Model System Outputs

What outputs does the model system produce, and what Indicators should be developed from these outputs for evaluation purposes? Below is a preliminary set to begin the process. Please add and edit as needed.

Land Use Outputs (UrbanSim)

• Same as model inputs, but updated by simulation: households, persons, parcels, buildings, jobs, workplaces

Activity-based Travel Demand (AMOS)

• Activity patterns for each person and household in the data, including activity schedule (to a minute), modes, destinations
• Vehicle and person trips (individual, micro-level)

Dynamic Traffic Assignment (MALTA)

• Skims of shortest paths and associated times
• Vehicle routing and travel time experienced during simulation

Indicators Generated from Model Outputs

Land Use

• Densities of development at varying levels of aggregation (traffic zone, city, district, etc)
• Types of land uses and mixtures within different location types (e.g. Transit Oriented Development)
• Profiles of household types by area (poverty concentration, other forms of clustering by life cycle, social characteristics)
• Employment patterns (clustering by industry and location)
• Accessibility measures: fraction of persons or households by type within walking distance of transit; average travel time to work or other activity, measures of transportation options available to persons in different locations

Travel

• Level of service by facility and time of day
• Mode shares
• Transit trips by route and time of day
• Vehicle miles traveled
• Person jours of congestion delay
• Generalized costs of travel
• Emissions
