the employment population for the redeveloped NASB as a site-specific analysis
the 2009 employment population for the Towns of Brunswick and Topsham as
both site-specific and areawide analyses
the 2009 employment population for the Brunswick LMA as an areawide
analysis
The TDM measures outlined in Chapter 4 were included under all analysis scenarios;
however, two model inputs were adjusted under the various employment scenarios
to understand the range of TDM reduction that could be achieved. The first model
input tested is the “Employer-Support Programs” level, which the first COMMUTER
model defined as follows:
Level 0: No program
Level 1: Provision of information activities plus a quarter-time transportation
coordinator
Level 2: Level 1 plus in-house matching services for carpool and vanpool, workhours
flexibility, or bicycle parking and shower activities
Level 3: Level 2 plus a half-time transportation coordinator plus preferential
parking for carpool and vanpool, on-site transit pass sales, or secure bicycle
parking and local infrastructure improvements for bicycle travel
Level 4: Level 3 plus a full-time transportation coordinator plus additional
financial and technical support for carpool and vanpool, guaranteed ride home,
or workplace promotional activities
The three population groups considered in the TDM evaluation considered
Employer-Support Program Levels 2 and 4. GOMAINE serves as the transportation
coordinator for the Brunswick/Topsham area; therefore, regardless of whether
individual employers have their own transportation coordinator, the application of
the Level 4 Employer-Support Program is appropriate for the evaluation.
The second COMMUTER model input adjusted for analysis purposes is parking
costs that contemplate higher parking rates charged for single-occupancy vehicles
than for carpool or vanpool vehicles. The two scenarios evaluated to test the
sensitivity of higher parking costs for single-occupancy vehicles included increases of
$1 and $2 per day.
Section 5.2 discusses results of the TDM evaluation for each strategy and option
evaluated.
