INTRODUCTION CALINE4 (Caltrans, 1989) is a dispersion model that predicts carbon monoxide (CO) impacts near roadways. Its purpose is to help planners protect public health from the adverse effects of excessive CO exposure. The Caltrans publication, Transportation Project-Level Carbon Monoxide Protocol (CO Protocol) (Garza et al., 1997), recommends the use of CALINE4 when a proposed transportation project fails an initial screening analysis (described in Appendix A of the CO Protocol), and therefore, requires a more detailed analysis. CALINE4 is a simple line source Gaussian plume dispersion model. The user defines the proposed roadway geometry, worst-case meteorological parameters, anticipated traffic volumes, and receptor positions. The user must also define CO emission factors for each roadway link. CO emission factors should be generated with the California Air Resources Board’s EMFAC7f model or CT-EMFAC1, which was adapted from EMFAC7f by Caltrans to be easier to use. (Note that CT-EMFAC modeling requires a similar level of user-effort as CL4.) CL4 is a graphical windows-based user interface, designed to ease data entry and increase the on-line help capabilities of CALINE4. The CL4 setup program is self-contained with both programs (the CL4 interface and the CALINE4 dispersion model), so the user only needs to complete a single installation step. The original CALINE4 executable files are copied to the CL4 program directory. 1.1 INSTALLATION OF CL4 CL4 requires a 486/66 or better PC with 16+ Mb of RAM. CL4 runs with Windows 95 or Windows NT V4.0. To install, CL4 requires approximately 3 Megabytes (Mb) of free storage space on the destination drive. To install CL4 from the Caltrans website: 1. Log in to the Caltrans internet site, http://www.dot.ca.gov/hq/InfoSvcs/EngApps/ and obtain the CL4 installation program. 2. Save the CL4 installation program to a temporary directory. 3. Double-click on the CL4 installation program icon to run the program. 4. Follow the prompts to install. Choose a destination directory for the program files, then click the "Install" button to begin. To install CL4 from floppy disks: 1. Insert the floppy disk labeled “Disk 1”. 2. Run the program, “Setup.exe” from the floppy drive. 3. Follow the prompts to complete the installation. 1 Download CT-EMFAC from the Caltrans web page. 1-2 To remove CL4 from your computer: 1. From the Windows 95 Start menu, click Start|Settings|Control Panel. 2. Double-click Add/Remove Programs. 3. Select CL4 from the list of programs. 4. Click the "Add/Remove" button. 1.2 GETTING STARTED To start CL4, go to the Windows 95 Start menu, and click Start|Programs|CL4. A splash screen will appear briefly. (You may also click <Enter> or the button shown below to hide the splash screen.) ß Hide splash screen. When the splash screen disappears, the first of five data entry screens becomes available and you can begin entering data (Figure 1-1). Figure 1-1. CL4 user interface: Job Parameters data entry screen. 1-3 1.2.1 Create and Save a New Job As you begin to enter data, it is very important to periodically save your work to avoid accidental loss. Create a new file (or “job”) and save your work from the File menu (circled in Figure 1-1, upper left). Click File|Save, then type a name for the job. (Note that the standard file extension for CALINE4 input files is .dat, which CL4 assigns automatically.) 1.2.2 Open a Previously Saved Job Previously saved jobs may be opened from the File menu. Click File|Open, then type (or point-and-click) the name for the file you wish to open, then click the Open button (or press <Enter>). 1.2.3 Enter Data Input devices are available to assist with data entry: data entry fields, radio buttons, drop lists, and page tabs (illustrated in Figure 1-1). Data entry fields allow alphanumeric entries; radio buttons and drop lists permit choices between options; page tabs change views between five data entry screens (more detail in Section 1.5.2). Use the mouse to point-and- click and move between the input devices. Note that Microsoft tool-tip© help is available for many of the input devices; if you rest the mouse pointer over an input device, a text flag appears with guidance. Data on all five data entry screens, listed below, must be complete in order to run CALINE4. • Job Parameters • Link Geometry • Link Activity • Run Conditions • Receptor Conditions 1.2.4 Run CALINE4, View and Save Output Files You may run CALINE4 by pressing the green “Run” button on the Job Parameters screen. Alternatively, you may click File|Run from the CL4 menu. You will be prompted to save your work if you have not already done so, and you will be notified if the data on any of the five data entry screens appear to be incomplete. CALINE4 produces a temporary output text file that is automatically named C4$.out. CL4 automatically invokes the Windows 95 Notepad program (included with Windows 95 installations) and displays the C4$.out text file for viewing after CALINE4 is finished. Click the File|SaveAs command from the Notepad menu in order to save the output file with a different name; otherwise, C4$.out will be overwritten the next time CALINE4 is run. 1-4 In order to view previously saved output files, move to the Windows 95 Start menu and press Start|Programs|Accessories|Notepad. Select File|Open from the Notepad menu; choose the name of the file you wish to open, and press the “Open” button. 1.3 FOR MORE HELP WITH CALINE4 For more guidance than provided by this manual and CL4’s on-line help files, check the Caltrans web page, www.dot.ca.gov/hq/InfoSvcs/EngApps/. 2-1 2. DETAILED USER INFORMATION 2.1 CL4 MENU ITEMS CL4 carries a menu bar with the following choices, File, Edit, View, and Help (see Figure 1-1). With the mouse pointer, click and select the following menu choices to perform the general file management and computing tasks listed below. File |New: Discard all data entries and begin a new job. |Open: Open a previously saved data file. |Save: Save the current data file. |Save As: Assign a new file name and save work. |Run: Run the job based on the current data file. |Exit: Exit CL4. Edit |Cut: Cut selected text or data and temporarily save it in the Windows clipboard memory (shortcut key, <Ctrl>X). |Copy: Save selected text or data in the Windows clipboard memory (shortcut key, <Ctrl>C). |Paste: Copy the clipboard contents to replace selected text, or insert the clipboard contents at the cursor position (shortcut key, <Ctrl>V). View Menu choices switch views to the corresponding data-entry screens: |Job Parameters |Link Geometry |Link Activity |Run Conditions |Receptor Conditions Help The following menu choices will display on-line help and tips extracted from this user’s guide that describe features on the corresponding data-entry screens (shortcut key, <F1>): |Job uploads/s3/ user-x27-s-guide-for-cl4-a-user-friendly-interface-for-the-caline-4-model-for-transportation-project-impact-assessments.pdf
