Traffic Analysis Tools

Traffic Analyses are performed to assess existing and future operations of an intersection, interchange, or corridor segment

Analysis methods include both static calculations and microscopic simulations

Used for all project planning, design, before/after studies at SHA

Sample Traffic analysis Tools/ Applications

• Critical Lane Volume (CLV) • HCS+ • TSIS/ CORSIM • Synchro/ SimTraffic • VISSIM • TRANSMODELER • Others…

HIGHWAY SAFETY MANUAL


Highway Safety Manual

• 2010 - 1st Edition AASHTO publication

• Provides methods to perform transparent, efficient and measurable safety analyses.

• Consists of 4 parts across 3 volumes:

• Part A – Introduction, Human Factors &

Fundamentals

• Part B – Roadway Safety Management Process

• Part C – Predictive Method

• Part D – Crash Modification Factors

Nominal Safety Substantive

Safety

Examined in reference to compliance with standards, warrants, guidelines and sanctioned design procedures

The expected or actual crash

frequency and severity for a

highway or roadway


• NCHRP 17-50 lists leading states implementing the HSM:



• No federal mandate, requiring use of the HSM.

• Some states are beginning to make this

mandatory…

• MoDOT will be requiring HSM analysis for projects with

Design Exceptions.

• Maryland’s State Highway Administration is

currently working with the National Transportation Center at Morgan State University to develop

local calibration factors.

• Initiating a planning-level pilot project on the

eastern shore… US 50 through Easton.



• Current capabilities include:

• Future capabilities • NCHRP 17-45 | Freeways, Ramps & Interchanges

• NCHRP 17-58 | 6-Lane and 1-Way Urban & Suburban Arterials




• Examples:

• Kansas DOT predicted the

safety benefits of adding

and extending passing

lanes to portions of US 50

• Illinois DOT used HSM

analysis to help reduce

roadway departure

fatalities by over 30%.



• Florida DOT HSM Case Study on S.R. 574 (Tampa, FL)

• Right-of-Way cost savings of $1.6M with 5 lane TWLTL

option instead of raised median… Cost-benefit analysis

revealed that it was worth spending the extra money on

the ‘safer’ design alternative.

is a suite of software analysis tools for evaluating safety and operational effects of geometric

design decisions on highways.

• Consists of six evaluation modules:

• Crash Prediction

• Policy Review

• Design Consistency

• Intersection Review

• Traffic Analysis

• Driver/Vehicle

VISUALIZATION AND GIS


Visualization 2D and 3D (Carl)

• To give a representation of what will

exist after the road construction is

completed

• Currently we us ESRI, Microstation,

and Blender products to develop

the Visualizations



2D Visualization

of the design file

• Clean up the design file displaying

only the Alignment and Shading file

• Import in the 2011 statewide image

service

• Create the standard title block that

has been approved by SHA


Display Standards Mapping Elements

•Title Block/Border: Light Beige fill- RGB color: 255,245,225; Black border •Title/Subtitle: Arial, black, bold, italicized; Other title block text: Arial black

roadways and their variations

• Create surfaces of proposed roadways

• Export surface triangles of proposed

roadways and existing surface

Blender

• Import surface triangles created with InRoads

• Manipulate vertices and edges of all surfaces’ triangles to create a single smooth surface

• Model existing and proposed buildings, utilities, signs, traffic signals, trees and other plants, pavement markings, etc.

• Create textures in Photoshop and apply textures to all triangles of a model

• Create pathways for traffic simulation

• Create intersection traffic patterns and signal timing

• Export all elements of the model as .x files


SHA 3D Simulation

• Take screenshots for static displays such

as photomatching, or entirely computer

generated images

• Pre-render videos to show at a later

presentation

• Use simulation in real time as part of a

presentation to provide a virtual tour of

proposed project.
