1. Overview 

This memorandum is intended to document the USEPA MOVES based mobile source 

air quality analyses performed by the Ohio Department of Transportation (ODOT) for 

the Akron Metropolitan Area Transportation Study (AMATS) and Ashtabula county 

areas, and by ODOT and the the Northeast Ohio Areawide Coordinating Agency for the 

counties of Cuyahoga, Geauga, Lake, Lorain and Medina in its area. These analyses 

were conducted in support of Ohio EPA’s intent to submit a redesignation request and 

maintenance State Implementation Plan (SIP) 2008 8-hr Ozone NAAQS. 

The designated maintenance area in northeast Ohio for the 2008 8-hr Ozone NAAQS 

includes the counties of Cuyahoga, Geauga, Lake, Lorain, Medina, Portage, and 

Summit; and Ashtabula. 

The inventories include county based, annual totals of Volatile Organic Compounds 

(VOC’s) and Oxides of Nitrogen (NOX) for the years 2011, 2014, 2020, and 2030. 

Latest Planning Assumptions 

These ozone inventory runs meet the latest planning assumption requirement as the 

area remains under the grace period for using MOVES2010 in lieu of MOVES2014. As 

discussed in Section 2 of this report, the travel forecast modeling processes used to 

develop vehicle miles of travel (VMT) for the AMATS and NOACA areas is calibrated 

using the latest population and land use data available and are validated using 

corresponding traffic count data. Currently, the travel demand models are validated to 

year 2005. 

U.S. EPA’s MOVES2010a is used for all mobile source emission analyses with MOVES 

input and output needs being established at various interagency consultation meetings 

and e-mails in January 2016 (See Appendix A). It was also established that annual 

emission estimates would be based on a single-season approach. The emissions 

estimates are expressed in tons per day. 

Finally, the regional emissions analysis includes emissions for Volatile Organic 

Compounds (VOCs), and Oxides of Nitrogen (NOX).

2. Urban Travel Demand Models

NOACA maintains a PC-based regional travel demand forecasting model on the Citilabs 

CUBE platform for use in its urban transportation planning process. This model employs 

the traditional four step modeling process to project existing and future traffic volumes 

and travel patterns on the regional transportation networks. The four step process 

consists of trip generation, trip distribution, mode split, and route assignment. Output 

from the model is link-by-link directional volumes for four time periods: AM peak, 

Midday, PM peak, and Night and is added together to create 24-hour traffic volumes for 

the existing or future regional transportation networks. ODOT ran NOACA’s model for 

this effort. 

The Ohio Department of Transportation (ODOT) holds the transportation model for the 

AMATS area. AMATS prepares and submits networks for its planning area to ODOT. 

ODOT prepares networks for Ashtabula County. ODOT's modeling is also run on a PCbased CUBE platform. 

These models are uniquely suited to perform emission analyses. The modeling process 

identifies growth in vehicle miles of travel and changes in regional travel patterns 

resulting from the projects that are proposed in these areas’ transportation plans and 

programs. 

Landuse and Socio-economic Data 

The areas’ socio-economic model variables reflect the current and expected future 

regional land uses as best known to staff. 

Socio-economic variables were developed for all areas based on 2000 Census data and 

2030 county-level Ohio Department of Development population projections. Minor 

adjustments to 2005 data have been made in an effort to have this data correspond to 

2005 estimates released by the US Census Bureau. 

 

Until new 2010 Census based projections are developed by the Ohio Department of 

Development (ODOD), the current data represents the best available for this effort. 

3. Emission Factor Generation

Using MOVES, emission factor files were generated for 2011, 2014, 2020, and 2030. 

Assumptions for these runs include an I/M program in all but Ashtabula Township. 

Programs and corresponding MOVES parameters were developed in consultation with 

OEPA.

Temperature and Relative Humidity 

Temperatures used for the single season approach are representative of 12 months in 

2006 based on NOAA data from the National Climate Data Center website. The month 

of July was used as the representative month. Data for Cleveland Hopkins International 

Airport (CLE) was used for NOACA’s area. Data for Akron-Canton Airport (CAK) was 

used for AMATS and Ashtabula Areas. To get the correct fomat for MOVES, the data 

was entered into a spreadsheet provided by EPA which was designed to convert 

Mobile6 data to MOVES. The average annual hourly temperature and relative humidity 

distribution profile for Cuyahoga, Lake, Lorain, and Medina Counties can be seen in 

Table 6a. Table 6b portrays the data for Portage and Summit Counties; and Ashtabula.

