A railroad track is crossed by a minor street that intersects a major street that runs parallel to the railroad track. There is a concern about queuing of minor street traffic, controlled by a STOP sign at the intersection with the major street, backward onto the track. Determine whether this intersection meets MUTCD Warrant 9, given the following data below:
? Major street peak hour volume (two-way): 320 veh/h ? Minor street peak hour volume (on the one-lane approach that crosses the tracks): 120 veh/h; 6% of which are tractor-trailer trucks; bus traffic is negligible ? Rail traffic is an average of 8 trains per day distributed in a scattered manner throughout the day ? The distance on the minor street between the nearest rail of the track and the STOP line at the intersection with the major street is 96 ft. What will be an ideal response?
How much lead, in pounds and/or ounces, is required to complete this assembly?
Fill in the blank(s) with the appropriate word(s).
