This report describes the Stage II work –Analysis, Modeling, and Simulation(AMS) – to date of the US Department of Transportation’s (DOT) federally-sponsored Integrated Corridor Management (ICM) Program for the I-15 Corridor in San Diego County, California, between State Route 163in the city of San Diego and State Route 78 in the city of Escondido. Stage II of the federal ICM Program involves performing the analysis, modeling, and simulation work for the I-15 corridor in San Diego County. Major tasks in Stage II consist of data collection, tools and software support, models validation and...

This report presents and describes 400 aviation accidents which occurred within five miles of an airport. Section 2 contains a description of the development of the database and a discussion of the criteria used in selecting accidents for the database. Section 3 provides a description of the database itself as well as a set of statistics that provide a comprehensive overview of the accidents. A set of aircraft accident contours developed from the accident data points is presented in section 4. The purpose of these contours is to provide a picture of the distribution of accidents over space...

Being a public resource, the roadway space was distributed between different road users based on the Passenger-Car-Unit (PCU) concept. However, this concept tends to under estimate the capacity of public transportation and non-motorized travel. To improve the traditional car-oriented design to become more human-oriented, this study proposed a Passing-passenger-unit (PPU) and the method to observe the PPU in roadway level and area level. The PPU data were collected for urban arterials and residential areas in China to test the method and to compare the right-of-way distribution at different...

This report documents the findings of the study “Vehicle/Driver Monitoring for Enhanced Safety of Transit Buses” conducted as part of the PATH project TO5400. The goal of study TO5400 is todesign and implementation of a reliable vehicle/driver monitoring system with aim to enhance driving safety of transit buses.The main objectives of the project are: (1) to identify a simply model that best describes the driving patterns of human drivers, and (2) to develop an algorithm which can generate warning messages when there is a provision of danger.In this study, it is assumed that the driver...
