Reports

Overview of Formatted Reports

All model summary reports are stored in the {SCENARIO_DIR}\_reports folder.

There are several reports generated by SERPM 8:

• Input data summaries (SE data summary*.xlsx)
• Overall model summaries (SERPM8_Report*.xlsx)
• Transit ridership summaries (Transit Boarding Statistics*.xlsx; Transit Trip Summaries*.xlsx)
• FSUTMS systems highway evaluation (HEVAL) summaries (HEVAL*.PRN, TRKEVL*.PRN, RMSE*.PRN files)
• Air Quality summary report (AQ*.PRN) and post-processed loaded networks (AQ.*NET)

If the "Summarize Results" option is selected, a comparison network (comp_net.net) is generated with volumes from the base and scenario results.

Finally, an R dataset file (*.RData) is saved that contains the ABM outputs in a combined tour, trip, persons, and household data tables.

A data dictionary of the report networks is provided below

HEVAL Reports

SERPM 8 generates the HEVAL reports as part of the Post Processing application group that is run as the last step in the model. HEVAL is a process originally developed by FDOT - more information on the background and development of HEVAL are available here.

Depending on the run mode selection (see following section), HEVAL reports include the following information summarized overall, by county, and categorized by area type, facility type, number of lanes, and volume group:

• Network statistics (links, lane miles, directional miles, links with counts)
• VMT and Volumes
• Speed comparisons (posted, congested, free flow)
• Volume to capacity ratios
• Road costs (travel time value and vehicle operating costs)
• Safety analysis (accidents by type, property damage, injury by type)

Crash rates used to produce the Safety Analysis summaries in HEVAL are defined in tables in the Inputs\heval\ACC_HEVAL folder.

Subarea

HEVAL produces summaries for the entire region and by each county (denoted with the PB, BO, and MD suffixes). The user may define their own subarea by setting the DetailNet attribute in the highway network to 1. If the scenario key to summarize by subarea (key 1 in above image) the HEVAL reports are generated with "WindowedArea" in the file name.

Road User Costs

The HEVAL reports include calculations of the road users costs through a tabulation of the delay time weighted by travel time values (TTV) and distance traveled by vehicle operating costs. The costs and methodology leverage the research conducted by the Southeast Florida Road and Transit User Cost Study.

Travel time values vary by:

• Person and household attributes (e.g. Income, Age)
• Trip purpose and length
• Trip mode, and time of day.

A derived travel time value has been calculated by car and trucks and time of day to apply to the SERPM 8 highway assignment results.

The travel time values are segmented by cars and trucks and adjusted by time of day (AM, PM, OP) in the Inputs\Highway\Parameters\FTRPTGRP_TTVLkup.dbf file.

Vehicle operating costs are calculated considering the following cost components:

• Vehicle energy consumption (traditional fuel, alternative fuel, and electricity);
• Fuel taxes
• Routine maintenance and repairs
• Batteries
• Tires
• Depreciation
• Finance charges
• Safety
• License and registration

Rates segmented by cars and trucks and by speed are defined in the Inputs\heval\ACC_HEVAL\VOCSpdLkup.dbf file.

The HEVAL report mechanism includes the support to calculate vehicle operating costs and travel time value in model forecast year dollars. To produce costs and value inflated to a future year value, the scenario keys identified by 3 in the above image need to be set to the future year and annual inflation rate (as a decimal, e.g. 0.017 for a 1.7% annual inflation rate). By default, the values are set to the observed CPI inflation rate between June 2010 and June 2015.

HEVAL Report Files (located in the _reports folder)

See the HEVAL tab of the spreadsheet above for references to the HEVAL report files

Air Quality Reports

SERPM 8 generates air quality reports at the link, county, FDOT district, and system level. The following air quality metrics are produced:

• Emissions related to Ozone formation
  • Oxides of Nitrogen (NOx)
  • Volatile Organic Compounds (VOCs)
• Emissions related to Greenhouse Gas (GHG) formation −
  • Carbon Dioxide Equivalents (CO2eq)
  • Carbon Monoxide (CO)
• Particle pollution
  • Coarse dust particles (PM 10)
  • Fine particles (PM 2.5)

Emissions and pollution rates are defined in tables in the Inputs\heval\AQrates folder. The rates are interpolated and extrapolated as necessary to produce estimates of the rates for the specified model year.

Air Quality Report Files (located in the _reports folder)

• Summary Network with emissions and pollution at the link level in grams (AQ_*.NET and AQ_*.DBF)
• Summary Report with emissions and pollution at the county, district, and regional level in tons (AQ_*.PRN)

R Workspace from Reports

The R workspace is also saved in the _reports folder as an *.Rdata file. Loading this file into RStudio provides access to the model outputs summarized in the data dictionary below.
