Which opens a new screen asking the user to choose a file name and its path. Two new spreadsheets willīe created: âPartial Costsâ and âTotal Costs.â To save the results, click on the âExportâ button, To calculate vehicle operating costs, click on the âRunâ button. Delete any value in the âPercentageâ column. If the traffic distribution is different for each scenario, click on the âTraffic Distributionsâīutton to open a new spreadsheet and provide the distributions in each row. To take into account traffic, input the total vehicle miles traveled (VMT) and the traffic distri-īution. I = Index for VOC components (fuel consumption, tire wear, and repair and mainte-Īt the network level, a grade of 0% and a superelevation of 0% are reasonable assumptions toĬalculate VOC savings unless there is a change in the radius of curves or grades. The general algorithm for estimating vehicle operating costs at the network level is: The variables used to predict consumption rates of each VOC component include: Three components are included in cost calculations (fuel consumption, tire wear, and repair The VOC model calculates vehicle operating costs based on traffic and highway conditions. You shouldĬhoose an option from each section and click on the âRunâ button, which will open the main Levels) and unit system (i.e., US customary units or International System of units). It consists of two main sections: analysis levels (i.e., project or network This is the starting screen when no proj-Įct is currently open. For ExcelĢ007, you should go to the Developer tab and select âMacro security.â Figure 2b shows how toĬhange the security level in Excel 2007 and up.įigure 3 shows the home screen of the VOC model. Or âLow.â Figure 2a shows the path to follow to change the security level in Excel 2003. To make sure that the software is running, the security level for Excel must be set to âMediumâ You will alsoīe able to see an example of project-level analysis data and the data collected as part of NCHRP Is unzipped, click on the âVOC Moduleâ Excel spreadsheet to launch the program. You will need to unzip the file to a preferred location on the hard drive.

Then, to install the software, click on the âVOC Module Setupâ link in the installation wizard Follow the steps to copy the files necessary for the software to work. Plete the process, click first on the âMATLAB Component Runtime Installerâ link (Figure 1). Once the installation kit is launched, the installation wizard will run automatically. Microsoft Excel 2003 or more recent is required. The VOC model is a Microsoft Excel file with macros.

While the VOC model should run on any system from the past several years, the following This document is to describe all software operations. Ses have been performed, you can export a report of the results of any analyses. EntireĪnalysis projects can be saved, which preserves user information and analysis inputs. For projectĪnalysis, profiles can be imported in text format and the model will calculate the IRI. (IRI), mean profile depth (MPD), and pavement type) are the input to the model. For network analysis,ĭata for traffic, environmental, and pavement conditions [e.g., international reference index You to calculate vehicle operating costs at the network and project levels. The vehicle operating cost (VOC) model is an engineering software application that allows Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.
