Pedestrian travelshed assumed to be 0.5 mi/10 minutes. At-Grade alternatives assume existing pedestrian bridges would remain or be converted to mid-block crossings. At-grade pedestrian crossings would increase travel times to cross the corridor.

Bicycle travelshed assumed to be 3 mi/20 minutes. At-Grade alternatives assume existing pedestrian bridges would remain or be converted to mid-block crossings. At-grade bicycle crossings would increase travel times to cross the corridor.

Expected crashes per day are based on VMT per day and statewide average crash rates by facility type. Crash rates are per million VMT. F/A (fatal and serious injury) crash rates are per 100 million VMT. Routes within 1-mile do not include mainline crashes. Regionwide results were calculated but are not shown since no variation between the alternatives was observed.

Results represent corridor travel time for all vehicles (including freight) based on regional model output. Travel time is measured between the logical termini (I-35W/TH 55 to Marion St).
43
16
Calculated using weighted average peak hour volume to capacity ratio using regional model outputs. Travel Time Index (TTI) measures the reliability/variability of travel times. It is the ratio of corridor travel time in the peak period to travel time at free-flow speeds or uncongested conditions.
44
17
The final access configuration has not been determined at this time. This measure is intended to capture the addition or removal of access points for each mainline alternative based on assumed changes in the regional model. There are 10 existing access points within the existing 7.5-mile corridor.

48
21
Assumptions: (1) Low floor boarding on all buses and platforms, (2) off-board ticketing, and (3) multiple door boarding. Signal delay is not accounted for in this analysis. TTI measures the reliability/variability of travel times. It is the ratio of corridor travel time in the peak period to travel time at free-flow speeds or uncongested conditions.
