Draft Release Notes for 1.1
Packaged versions of the VisionEval framework are provided as .zip files. Each has an installation .bat file for Windows to automatically prepare the R environment.
These installers are packaged for R versions from 3.6.1 to 4.0.1.
-
A multi-modal alternative implementation of the metropolitan model VE-RSPM is now available. This is an alternative to the
VETravelDemand
which allows users to assess impacts on multimodal trips. For more information on theVETravelDemandMM
module, implemented through the newVERSPM_MM
model, see this reference (vignette) and this publication from Prof. Liming Wang for more details. -
Safety Module has been added to
VETravelPerformance
, which adds functionality for users to calculate the safety impacts of the scenarios being evaluated. See [ !! Update this link after PR closed !! ] here for more details. This has been implemented for both VE-RSPM (TODO) andVERSPM_MM

VE-Reports
-
VE-State
- Install one of the supported R versions using its default options (R 3.6.1 to 4.0.1). Make sure to leave the box checked that offers to add R to the Windows registry.
- Download the corresponding installer .zip file
- Unzip the downloaded installer into an empty folder of your choice
- Double-click “VisionEval.Rproj” (this is the standard entry point – use it every time to start VisionEval)
a. If VisionEval has not run before, the batch file and associated script will set up a few pointers and the convenience functions (see below) b. Otherwise, it will move straight to step 5.a below
A command window will briefly appear followed by one of these: a. RGUI with the “Welcome to VisionEval!” message (you’re good to go) b. Your default browser pointing at the R download page (if you forgot to do step 1 or if you picked the wrong version) – just redo step 1 or steps 2/3 to get them consistent
The previous instructions for launching VEGUI, VERPAT, and VERSPM. remain the same.
a. vegui() starts VEGUI b. verpat() runs VERPAT c. verspm() runs VERSPM d. verspm_mm() runs VERSPM_MM (new multi-modal version of VERSPM) d. Note that there’s no helper function to run VESTATE from the command line yet – that will be added to the installation in a future release. You can just setwd() to the VE-State folder under “models” and then source(‘Run_Model.R’).
