Question - what is happening in the top-most loop (B1)?
(starting from B2) An increase in traffic volume increases the travel time
increased travel time increases pressure to reduce congestion
increased pressure to reduce congestion increases road construction
increasedroad construction increases highway capacity after delay
increased highway capacity decreases travel time
An increase in travel time creates pressure in this feedback loop for the expansion of roads by increasing highway capacity but there is a delay caused by road construction. As there is only one negative link on this loop, it is a balancing loop suggesting that after delay there will be a decreased pressure to reduce congestion hence decreasing road construction.
