4 cards from this section. Quick, good the night before a test.
What are the four main traffic characteristics essential for data collection?
Think about what measurements would help understand traffic behavior.
What is an inductive loop detector used for?
Consider the technology that detects vehicle presence.
Which of the following is NOT a key traffic characteristic?
Focus on what metrics assess road usage.
True or False: The enoscope can measure speed over a distance.
Consider the function of enoscope.
During a moving observer test, an observer counts 50 vehicles overtaking the test vehicle going with the traffic, and 15 vehicles against the traffic over a 1 km stretch. Calculate the flow if the time taken for the observation is 20 minutes.
Make sure to convert minutes to hours when calculating flow.
If an inductive loop detector records 1000 vehicles in an hour, and two errors occur due to heavy vehicles in adjacent lanes, what is the adjusted flow and how would you present this error in a report?
Think about how this adjustment affects overall traffic assessment.
