Integrated Modeling Approach The REMI model integrates key aspects of several economic modeling tools: Model I/O CGE Aspect Inter-industry processing sector Equilibrium tendencies in factor and material input markets Econometric Estimates derived from panel data Economic Geography Labor and product agglomeration
New Economic Geography n n n Based on monopolistic competition Increasing economies of scale for firms (decreasing marginal costs). Access to product varieties from different regions. Different delivered prices in the same industry due to transportation or other distance deterrence costs. Cross hauling, cluster agglomeration, and labor productivity are explained by microeconomic gains from having choice and variety.

Travel Demand Models Tran. Sight can be tailored to use outputs from a variety of commerciallyavailable or custom travel demand models. These include: • Tran. Plan • TP+/Cube • Trans. CAD • HERS-ST • Customized models The selected model should be run under both a baseline scenario and an alternative scenario that factors in the proposed transportation improvement
Travel Demand Models Variables from the travel demand models that are integrated with Tran. Sight to calculate the effects of a transportation project include: • • Vehicle miles traveled (VMTs) Vehicle hours traveled (VHTs) These inputs are needed for the following: • • • Each model region Each forecast year Road types (e. g. freeway, arterial) if available Time-of-day (e. g. , AM/PM Peak) if available Both the baseline and alternative scenarios

Construction and Maintenance Costs Overview: n Projected annual costs incurred by government for construction, maintenance and repair are entered by user n Project financing can be split between federal, state, and local government n Work is usually contracted out to private construction firms, which creates jobs and demand for intermediate inputs n Operation and maintenance costs more significant for public transit than roads
Construction and Maintenance Costs The EDFS-53 connection: • • Increased annual sales by the construction industry, to reflect expenses on construction and upkeep Government expenditures, apportioned to federal, state and local levels according to financing percentages
Enter construction cost data
Emissions Costs/Benefits Overview of theory: • Two countervailing effects of road upgrades • Increased miles traveled (emissions increase) • Increased average speeds (emissions decrease) Øbalance depends on speed changes of pre-existing traffic relative to percentage of new traffic • Dose-response functions connect emissions rates to incidence of various health maladies • Costs of health problems include lost work days and leisure activities, lower productivity, medical expenses • Public transit reduces emissions via substitution away from cars
Emissions Costs/Benefits Overview of data: • Emissions rates (grams/mile) vary by speed for each of five pollutants: • Carbon Monoxide (CO) • Volatile Organic Compounds (VOCs) • Nitrogen Oxides (NOx) • Sulfur Oxides (SOx) • Small Particulate Matter (PM-10) **EPA’s MOBILE 6 and PART 5 models are used to estimate these emissions rates.
Emissions Costs/Benefits Overview of calculation: Health costs (per gram of emissions) for each pollutant derived from nationwide or local impact studies, and may vary by year • Change in emissions costs computed as follows: • …where: ECj = Change in emissions cost for pollutant j ($) ERj = Emissions rate for pollutant j (gram/mile) CPGj = Emissions cost per gram for pollutant j ($/gram) VMTalt = Vehicle miles traveled under the alternative scenario VMTbase = Vehicle miles traveled under the baseline scenario
Emissions Costs/Benefits The EDFS-53 connection: Non-pecuniary amenities accruing to laborers and their dependents, which stimulates migration into or out of the region where the transportation project is completed, depending upon whether the benefits are net positive or negative
Safety Costs/Benefits Overview: n Benefits/costs of a transportation project include the following aspects u The values of injuries and lives lost* t This value may increase due to a gain in miles traveled t This value may decrease due to safety improvements u Property damage** u Delay due to automobile accidents** n May vary by year to reflect rising medical and insurance costs *Value taken from U. S. DOT estimation of the value of life (currently $3 mil/life) **Value taken from National Highway Traffic Safety Administration, The Economic Cost of Motor Vehicle Crashes 1994; Lawrence J. Blincoe, 1996
Safety Costs/Benefits Overview of calculation: • • Accident rates (per mile) should be derived from local data by road type, and can vary by year and time period (e. g. , A. M. Peak) if data availability permits Changes in safety costs computed as follows: …where: SCj = Change in safety cost for road/accident type j ($) ARj = Accident rate for road/accident type j (accident/mile) CPAj = Safety cost per accident for road/accident type j ($/accident) VMTalt = Vehicle miles traveled under the alternative scenario VMTbase = Vehicle miles traveled under the baseline scenario
Safety Costs/Benefits The EDFS-53 Connection: Non-pecuniary amenities to households, which stimulates migration into or out of the region where the transportation project is completed, depending upon whether the benefits are net positive or negative
Fuel Tax Changes Overview u § Change in fuel tax revenues proportional to change in gallons consumed, which can move two ways following a road upgrade: 1) Incremental travel demand: gallons increase 2) Higher average speeds of existing traffic: gallons decrease New or expanded public transit will induce substitution away from cars; magnitude of switch will determine tax revenue change
Fuel Tax Changes Overview of calculation u u Fuel efficiency varies by average speed, which may increase due to transportation improvement Changes in fuel tax revenue computed as follows: …where: FR = Change in fuel tax revenues for region i ($) FTi = Fuel tax rate for region i ($/gallon) Avg(MPG) = Average fuel efficiency (miles/gallon) VMTalt = Vehicle miles traveled under the alternative scenario VMTbase = Vehicle miles traveled under the baseline scenario i
Fuel Tax Changes The EDFS-53 Connection: The policy variable effect can be tailored to the client’s specifications: say, a change in funds available for government spending, or an adjustment to the model’s fiscal balancing mechanism
Commuter Cost Savings n Includes the following aspects u The amount of commuting cost saving for the entire county or counties over the average work day. • The value of commuting time is rated at half the wage rate. • This is adjusted for VHT changes (from the travel demand model), and based on average commuting time – Source: Census for county commuting patterns
Commuting Costs The EDFS-53 Connection: • • Commuting costs affect the effective distance in the occupational labor access productivity equation (by adjusting labor cost relative to the average wage rate), which feeds into industry labor access productivity and from there into composite wage rates This ultimately affects both the composite cost of production by industry and the relative wage rate in the economic migration equation.
Transportation Cost Savings n Includes the following aspects u The cost savings in transporting goods and services due to increase in transportation efficiency t These are calculated from changes in VMT and VHT between the alternative simulation and baseline control t Source: Travel demand model
Transportation Costs The EDFS-53 Connection: • • Transportation costs affect the effective distance in the delivered price equation for each sector (relative to time and to wage rates, or only to time if wage rates are unchanged), which feeds into the composite input cost equation to producers by sector and also into the consumption equation to consumers by commodity This ultimately affects both the composite cost of production by industry and the consumption access index in the economic migration equation.
Accessibility Cost Savings n n Includes the following aspects u Access to more diverse consumer goods and services by households t This affects economic migration by making a region more or less attractive u Access to broader array of intermediate inputs by employers Adjusted by changes in VMT and VHT between and within regions
Accessibility Costs The EDFS-53 Connection: • • Accessibility costs affect the effective distance in the intermediate input access index, which reflects a price elasticity of demand (price is sensitive to distance) and which feeds into the moving average commodity access index. The commodity access index feeds the composite input cost equation and the consumer access equation, ultimately affecting both the composite cost of production by industry and the consumption access index in the economic migration equation.
