VE Definitions UNDER CONSTRUCTION
*** NOTE: This page will be a cliff-notes version of Mar2019 VE Training notes which better integrates with other existing wiki resources, and can be used in training.***
Definitions used by VisionEval, organized by the following VERPSM Concepts
- Household Synthesis
- Vehicles & Fuels
- Congestion, freight, and emissions
- Budgets & non-auto modes
- Local policy actions
- Setup & Validation
VERSPM Packages: (VESimHouseholds, VELandUse) + VEHouseholdVehicles-AssignDrivers?

Geography: Something like slide 11 of VE Training Slides.
-
Age groups (for persons and workers): 0-14, 15-19, 20-29, 30-54, 55-64, 65+
-
Lifecycle (aggregated NHTS definition) – used in multi-modal travel module
- 01: one adult, no children
- 02: 2+ adults, no children
- 03: one adult, children (corresponds to NHTS 03, 05, and 07)
- 04: 2+ adults, children (corresponds to NHTS 04, 06, and 08)
- 09: one adult, retired, no children
- 10: 2+ adults, retired, no children
-
Annual income???

Types of househoSomething like slide 39 of VE Training Slides. lds:
- Regular households - related and unrelated persons living in the same dwelling unit
- Group quarters households - persons living in non-institutional group quarters such as college dorm (household size =1)
-
Types of dwelling Units:
- Single-family (SF)
- Multifamily (MF)
- Group Quarters (GQ)
-
Home and Work Location Types:
- Urban - located within an urbanized area <MORE HERE...vs. "urbanized">
- Town - located in a smaller urban area that does not have enough population to qualify as an urbanized area
- Rural - located in an area characterized by low density dispersed development
-
Bzone-level Built Form “D” variables, based on EPA Smart Location Database definitions
-
DENSITY
- Population density (EPA SLD D1B)
- Employment density (D1C)
- Activity density (employment + households) (D1D)
-
DIVERSITY
- ratio of jobs to households (D2A_JPHH)
- ratio of workers living in the zone to jobs located in the zone (D2A_WRKEMP).
- entropy measure calculated from the number of jobs by sector and number of households (D2A_EPHHM)
- Destination ACCESSIBILITY measure (D5), harmonic mean of jobs within 2 miles and population within 5 miles of the Bzone centroid
- Pedestrian-oriented network **DESIGN **measures (D3bpo4), an input
- Bzone-level Urban MIXED USE measure. Based on the 2001 National Household Travel Survey measure of the block group level urban/rural indicator. This measure developed by Claritas uses the density of the tract and surrounding tracts to identify the urban/rural context of the tract and identified 4 categories: urban, suburban, second city, town and rural. The urban category roughly corresponds to the inner portions of urbanized areas that are generally characterized by more urban and mixed-use development.
