A-1 The Freight Trip Generation (FTG) software applies FTG models developed by the Rensselaer Polytechnic Institute (RPI) at the zip code and 2-digit NAICS code levels. This software is bro- ken up into three modules. The first module preprocesses the âCounty Business Patternâ data obtained from the Bureau of the Census and generates a database with information at a zip code and 2-digit NAICS code level. The second module applies the FTG models and produces estimations of freight trip attraction (FTA) and production (FTP). Finally, the third module allows modifying the coefficients used in the estimation of FTG models. Advanced features in the software include applying four types of models and the option of selecting a set or a range of zip codes to be analyzed. This software is available to download from https://coe-sufs.org/wordpress/ftgsoftware. The balance of this Appendix presents the user manual for Version 3.1.

Freight Trip Generation (FTG) Software A-3 Database Information Download County Business Patterns Data, for the year you need. File type: âComplete Zip Code Industry Detail Fileâ Website: http://www.census.gov/econ/cbp/download/ Open the ï¬le in WordPad and save it as text ï¬le with an appropriate name, which would be used for Zip Code Business Pattern Input Data. Make sure the data corresponds to Zip and NAICS code and that it comes in a single line. Freight Trip Generation Estimator Home Page Purpose: This is the home page, which breaks up the program into three parts. 1) The ï¬rst part of the program is the Zip Code Business Pattern Input Data, which takes in information from the raw database to reformat the text ï¬le. 2) The second part is the Freight Trip Generation (FTG) Models, which uses the saved text ï¬le from the ï¬rst part to estimate FTG using one of the four models the user can select. 3) Module 3 is used to modify the default FTA and FTP coeï¬cients, which are used when estimating the FTG Models 1 2 3
A-4 Improving Freight System Performance in Metropolitan Areas: A Planning Guide Module 1: Zip Code Business Pattern Input Data Preparation Purpose: Takes the information from raw database and generates a new database containing only NAICS 2 digit level information for which âFreight Trips Generationâ can be estimated. The data corresponding to 2 digit NAICS code is saved as new text ï¬le to estimate FTG in further steps. Process: 1. Load File: Input the raw database so it can be pre processed by clicking the load ï¬le button and then browse for the saved raw database and open the input ï¬le saved from WordPad. 2. Save File: Need to save a ï¬le that would be exported from the program by clicking the save ï¬le button and then enter an appropriate ï¬le name (the default extension for saving the exported ï¬le is .txt, so you do not have to add it in the save dialog box) 3. Generate Database: After loading and entering the appropriate ï¬le names when you click âSave Fileâ, click on the âGenerate Filtered Databaseâ button to run the program and create a new text ï¬le with pre processed data. 2 3 1
Freight Trip Generation (FTG) Software A-5 Module 2: Freight Trip Generation (FTG) Models Purpose: To estimate the Freight Trip Generation Models.(FTG) FTG is the summation of Freight Trip Attraction (FTA) and Freight Trip Production (FTP) models. The output of the software will include two new columns added to the ï¬le loaded: FTA and FTP. Run any one of the four diï¬erent types of models in the program to calculate and analyze data depending on what you want to analyze. Process: A. Load File: Input the preprocessed database so it can generate freight trips by clicking this button and then browse saved output from preprocessing. B. Save File: Need to save a ï¬le that would be exported from the program by clicking this button and then enter an appropriate ï¬le name (the default extension for saving the exported ï¬le is .txt, so that you do not have to add it in the save dialog box). C. Select a Type of Model: This drop down menu is used to select which model to apply in the program. The equations available in the FTG are as follows: 1. Independent FTA and FTP This a default model in the program, which calculates FTA and FTP, it creates two new columns for each line of output in a new text ï¬le 2. Binary Logit Model Outputs a corrected FTP by calculating the probability from an equation that depends on the NAICS code and FTA and multiply it by the FTP 3. Simple Shares Outputs a corrected FTP by using a default probability value that depends on the NAICS code and multiply it by FTP 4. User Deï¬ned Outputs a corrected FTP by using a probability value you would input in the text box below the drop down box and multiply it by FTP D. Probability Value: Only applies for the User Deï¬ned model, where you have to input a probability value. E. Assume FTA and FTP are Equal to One Per Establishment Checkbox: If the FTA and FTP are equal to zero then FTA and FTP are equal to the establishments F. Use Custom Coeï¬cients of FTA and FTP: This allows you to input your own custom FTA and FTP coeï¬cients to use for the models, instead of using the default coeï¬cients. Read âInput Custom FTA and FTP Coeï¬cientsâ for more information. G. Use Zip Code Filter: Allows you to add a zip code ï¬lter to specify which zip codes the user wants to analyze (for more information read page A-6)
A-6 Improving Freight System Performance in Metropolitan Areas: A Planning Guide H. Input Custom FTA and FTP Coeï¬cients: For uploading custom coeï¬cients text ï¬les, so the program will use these coeï¬cients rather than the default ones. Read âInput Custom FTA and FTP Coeï¬cientsâ for more information. I. Run FTGModels: This will run the program and output the calculations Zip Code Filter Purpose: This ï¬lter is a useful tool to be able to select and analyze certain Zip Codes. Listed below are diï¬erent methods you can use to ï¬lter information using Zip codes: Use a Custom Zip Code Filter Enter a range of Zip Codes to ï¬lter Analyze by state 1. Custom Zip Code Filter: You are able to import the provided zip code list or a custom zip code list by clicking the load custom ï¬lter button. This custom zip code list must be a text ï¬le and have the same format as the example below, with commas and spaces dividing the zip codes and the words âZip A B F E C G H I D Codesâ at the beginning of the document.
