| 摘要： | Transportation agencies strive to provide reliable travel times for travelers and shippers, who want to avoid variability and delay in how long it takes to make a trip. Travel time reliability monitoring systems (TTRMS) can help transportation agencies--especially those with transportation management centers--monitor the performance of their system, understand the impacts of the various factors that influence travel time variability, provide credible information to the system users about what travel time reliability to expect, and decide what actions to take to help improve reliability. SHRP 2 Reliability project L02 developed guidance for operating agencies about how they can put better measurement methods into practice and understand the relationship that travel time reliability has to the seven major sources of non-recurrent congestion: traffic incidents, work zones, weather, special events, traffic control devices, fluctuations in demand, and inadequate base capacity. |
