b'How Strategic Models Can Help Practitioners Plan for ChangeIntegrating Strategic Modelshelp practitioners prioritize strategies and identify Into the Planning Process those that are most effective at meeting planning goals. These models are a fitting tool for early work Strategic models can quickly and efficiently evaluatein the long-range transportation planning process many future scenarios. This allows practitioners tosince they are designed to evaluate several possible explore futures based on changed circumstances andfuture conditions, identify high-return policies, and behaviorsincluding behaviors that might happeninvestigate the effects of various investment options. but have not yet been observed. Such hypotheticalThe permutations of all these options are numerous, behavior shifts could include changes in vehiclewhich can make detailed network modeling expensive ownership due to the accessibility and affordability ofand time consuming.ride-hailing services. Changes could also include a rise in the percentage of employees who work from homeInputs vary across the VisionEval modeling platform and no longer commute on all or most days. (Table 4). VERPAT has about half the required input files as VERSPM. While they all require development of Strategic models are best used after policy goalssome region-specific inputs, other inputs are optional have been identified by the planning agency involved,and can be run as defaults. The inputs can be grouped though they can also be used to inform decisionby changes in demographics and land use, policy and makers in the policy development process. They canpricing, and changes in supply.TABLE 3.SUMMARY OF STRATEGIC MODEL CHARACTERISTICSVERPAT VERSPM VESTATEGeography Level Regional Regional StatewideSimulated zones by Zones (TAZs) & aggregate zonesarea type & aggregate Zonal Structure Activity allocated to place types (typically cities or counties) & Mzones (typically cities areas (metropolitan areas) or counties) & M areas (metropolitan areas)VERPAT VERSPM/VESTATEAutomated & Fewer ITS improvements to reduceAutomated ride-hailing; number of ITS investments that can Connected Modes nonrecurrent congestion smooth traffic flow and reduce nonrecurrent congestionUser-specified powertrains for all vehicles except household Electric Modes PEV types and characteristics arevehicles; household PEVs are simulated based on cost, applied globally per model year availability, daily VMT range, and charging infrastructure availabilityTDM programs (carpooling, vanpooling, carshare), defineRide-hailing, carsharing, personal lightweight vehicles, define Shared Modes proportion of SOV trips suitable toproportion of SOV trips suitable to active modes; defined per active modes (micromobility, bikes);A zoneused globally in model areaOutput Granularity Results by place type Results by zones and metropolitan areasVERPAT/VERSPM/VESTATEPolicies Pricing, modal availability, land use, and demand management, among othersNotes: ITSIntelligent Transportation SystemPEVPlug-in Electric VehicleSOVSingle-Occupancy VehicleTAZTraffic Analysis ZoneTDMTravel Demand ManagementSource: RSG, 2020 2020 RSG 7'
