| 摘要： | In the traffic engineering field, study and analysis often requires the use of multiple datasets. The nature of these data often makes them difficult to work with, especially in conjunction with one another. The overall goal of this study was to not only design a solution to this problem for the Buffalo-Niagara Region of western New York, but to demonstrate its usefulness through a specific application. To meet these objectives a prototype data warehouse was first created. The warehouse was and then tested on two applications. In the first application, the warehouse was used in the creation and validation of three incident detection strategies: a speed threshold detection system, a binary probit model which uses only speed data, and a binary probit model which uses a combination of speed and volume data. In the second application, the data was used to test the accuracy of weather impact models which had been previously developed. |
