This document is Volume IV of the final report on precursor systems analyses of the Automated Highway System (AHS). It analyzes the requirements, issues, and risks associated with lateral and longitudinal control of vehicles operating on the AHS. This report presents a possible evolutionary path for the automation of lateral and longitudinal control. This evolutionary path is characterized by five evolutionary representative system configurations (ERSCs). This analysis looks at the development of longitudinal, lateral and finally combined lateral and longitudinal systems in terms of the performance and reliability requirements and deployment scenarios. The performance requirement analysis covers driver comfort and acceptance issues during automatic control and transitions between automatic and manual control in addition to investigating the sensor, actuator and controller requirements for the control systems. Roadway traffic controllers may improve traffic flow through traffic networks in terms of travel time reduction and congestion avoidance. The reliability requirements analysis uses NHTSA's accident rates data to quantify the reliability requirements in various levels of vehicle automation. This report derives the reliability functional requirements for the automatic systems used in lateral and longitudinal control. The reliability functional requirements allow us to assess the required redundancy and structural complexity in implementing these automatic systems. This information can be used to estimate the cost and difficulty to build the automated highway systems.
