vehicle.

Positive Train Control
What is Positive Train Control?
"Positive Train Control" (PTC) describes technologies designed to automatically stop a train before certain accidents caused by human error occur. Specifically, PTC as mandated by Congress must be designed to prevent:
- Train-to-train collisions
- Derailments caused by excessive speed
- Unauthorized incursions by trains onto sections of track where maintenance activities are taking place
- The movement of a train through a track switch left in the wrong position
The Rail Safety Improvement Act of 2008 (RSIA) requires passenger railroads and Class I freight railroads to install PTC by the end of 2015 on main lines used to transport passengers or toxic-by-inhalation (TIH) materials.
The PTC systems that will be installed to meet the statutory mandate are overlay systems, meaning they supplement, rather than replace existing train control systems.

SAE J3018 Guidelines for Safe On-Road Testing of SAE Level 3, 4, and 5 Prototype Automated Driving Systems (ADS) Scope: This document provides guidelines for the safe conduct of on-road tests of vehicles equipped with prototype conditional, high, and full (levels 3-5) automated driving systems (ADSs), as defined by SAE J3016. It does not include guidance for testing production ADSs intended for sale to the general public. The scope is further limited to testing of automated prototype vehicles on public roads. These guidelines do not address: • Testing of driver assist (Level 1) or partial (Level 2) automation systems, which rely on a human driver to monitor the environment. (See SAE J3016 for Definitions of Levels of Automated Systems.) • Closed-course testing. • Component-level testing. The precise regime of road testing for a particular prototype will depend on the intended level of automation and the targeted capabilities of the prototype (see SAE J3016 for more information). A prototype suitable for testing on public roadways is presumed to have already passed laboratory and/or closed-course testing, which are not addressed by this document.
SAE 3092 Dynamic Test Procedures for Verification & Validation of Automatic Driving Systems (ADS) This document provides dynamic test procedure information and guidelines for verification and validation (V&V) of automated driving systems (ADSs). The levels of automation addressed in this document include conditional (level 3), high (level 4), and full (level 5) as defined by SAE J3016; when activated, these ADSs do not rely on a human driver for monitoring and responding to the vehicle or traffic environment.
SAE J3131 Automated Driving Reference Architecture SAE J3131 defines an automated driving reference architecture that contains functional modules supporting future application interfaces for Levels 3 through 5 (J3016). The architecture will model scenario-driven functional and nonfunctional requirements, automated driving applications, functional decomposition of an automated driving system, and relevant functional domains (i.e., functional groupings). Domains include, but are not limited to, automated driving (i.e., automation replacing the human driver), by-wire and active safety, and those related to automated recovery from faults and system failures (e.g., system bringing the vehicle to a safe state). The architecture will address Tier 1 and Tier 2 functional groupings. The document will include one example instantiation being divides the functionality into two functionality groupings, and will detail the functional and information interface between the groups.
