Problem $5.$ Consider the intersection information shown below $-$ physical layout, peak hour volumes, saturation flows, and signal phases. The speed limit on all approaches is $30mph.$ Lanes are $11$ feet wide on Easy Street and $13$ feet wide on High Road. There is no heavy vehicle traffic on Easy Street, so the design vehicle is $12$ feet long and has a deceleration rate of $20f\frac{t}{s^2}.$ Buses run along High Road, so the design vehicle is $25$ feet long and has a decleeration rate of $10f\frac{t}{s^2}.$

Are the yellow times on each phase sufficient to prevent dilemma zones? $($I have not taught you about dilemma zones for turning traffic, just consider traffic driving straight through.$)$

Compute the delay for each lane group, each approach, and the intersection as a whole.
