Question $1$

There are currently two widely used methods for assessing the comfort of streets for bicy$-$

cling: Bicycle Level of Service $($BLOS$)$ and Level of Traffic Stress $($LTS$).$ LTS uses a scale of

$1$ to $4$ to rate the bicyclist's level of stress experienced while riding with $4$ being the most

stressful. BLOS uses a scale of A to $F$ with $F$ being the most stressful.

PART I $[20$ points$]$ Use the information provided below to calculate BLOS and LTS for this

segment and compare the two analysis techniques for a single street segment. Evaluate

the different inputs and resulting ratings. Consider what components lead to the ratings

based on your knowledge of the BLOS equation and the fact that LTS is a "weakest link"

assessment. Consider data about the street and what you know of bicyclists' comfort and

explain which assessment you believe is more accurate.
