Show answer and explanation

Correct answer: (A) Moving observer; (B) Registration-number method; (C) Elevated observer

Explanation

Moving-observer surveys, matching vehicle registrations over a route, and observation from an elevated vantage can provide travel-time/speed information, A, B, C. Running speed excludes stopped delay; journey speed includes it. Hardy Cross is an iterative network-balancing method, not a direct traffic-speed survey.
