Disseminating Traveler Information on Travel Time Reliability
This online engineering PDH course discusses about the dissemination of Travel Time Reliability (TTR) information using a set of tested Lexicon phrases in order to help road users make optimal travel choices and reduce roadway congestion.
Travel time variability is a characteristic of the transportation system that means a traveler’s trip will vary from what is normally expected and will potentially take longer than planned. By helping travelers make travel choices that take into account travel time variability, agencies have the potential to reduce roadway congestion. This reduced congestion has the added benefit of reducing primary and secondary crashes, vehicle emissions, and fuel use, as well as yielding other benefits.
Travel Time Reliability (TTR) information includes static data about traffic speeds or trip times that capture historic variations from day to day and enable individuals to understand the level of variability in traffic. A key component to addressing the reliability issue related to urban mobility is conveying this TTR information to system users so that they can make informed decisions about their travel. The challenge for transportation professionals lies in selecting the best means of conveying that information so that it is usable and effective to the traveler and other stakeholders.
This 2 PDH online course is applicable to transportation engineers who are interested in helping travelers make better travel choices and in reducing roadway congestion.
