Abstract
.This study aims to Study on the accuracy and reliability of the travel time from the information Digital a real time from creating predicted by information derived from the journey. The time of day is 3.Rush hour morning (7.00-10.00.)) urgently. (time apart from the rush hour, morning and evening rush hour evening (16.00-19.00.)By the data used in the real time transportation travel time from Google map indices from the data Longdo traffic distances used in travel. The categories of data import and export cities.By the time on the bus. Then the data were analyzed by multiple regression. To establish the equation the travelling time. And the precision and reliability of each equation.2 equation by first order equations using index Longdo distances, and import and export in the prediction of travel time, กับสมการ second distance. And the import and export in the prediction of travel time. The equations of both the Root Men Square Error (RMSE) and Mean.Deviation (MAD), then the RMSE MAD and two equations were compared by the first equation RMSE MAD value and less than the second equation So we choose to use first order equations in the prediction of travel time. Then the equation to analyze the value and RMSE MAD.RMSE MAD and least. It can be concluded that we can use the index Longdo distance information and the import and export. In the prediction of travel time at the time outside the urgent precisely and most reliable
