Missing Movements 1: I-55 Northbound to I-64 Westbound: Part 1A

One minor update gained from recent travel in the area on Jefferson Avenue:

Regarding the stoplight at Jefferson Avenue and Chouteau: From the time the light turns red for Northbound Jefferson Avenue until the green left turn arrow for Northbound traffic comes up is about 52 seconds, so I would estimate at least a one minute delay incurred by missing this light. This adjustment would make change the adjusted time for this route from 12.11 minutes to 12.61 minutes. Still assuming the other stoplights are not coordinated, and still lacking data on most other signal timings, this would only drop the I-44/Jefferson route by one position - under the 12.25 minute Gravois/Tucker/Clark Avenue Entrance route.
