Software Issues • Managing Licenses across entire

department • Many licenses of software packages

– each change requires action by both agency and vendor

• Some users need access full-time, others only once-twice a year

• Licenses often “change hands” with frequent personnel changes / temporary assignments

• Consider public agency needs • Public agencies need copies of all

software used by private sector to fully complete reviews of submittals

NCDOT Congestion Management Capacity Analysis Guidelines

• Standardize analysis done across the state, both for NCDOT projects and developer Traffic Impact Analyses submitted for driveway permit approval

• Includes: • Alternatives to be studied • Design information • Signal timing requirements • Traffic volume details • Default values • Specific Software Inputs

First developed 2005 Current version 2012 Modifications 2014

Synchro

• Intuitive Graphical User Interface

• Quick Complex Analysis Results

• Easily Coded Coordinated Networks

• Simple Alternative Comparison

• Cumbersome Licensing Structure

5

Simtraffic

• Microsimulation Tool

• Utilizes Macroscopic Synchro Package

• Simple and Quick

• To maximize microsimulation accuracy, the

network should be calibrated.

8

Simtraffic Animation

9

Transmodeler

• Microsimulation Tool

• Also provides macroscopic results

• To maximize microsimulation accuracy, the

network should be calibrated.

• More robust microsimulation tool than

Simtraffic

• Works with TransCAD traffic modeling

software

10

Highway Capacity Software

• Based on the Highway Capacity Manual

• Manual is published by the Transportation

Research Board

• Simple Interface

• No Graphics

12

SIDRA

• Roundabout Analysis


• Gap-acceptance Capacity Model

• Software offers other analysis options

Alternative Design Concepts

Quadrant Left Huntersville

Diverging Diamond Interchange Cornelius

Analysis Challenges • Highway Capacity Manual

Procedures • Developing standards for “apples

to apples” comparison for HCM 2015

• Integration into existing models • Need to “trick” analysis tools to

allow for analysis • Long Term – Develop methodology

to include various design concepts easily

Roundabouts

222 Roundabouts (as of 8/1/2014) • 116 State – including 20 UC • 100 Municipal • 6 Private • 12 Multilane - 10 State (5 UC), 2 Municipal • 1 Removed (widening project)

North Carolina Roundabouts

“Synchro [version 7] should not be used for analysis of roundabouts. SIDRA, HCS [2010], or VISSIM are currently the only acceptable analysis tools for roundabouts in North Carolina.”
