Freight and Distribution

Key data components include annual productions by economic sector, employment by industry sectors, and in?migration and payroll by the economic sector. Besides economic production and industry employment data, this data also includes these sectors.
Production Allocations and Interactions: The production allocations and interactions module determines the distribution of production activity among zones and the consumption of space by these production activities in each zone. The module also reflects the flows of goods and services and labor from production locations to consumption locations, as well as the exchange prices for goods and services, labor, and space each year.
Household Allocations: Household allocations to zones reflect the same distributions as the allocations from the previous year. The labor flows originating from these households are allocated to the production locations based on the production allocations to zones determined from the production allocations and interactions data. Similarly, distribution of freight companies demand associated with household consumption activity is modeled by allocating the flows of commodities consumed by the households to zones based on zonal production allocations.
Land Development: The land development data estimates the year-to-year changes in available space in each zone in the region. The primary task of the land development data is to adjust the quantity of space over time in the region in response to changes in price. Other data in the model determine a price for each category of space in each zone using a highly dis-aggregate process, based on the fixed supply of space available in each zone for that particular year. The data uses the zoning patterns and does not forecast how the political process can change zoning patterns. This data does not include freight transportation.
