Question

Two lanes of a freeway have been reduced to one lane for a short distance through a construction zone. A sign has been placed a few hundred feet ahead of the merge point stating "huse both lanes to merge point," and another one has been placed close to the poin: of lane restriction saying "merge bere."Literahure produced by the local department of transportation states that this practice reduces delay and increases this traffic management practice could expect to find that 29 the capacity through the construction zone. An engineer called on to analyze O (A) the oe-lane capacity and average sotal delay throogh the merge quece and constructioa zone is unaffected by the precise location of the 24 merge point, as long as the merge is within a few bundred feet ahead of the restricted zone 25 O (B the one-lane capacity is increased and the aversge total delay through the merge queue and construction zone is the last possible location ) 27 28 29 30 31 (C) the one-lane capacity remains the same but the average per vehicle delay or the tocal flow through the coast action zone is reduced b both lanes spproach the restriction as close as possible to the merge point O is increased but the average per- vehicle delay for the total flow through the construction zone is unaffected by havirg the ore-lane both lanes approch the restriction ax clon as posuble do thte menge point

Explanation / Answer

Ans C.

Because, engineer came to study that average number of vehicles per day and to study the delay studies at construction zone.
