Monte Carlo simulation: It is known that $15\%$ of the vehicles approaching an intersection will tu left, $60\%$ will go straight through and the rest will turn right. Construct the correspondi cumulative distribution and translate the following $20$ uniformly distributed random numbe generated $($each one of you would generate these on a spreadsheet. Also generate the tin headways of these vehicles if the mean and minimum headways are $3\mathrm{.}5s$ and $1\mathrm{.}0s$ respectively.