Source Type Population Source type population is based on a combination of local and MOVES default data. Local data was obtaineMotor Vehicles Motor Vehicle Registrations by county and vehicle type. The MOVES default source type popfrom the national level MOVES inventory runs for each county. OBMV’s vehicle registration data was used as a control total for all source type population and a sub total for 

Bus (42), and School Bus (43). The same data was also used to assign source type population of Motorcycle (54). For the rest of source types 21, 31, 32, 51, 52, 53, 61 and 62, the fraction of each source type from the 

used and adjusted to match up the control total for source type population. Future year source type growth ra

I/M Program 

I/M program information was supplied by Ohio EPA. The I/M program was applied to all 

analysis years for every geography with the exception of Ashtabula County. The I/M 

program MOVES inputs reflect: 

1) ASM 2525 Phase-in Cutpoints, for model years up to 1995 

2) Evaporative Gas Cap Check, for model years up to 1995 

3) Evaporative System OBD Check, for model years 1996 & newer 

4) Exhaust OBD Check, for model years 1996 & newer 

The compliance rate and failure rates are obtained from Ohio EPA and compliance 

factors are calculated. These are applied to Cuyahoga, Geauga, Lake, Lorain, Medina, 

Portage & Summit counties and for all model years. 

Vehicle Age Distribution 

Vehicle age distribution information was derived using ODPS vehicle registration data 

(2009). The data was given to OEPA who supplied a VIN decoder that allowed ODOT 

to create correctly formatted MOVES inputs. A different age distribution file is used for 

each county. Table 9 provides a sample distribution for Cuyahoga County. The 

distributions for other areas can be found in the electronic input submittals. The same 

age distributions were used for all analysis years.

Road Type Distribution 

Road type distribution is based on the ODOT’s 2006 daily vehicle miles of travel 

(DVMT) by functional classification (FC). These inputs vary by county. A sample road 

type distribution input for Cuyahoga County can be seen in Table 10. Cuyahoga County 

does not contain rural road types 2 and 3. The distributions for other areas can be found 

in the electronic input submittals.

Vehicle Type VMT and VMT Fractions

VMT by MOVES vehicle types is subdivided into four sections namely HPMS base year 

VMT, monthly VMT fractions, daily VMT fractions and hourly VMT fractions. For 

NOACA’s counties, HPMS base year VMT was derived by using the converter tool, US 

EPA’s AADVMT Calculator_HPMS.xls. The converter takes average annual daily VMT 

(AADVMT) and generates MOVES input data based on default factors. AADVMT is 

computed by using total daily VMT obtained from travel demand model and fractioning it 

with the MOVES default distance travelled by each source type to come up vehicle type 

VMTs. The same method was used to generate data for other analysis years. 

ODOT uses weigh in motion (WIM) data to develop inputs for the counties it models. 

The inputs for each geographic area can be seen in the supplied input files. Sample 

HPMS VMT for 2006 is provided in Table 11.

Output Emission Factors 

Table 12 shows the first record in a MOVES sample output (rate per distance) emission 

file for year 2006. For any given month, day of week, hour of the day, pollutant, and 

process; the rate per distance varies by road type, and speed bin. Rates per distance 

emissions are applied to link and intrazonal VMT.

4. Post Processing

Total emissions were computed with the aid of several custom programs by ODOT. 

The process uses data on daily and directional traffic distributions as well as more up to 

date volume/delay functions from the 2000 Highway Capacity Manual (HCM). This 

process, described below and illustrated in Figure 4, also uses rewritten code able to 

handle the newer model network formats and MOVES generated emission factors. 

First step (movessource.exe) aggregates the emission factors. Rate per profile and rate 

per vehicle files are combined during this process. The resultant emission factor files 

contain emission factors broadly classified into total vehicles, cars and trucks by 

pollutant, by average speed, road type and hour of day. 

The second step in the the process involves running ODOT postcms.exe to calculate 

hourly link volumes based on the percentage of the daily volume (travel demand model 

output) determined by a link’s facility and area type. Link speeds from the travel 

demand model are not used in the analysis. The speeds are estimated as a postprocess to the model based on HCM methods using a link’s volume-to-capacity ratio 

and link group code. The daily to hourly volume conversion percentages and speed 

tables can be seen in Appendix B. 

The third step (movesnet.exe) uses a combination of the MOVES emission factors and 

the hourly link volumes that are output of the postcms.exe program. The hourly 

volumes are multiplied by the MOVES emission factor for the corresponding hour of 

day, speed bin, and roadtype to calculate emissions for every network link for each 

hour. The final link on road vehicle emissions for the area is the sum of all individual 

link-hour emissions. 

The fourth step, (movesveh.exe), calculates vehicle-based emissions for each source 

type for each hour of the day. The vehicle source type is based on a combination of 

local and default data. The final vehicle emissions for each county are the sum of all 

individual hourly emissions for all vehicle types. 

