Question
Chapter 5, Problem 1P
To determine
The difference between short-term and long-term driver expectancy with an example.
Expert Solution & Answer
Explanation of Solution
Given:
Short-term and long-term driver expectancy.
Drivers depend on their expectations regarding the road layout and road-related examples when driving. Despite data processing and visual inquiry limitations, drivers cope well, even at high speeds, both because roads are generally planned because of driver impediments and because drivers depend on their experience.
Drivers develop both short-term and long-term driver expectancies. Example of short-term expectancies incorporates after going at a moderately fast taking wide distance, that the drivers may expect that the designed ahead road was accommodated to the similar speed.
Example of long-term expectancies incorporate when moving toward convergence, drivers should be in the left path to make a left turn at the crossroad.
Conclusion:
One approach to accommodate for human data processing limitations is to plan roadway conditionsas per driver expectations.

Post-tensioned AASHTO Type III girders are to be used to
support a deck with unsupported span equal to 90 feet. One level
of Grade 270, 10 x 0.6" Ø 7-wire strand are used to tension the
girders. The girder is simply supported at both ends. The anchors
are located 2" from the neutral axis at the supports while the
eccentricity is measured at 14" at the midspan.
Use maximum values for ranges (table values).
