| Summary: | 碩士 === 國立中央大學 === 土木工程研究所 === 91 === Highway is entrances and exits’ controlled section of highway; therefore, drivers who want to enter highway should pass through entrance ramp. All kinds of interference which happen when rampconverges vehicles would produce effect of travel time to drivers. Moreover, traffic information is an important reference for users’ behavior decision, for example, it can help drivers to choose the suitable path and time in order to avoid traffic jam. And the use of immediate traffic information to predict travel time would be essential in the future.
The research focus on the definitions of the changing driveway behavior of the entrance ramp converges road of highway and the behavior motivation and conditions of the speed-up driveway merge in the mainline, and goes a step further to write simulated model then discuss the experimental combinations of related parameter about different flow types, the time of data-gaining, the distance of the speed machine setting and so on. At the same time, the parameter data which collected by the speed machine are using by the nerve-like to forecast the travel time to expect to provide the precise prediction of the travel time and become the users’ path-choosing and leave time reference.
Through proofreading and testing repeatedly, this research’s travel time forecasting pattern belongs to “high-precise prediction.” In the aspect of the entrance ramp converges road of highway’s travel time prediction, it can also provide the embryo of the travel time forecasting to the related traffic departments
