Slide 2: What is a Paraprofessional

Paraprofessional–

An individual supporting a professional in fields such as education, engineering, healthcare, and law.

A paraprofessional may be required to demonstrate knowledge and skills through certification, education, and/or experience.

Paraprofessionals are normally under the responsible charge of a licensed professional and may be assigned levels of responsibility commensurate with their knowledge and skills.

Slide 3: What is a TSMO Paraprofessional

A TSMO paraprofessional is a position supporting the management and operations of transportation infrastructure.

A TSMO paraprofessional may exert a high level of judgment in the performance of their work.

TSMO paraprofessionals can comprehend and apply knowledge of basic engineering principles in the solution of broadly defined TSMO problems at a cursory level.

TSMO paraprofessionals provide traffic management center operations services and a variety TSMO field services.

Work Zone Technology Innovations

Neil Boudreau
Assistant Administrator for Traffic & Safety
MassDOT – Highway Division

Slide 25: Why make Works Zones “Smart”?

Introduction of ITS (Intelligent Transportation Systems) into the work zone provides:

Improved communication for motorists
Reduce driver distraction
Increase mobility
Worker Safety Measures

The future of Work Zone Innovations

Solution-Based Work Zone Technology
Digitally Connecting Work Zones

Slide 26: Examples of Innovations in Work Zone Safety

Slide 27: Vehicle Queue Warning Systems

Good for remote/off-peak construction

Used to alert motorists of slow or stopped traffic before they reach the back of queue
Helps to prevent rear-end crashes before they happen

Slide 28: Dynamic Merge Systems

Helps to dynamically manage traffic

Early Merge: Light traffic; encourage aggressive drivers to merge into the open lane sooner than they would
Late Merge: Effective for higher volumes of traffic where the congestion and backups are expected

Slide 29: Portable Traffic Signals

Many states use portable traffic signals to support work zone safety and mobility - but the market is getting smarter!

Use Video Detection

Remote connection to message signs
Countdown timer to help motorists

Slide 30: Variable Speed Limit Systems

Allow DOTs to dynamically reduce speed during active construction and when workers are present

Uses beacons to actively show to the motorist that work is going on

Slide 31: Connected Arrow Boards

Broadcast that road work active and what lanes are being closed – helps with mapping services

Now can monitor where all the active construction work zones are happening

Slide 32: Digital Mapping of Work Zones

Use Work Zone Location Sensors to digitally map the GPS location, where work zone begins and ends, and direction of travel

Data can be absorbed by traffic service providers to give improved guidance to approaching motorists
