Based on problem $1,$ assuming a vehicle occupancy of $1\mathrm{.}5$ persons$/$vehicle$,$

estimate three modal split assignment scenarios for AM and PM peak hours.

Scenario $1$: $100\%$ auto. Scenario $2$: $40\%$ auto, $30\%$ carpoolingwith average

occupancy $2\mathrm{.}4$ persons$/$vehicle and $30\%$ bus transit $($one bus every $10$min. enters

site from each direction$).$ Scenario $3$: $70\%$ auto, $20\%$ car carpoolingwith average

occupancy $2\mathrm{.}4$ persons$/$vehicle and $10\%$ rail transit. Sketch the AM volumes at

the access point for the three scenarios.
