AGENDA ITEM #5REQUEST FOR FUNDING OF IMPROVED CORRIDOR TRAFFIC COUNTING -MARCH 3, 2005-
RECOMMENDED ACTION: • Letter to VDOT, DRPT, TPB, and NVTA supporting the initiation of a pilot counting program in Fall, 2005 using VDOT technical assistance funds at TPB. • If the pilot is successful, continue an ongoing, full program in FY 2007 using additional funding sources.
BACKGROUND: • TPB’s current regionwide traffic counts don’t allow statistically significant measures of mode shares in corridors. Thus the importance of transit investments where they are most effective can only be estimated.
VDOT’s annual performance measurement of HOV lanes in Virginia doesn’t include specific transit counts or parallel highways.
TPB staff prepared a scope of work for expanding either the HOV counts or the regionwide counts to provide two-day counts at two screenlines to enable valid mode share determinations.
The added cost is $250,000 per survey (surveys would be needed every three years).
VDOT’s federal technical assistance funds alone probably can’t absorb the entire cost, so other sources are needed, such as CMAQ.
A pilot project in Fall, 2005 could count for two-days on parallel facilities and one day on mainlines (I-66 and I-95/395/Rt.1) at one screenline on both corridors or at two screenlines in one corridor for $125,000. Alternately, only one screenline in one corridor could be counted for about $62,500.
