SPM Scenario Analysis

SPM analytical engines produce a range of critical metrics that allow for meaningful comparisons across different land use and transportation scenarios. Once changes are made to the base canvas via painting or translation of existing plan, scenario core processes combine the changes or growth input with the existing conditions to create future scenarios and estimate developable land and demographic characteristics. These scenarios then run through other model engines briefly described below to measure their performance for mobility, air quality, public health, fiscal impacts, resource consumptions, and others.

Land Consumption Engine

Land Consumption Engine

Land consumption refers to the measurement of land area needed to accommodate new growth. For a future scenario, SPM analyzes the greenfield land consumed to accommodate new residential and employment growth, as well as the growth that occurs via reuse or intensification on previously urbanized land (refill development).

Fiscal Impact Engine

Fiscal Impact Engine

Fiscal Impact Engine estimates the impacts of variations in residential development unit types and patterns on capital infrastructure costs, operations and maintenance (O&M) costs, and revenues.


Building Energy Engine

Building Energy Engine

Building Energy Engine calculates residential and commercial building energy use, and their related costs and greenhouse gas (GHG) emissions, for both new and existing buildings.


Water Engine

Water Engine calculates indoor and outdoor residential and commercial water use, and their related costs and greenhouse gas (GHG) emissions, for both new and existing buildings.


Transportation Engine

Transportation Engine

SPM incorporates a comprehensive "sketch" travel model that produces vehicle miles traveled (VMT), mode choice, and congestion estimates for land use and transportation scenarios, as well as transportation-related costs, greenhouse gas (GHG) emissions, and pollutant emissions.

Public Health Engine

Public Health Engine

SPM measures the impact of land use patterns and urban form on a range of health-related indicators. Public health metrics include physical activity-related weight and disease incidences, pedestrian safety measures, and respiratory impacts.​​​​​​​​​​​​​​​​​​​​​​​​​