Intrazonal trips do not get loaded onto the network, so the fifth step in the process 

requires a separate method to account for those trips that use local roads to travel 

within a zone. The movesintra.exe program uses intrazonal trips to estimate VMT using 

the area in square miles and intrazonal trips of each zone. The zone is assumed 

circular and the radius of the circle is used as the average trip length for these 

intrazonal trips. Intrazonal emissions are then calculated by combining MOVES 

generated emissions with estimated intrazonal VMT. The emission rates are the same 

as those used to calculated link based emissions. 

The final step is to summarize link, vehicle, and intrazonal emissions for each county, 

pollutant, and analyzed year. Summary emissions for each pollutant, county, and 

scenario year in northeast Ohio were previously displayed in tables 1-4.

Cleveland Areas 

 

Please forgive me if I do not have everyone that was on the call on this email...please 

route as needed. 

 

We concluded our IAC call in record time...15 minutes! Representatives from NOACA, 

ODOT, OEPA, USEPA, and FHA were on the call. MORPC and LCATS were not on 

the call. Nick from MORPC did call me right after our call ended and I filled him in. If 

you can provide feedback on the minutes by COB 1/17/16 that would be appreciated. 

 

The counties each agency is responsible for regarding the modeling: 

Cleveland: 

Cuyahoga, Geauga, Lake, Lorain and Medina counties: NOACA 

Ashtabula county: ODOT 

Summit and Portage counties: AMATS 

 

Columbus: 

Franklin, Delaware, Licking, Fairfield, Madison, and Knox counties: MORPC 

LCATS doesn’t model 

 

ODOT (Nino) will perform MOVES runs to provide emissions factors to NOACA, 

AMATS and MORPC (MPOs). The MPOS will use the emissions factors in combination 

with the travel demand model to produce emissions in tons per summer day (TSD). The 

process will be documented by the MPOs in a report to be submitted to OEPA along with 

2 disk of the modeling files for each area. 

 

I am assuming ODOT (Nino) will be responsible for both the ODOT and MPO steps 

above for Ashtabula County? Therefore, Nino will need to coordinate with NOACA and 

AMATS in providing the emissions for the final write-up. 

 

Here is the pollutant and year needs for each county: 

 

VOC, NOx (TSD) 

2011, 2014, 2020, 2030. 2020 and 2030 will be budget years. We will once again try to 

accommodate a 15% safety margin for mobile budgets. Once all sector emissions are 

analyzed, OEPA will notify everyone via email of the results and ability to accommodate 

the 15%. 
 

I am proposing the following timeline: 

 

ODOT delivery of data to MPOs: 2/5/16 (3.5 weeks) 

MPO deliver to OEPA: 2/26/16 (3 weeks) 

 

Thanks for your participation, Jennifer

Looks like most everybody except NOACA has responded and the only day that works 

for everyone is January 20 at 1pm EST. So I am hoping this will work for them also and 

we can do them together since we will cover the same information. 

 

I have a bridge line that only holds 18 so if you can all gather at your respective agencies 

as much as possible when you call in that will ensure nobody is left out. 

 

The number is 614-387-7405. 

 

I have also made a correction to the email below which will serve as a rough agenda. If 

anyone wants to email me other topics they would like to cover in advance I’ll include 

them. 

 

Thanks much, Jen

Subject: Interagency Consultation - 2008 Ozone Redesignations for Columbus and Cleveland 

Areas 

 

Hello IAC contacts, 

 

We are wrapping up development of our redesignation request and maintenance plan for 

the 2008 ozone standard for the Cincinnati area. We now would like to move on to 

preparing documents for Columbus and Cleveland areas. It is important we have all 

redesignations in under the 2008 ozone standard with sufficient time for USEPA to 

approve them prior to USEPA making designations under the newer 2015 ozone standard 

(Oct 2017). We will need assistance in mobile emissions inventories and projections for 

these areas. 

 

Here is a summary of the counties with the MPOs/Agencies I believe modeled each 

county last time. Please correct me if I am wrong! And please let me know if I should 

add/remove anyone from this distribution list. 

 

Cleveland: 

Cuyahoga, Geauga, Lake, Lorain and Medina counties: NOACA 

Ashtabula county: ODOT 

Summit and Portage counties: AMATS (data goes to Nino at ODOT for extrapolating 

data for Air Quality) 

 

Columbus: 

Franklin, Delaware, Licking, Fairfield, Madison, and Knox counties: MORPC 

LCATS, ODOT doesn’t model 

 

Here is the pollutant and year needs for each county: 

 

VOC, NOx 

2011, 2014, 2020, 2030 

 

I have also attached the write-up from OKI for the Cincinnati area. We will need 

something similar for your areas also. We also need two disks with all the modeling files 

once finalized. 

 

We will once again try to accommodate a 15% safety margin for mobile budgets. 

 

Thanks much, Jennifer
