Travel Time on Message Signs
| 项目名称： | Travel Time on Message Signs |
| 摘要： | One of the primary traveler information applications of interest throughout the Corridor is posting travel time on signs. With the successful launch of the I95 Vehicle Probe Project (I95VPP), increased attention has been given to this application, with several inquiries for guidelines to appropriately use the I95VPP data to post quality traveler information on changeable message signs. This application presents technical challenges of understanding the quality, data lag issues, and inherent predictability of travel time in order to create quality traveler information. As opposed to 511 and web services, the real-time requirements for quality information (and resulting negative feedback if such information is not accurate) put extra scrutiny on such applications. The objective of this project is to create a guide for the use of the I95 Vehicle Probe data as a source of posting travel times on signs, and recommended messaging to maintain consistency throughout the corridor. The guide will review existing practice within the Corridor for posting travel time information on Changeable Message Signs (CMS). Technical aspects such as best practices for smoothing, filtering, and aggregating sensor data will be addressed as well as policy aspects such as segment lengths, message content, and frequency of update. Case studies and lessons learned will be drawn from available applications within the Corridor regardless of data source. |
