| 摘要： | Travel time reliability reflects the distribution of travel time of trips using a facility over an extended period of time. This distribution arises from the interaction of a number of factors that influence travel times: (1) Recurring variations in demand, by hour of day, day of week, and month of year; (2) Severe weather (e.g., heavy rain, snow, poor visibility) that reduces capacity; (3) Incidents (e.g., crashes, stalls, debris) that reduce capacity; (4) Work zones that reduce capacity and (for longer-duration work) may also influence demand; and (5) Special events (e.g., major sporting events, large festivals or concerts) that produce temporary, intense traffic demands which may be managed in part by changes to the facility's geometry or traffic control. |
