ITS IN WORK ZONES
• Work zones create congested conditions
• Often unexpected (mid-day, night)
• Coincides with high truck travel
• Apply ITS to mitigate work zone crashes
• Has evolved significantly in recent years
• Reliability
• Capability

WORK ZONE ITS GOAL
• Provide the right information
• to the right people
• at the right time
• to improve driving decisions, behaviors, and outcomes
• The challenge is proper application to meet user needs

SAMPLE ITS WZ APPLICATIONS
• Speed management
• Travel information (en-route / pre-trip)
• Over height detection
• Automated ingress/egress warnings
• Intrusion alarms
• End-of-queue warning systems
• Dynamic lane merge
• Variable speed limit
• Ramp metering

KEY IMPLEMENTATION ITEMS
• Define the key question(s)
• Determine stakeholders
• Identify user needs
• Identify potential solutions
• Understand operational scenarios
• Track performance

I-35: BACKGROUND
![Page 8: Robert Brydia Project Lead, I-35 Traveler Information During Construction Texas A&M Transportation Institute WORK ZONES & LARGE TRUCKS THE CENTRAL TEXAS.](https://reader030.fdocuments.us/reader030/viewer/2022033105/56649f395503460f94c55ad1/html5/thumbnails/8.jpg)
I-35: BACKGROUND
• Key Questions:
• What are traffic conditions like now?
• What will traffic conditions be like on any portion of my drive?
• Where might I be delayed by work zone lane closures?
• Scenarios:
• Normal Operations
• Lane Closures in Construction Zone
• Incident Event Impacting Lane Closures
• End-of-Queue Operations

I-35 IMPLEMENTATIONS
• Corridor wide ITS equipment base – solar / cellular
• Comprehensive traveler information
• Travel time monitoring and display
• Lane closure tracking
• Lane closure delay projections
• End-of-queue warning systems
• Event analytics
• Contractor coordination
• Construction delay forecast
• Social media

I-35: SAMPLE RESULTS
• <5% of closures resulting in delays more than
30 minutes (+2800 closures to date)
• 87% think information is nearly always accurate
• 62% have changed plans based on the information
• 18-41% reduction in crashes over what would have occurred if EOQ systems not in place

I-35: CONNECTED VEHICLES – LARGE TRUCKS
• Industry cooperation
• Fleets embrace technology / information
• Over represented in crashes
• Partnered with USDOT FRATIS work efforts
• Move beyond drayage to corridor optimization
• Pre-trip planning for routes / loads
• Locational based awareness of:
• Closures, Delays, Queues, Incidents, Speed Reductions
• Audio alerts / voice interaction
• Independent evaluation
