Programs

The programs used to complete this project are Microstation/InRoads, Synchro, VISSIM, SSAM, VGG Annotator, Anaconda, Python, Visual Studio Code, PeMS, Excel.

Microstation/InRoads

MicroStation is a CAD software platform for two- and three-dimensional design and drafting, developed and sold by Bentley Systems and used in the architectural and engineering industries. It generates 2D/3D vector graphics objects and elements and includes building information modeling features.

Synchro

Synchro is a macroscopic analysis and optimization software application. It supports the Highway Capacity Manual's for signalized intersections, unsignalized intersections, and roundabouts. Synchro also implements the Intersection Capacity Utilization method for determining intersection capacity.

Synchro was used to analyze the level of service (LOS) within all three new intersection designs including the existing design to compare the LOS and decide which design would fit best in the site location.

VISSIM

PTV Vissim is a microscopic multi-modal traffic flow simulation software package.

PTV VISSIM was used to model the I-215 freeway and its on/off ramps from the University Pkwy interchange to the Devore Rd interchange. This model was then used to calculate SSAM.

SSAM

The Surrogate Safety Assessment Model (SSAM) is a software application developed to automatically identify, classify, and evaluate traffic conflicts in the vehicle trajectory data output from microscopic traffic simulation models. The SSAM also has built-in statistical analysis features for conflict frequency and severity measures that can aid analysts in the design of safe traffic facilities.

VGG Annotator, Anaconda, Python, Visual Studio Code

These programs were used to aid the execution of computer vision in training to identifying certain annotated objects, learn the annotations, and automatically detect certain types of objects on the road, such as road stress, vehicles, and lane markings.