Freight Trip Generation (FTG) Software A-7 2. Select a State to Analyze: Where you are able to select any of the 50 states from the drop down list and the program will only analyze the Zip Codes that are in the provided state you have selected. 3. Range: This function allows to output database corresponding to zip codes between the ranges that you have entered and by clicking the âenter the rangeâ button, so the program knows you want to use the range function. Enter the min and max values and there is no need to include the zeroâs at the beginning of the zip code. For example if a value you want to input is â00640â, you should just input 640. 4. Reset Filter: Resets the ï¬lter to the orginal settings. Module 3: Modify Default FTA and FTP Coefï¿½icients Purpose: To be able to modify the default coeï¬cient values, which are used in Module 2. This allows the user to make corrections to the coeï¬cients in a seamless way. You are able to add and delete coeï¬cients from the default values, allowing you to modify and use it in Module 2. 2 1 3 4 A.

A-10 Improving Freight System Performance in Metropolitan Areas: A Planning Guide Initiative Selector The Initiative Selector is an HTML webpage that, for a given set of inputs, return suggestions of potential initiatives that could be implemented for a given problem. The Initiative Selector can be found at http://coe-sufs.org/wordpress/InitiativeSelector/. Figure A-1 shows an example screen from the Initiative Selector. On the left side of the screen there are three categories a user can choose from: (1) Nature of the Problem, (2) Geographic Scope, and (3) Problem Source. The user can select multiple choices for each criterion. As the user enters their criteria identifying the problem, the table in the center of screen is populated with possible initiatives that could be used to solve the problem, along with some key identifiers about the initiative, such as the investment level, length of time for implementation, risk of unintended consequences, and the group and sub-group the initiative belongs to. Figure A-1: Sample output from the Initiative Selector tool Consider the following examples: 1. A neighborhood in an urban area has a large concentration of restaurants and retail establishments (mixed large and small). Currently, the area experiences a high level of congestion due to the number of deliveries made, and delivery vehicles double-parked. â¢ Initiatives suggested (for a Congestion problem, impacting an Area, and produced by Urban Deliveries) are: urban consolidation centers, time slotting of deliveries/pick-ups for large traffic generators, staggered work hours program, and mode shift program. 2. A large volume of freight traffic generated at City A travels to City B but has to cross City C. The traffic uses corridor XYZ which passes through City C. As a result, City C is experiencing congestion due to this through traffic. In addition, the traffic is damaging the city roads.
Additional Information A-11 â¢ Initiatives suggested (for a Congestion problem, impacting a corridor, and produced by Through traffic) are: Ring Roads, Acceleration/Deceleration Lanes, New and Upgraded Roads 3. An intersection in a city has a poor level of service due to a high volume of large trucks. The intersection was designed before a number of warehouses and manufacturing facilities expanded operations. Quite often, these trucks hit utility poles and create unsafe situations â¢ Initiatives suggested (for a Congestion problem, impacting a point, and produced by large trucks) are: removal of intersection constraints, Truck Routes, New and Upgraded Infrastructure These examples demonstrate how the Initiative Selector can lead to a range of sensible recommendations. Obviously, further planning, stakeholder engagement, economic and engineering studies are needed to identify the best way(s) to proceed in any given situation. The alternatives identified using the Guide must be subjected to a rigorous process of vetting and analysis by all key stakeholders, which will provide feedback concerning the relative worthiness and effectiveness of the alternatives, and possibly additional initiatives to consider. Evaluation Matrices for Public Sector Initiatives This section presents a decision matrix for the identified public sector initiatives proposed in this Planning Guide based on inputs identified in Section A. The key inputs to produce such matrices should at least include: â¢ Geographic scope of the problem: This output should define the area(s) where the problem is taking place, which will help define the scope of the potential public sector initiative, such as: citywide, area, corridor, or a point in the city. Again, when defining the geographic scope, it should be recognized that supply chains often interconnect wide geographic areas. â¢ Main objectives to be achieved: It is necessary to clarify the nature of problem, and define corresponding objectives, such as reduction of congestion, pollution, and conflicts between truck activity and other users. â¢ Key constraints: The analyst should have a preliminary estimate of the financial, time, and institutional constraints to which the initiatives will be subject. â¢ Root causes of the problem: The analyst must confirm that the problem is indeed produced by freight activity, and determine which segment of the industry is creating the situation, such as: all or through traffic, large traffic generators (LTGs), urban deliveries, large trucks, or specific industry segments. It is also important to define the time-duration of the problem, such as during: a peak hour, a peak period lasting several hours, daytime, nighttime, or an entire 24-hour period. As discussed previously, identifying the sources and duration of the problem may require further analyses involving freight-trip generation techniques, traffic counts, or interviews with key stakeholders. The more thorough this analysis, the more likely it is that appropriate solutions can be identified. Based on these inputs, a preliminary set of potential initiatives could be identified by scanning Table A-1 and Table A-2, which show summary matrices of the wide spectrum of initiatives.
