SHORT-TERM FORECASTS OF FREEWAY TRAFFIC VOLUMES AND LANE OCCUPANCIES, PHASE 2. VOLUME 5. (FREEWAY RAMP REAL TIME FORECASTING)

The research is part of a larger project that attempted to forecast freeway and ramp volumes, and lane occupancies for real time use in ramp metering applications, as well as forecast data collection efforts. Volume V looks at previous efforts at developing traffic volume forecasting methods, both in real time and off-line situations. Several models that have been developed are discussed to provide a foundation for this and future studies. A short, noncomprehensive review of these methods is given in Appendix A which discusses state-of-the-art efforts in this subject area. The majority of the research effort has been focused on checking the validity of work done by Zhu at the University of Washington in 1990 and furthering promising aspects of that work. A discussion of the reasoning can be found in Chapter 2, Research Design. Chapter 3 discusses the results of this research. The final chapter contains conclusions and recommendations.
