The examination of ground transportation conditions at the Los Angeles International Airport (LAX) suggests that while there is still some potential street and freeway capacity left, future problems may arise. Ground transportation limitations require that means must be found either to decentralize departing flights or bring arriving passengers to the airport by other means. The Department of Airports proposes a system of satellite airports and metroports, utilizing flying buses or VTOL/STOL aircraft to transport passengers around the metroport area. To be successful, the system should provide a flat rate fare for all passengers, regardless of their airport destination.

Various components of new technology exhaust emission control systems were disabled on five Automobile Club of Southern California fleet vehicles. Prior to and following disablement, a Federal Test Procedure and Highway Fuel Economy Test was performed on each vehicle. In addition, four short test methods were performed to determine their effectiveness in detecting the disablements. Results indicate the effects of the disablements on exhaust emissions, fuel economy, driveability and horsepower; and show the detection rate of the short test methods. Conclusions and recommendations are made regarding the effects of the disablements and the potential for preventing and/or minimizing those effects. The ability of different test methods to identify disabled emission control systems are discussed. Recommendations are made for further research with emphasis on testing of current and future emission control systems, and methods by which system failures can be identified.

A study was conducted to discover if the long-term effect of the lap belt reminder system on 1972 cars would be to increase belt-use frequency. Automobile Club of Southern California employees driving fleet vehicles equipped with specially designed hardware were used to perform the study. Driver lap belt usage was measured with the buzzer and light reminder system disconnected (to determine use rates under normal conditions) and then with it operating (to determine use rates in response to the reminder system). Conclusions are: 1. Approximately one third of the individuals who did not use lap-belts will become users for the majority of vehicle trips when the reminder system is operative. The reminder system will also increase usage of lap belts by individuals who used them only on occasion. 2. This study could not establish a significant relationship between lap belt use (with and without reminder system) and miles per vehicle trip, trips per day, and test subject demographics. 3.

Exhaust emission and fuel consumption data for 1974 and 1975 California automobiles were generated using the EPA Federal Test Procedure. Fuel consumption data were also generated from a highway cycle test and in-service vehicle fleet records. Emission test results indicate the degree of control achieved when compared to previous model year automobiles. Fuel consumption data comparisons were made among published data, data calculated using the indirect approved method, a direct method, and in-service fleet vehicle records. Conclusions discuss emission reductions achieved and the cost of future reductions. Further research to investigate fuel consumption measurement methods is suggested.
