Project Objective – Application of ATM/ICM strategies to facilitate dynamic transportation network management based on prevailing traffic conditions

Context – Very heavy vehicular traffic both east and west bound during on and off-peak periods – rated as the 2nd highest congested network in the Nation (TTI Mobility Rep)

Technology Applications - Active Traffic Management (ATM) and Enhanced Traveler Information• VSL: speed limits are dynamically changed based on observed traffic conditions• Queue Warning: dynamic message signs inform travelers of approaching queues/bottlenecks• Hard Shoulder Running: lane control signs manage the use of shoulders as a travel lane

ICM Nodal Information - Enhanced corridor-specific traveler information, such as real-time transit and parking information, and travel times. Provide parking availability via dynamic message signs along I-66. Park-and-ride lots to be retrofitted with advanced parking management system (APMS) which would track parking space availability and communicate directly with the parking information signs

Dynamic Network Management - The provision of real-time transit information in tandem with real-time traffic conditions would allow commuters to make informed modal choices based on prevailing traffic conditions. Proposed enhanced corridor specific traveler information system would incorporate real-time transit information from transit providers that operate along I-66 into VA511

Connected Vehicle Test Bed - Outfit VDOT and transit vehicles with on-board equipment to support testing of various Connected Vehicle technology application (pavement assessment, SPat, safety). Planned deployment of Connected Vehicle roadside equipment (RSE) infrastructure (Pooled Fund Study)

I-95 ICM VisionApplication Concepts

Integrated Corridor Management (ICM) and ATM/HSR/Q-Warning Systems, Connected Vehicle (CV)

Treatment for HOV Lane TerminationsProblem: Bi-directional HOV lane creating large vehicle queues at its terminations and hazardous situations for drivers when they are un-expectantly encounteredSolution: Deploy hazard detection and warning system at both HOV termination locations. Queue warnings will be relayed through variable message signs along with mile marker location of the queue.

Real-time Inclement Roadway Warning SystemProblem: Hazardous weather related situations for drivers when they are un-expectantly encounteredSolution: Real-time inclement roadway warning system employing weather sensors at critical locations will relay hazardous information to approaching drivers including high-wind and frozen roadway conditions

Technologies for Optimal Multimodal Route SelectionProposed technologies focus on optimizing the roadway network capacity through effective route decisions. Suite of technologies will monitor travel times for each multimodal option from a given location – Information at all ICM nodes such as transit stations, park and ride locations, and truck related elements - overnight parking availability, height and weight restrictions, and roadside inspection stations

Connected Vehicle Ready Proposed technologies produce data elements used within IntelliDrive - travel times, parking availability, and stopped queue ahead are applications envisioned for IntelliDrive.

ICM Project Development Activities

ICM Applications

• Multi-Modal Travel Time Information• Pre-trip, en-route multi-mode travel time information

(roadside signs and VA 511)• End-to-end user-centered trip tool based on updated VA 511• Address road, transit options and available parking should

transit, carpool or slugging option be considered by traveler

• Real-time Parking Management and Guidance• Park-and-ride space, guidance information (VDOT and

transit parking facilities) where travelers have two or more options relative to parking and either transit or carpooling / slugging

• Present comparative travel time information for transit options (including next bus / train departure) along with parking space availability.

• Use roadside signs and add functionality to VA 511

Emphasis Areas

Traveler Information-Related Packages Corridor-wideBuild on 511 / current rideshare initiativesPre-trip orientationEncourage mode shift, moves from SOV to HOV and transitEntire investment could qualify as a TMP-related offset

Operations-Related Packages Segment-based (but includes central hardware/software)Infrastructure-orientedEn-route orientationBenefits to various modesTMP-related offsets could be at least $3.96M of above

Project Location - critical link in transportation network in Hampton Roads area connecting largest ports on the east coast, large military installations, and numerous recreational attractions

Context - Heavy vehicular traffic traveling in and out of the region via the Hampton Roads Bridge Tunnel (HRBT) connecting Southside (Norfolk, Virginia Beach, Chesapeake) to the peninsula (Hampton, Newport News, Williamsburg) resulting in congestion and long queues at the approaches to the HRBT

Technology Applications - The project will deploy technologies to address two common contributors to congestion - over-height vehicles and sudden onset of queuing, primary cause of congestion and often evident on the approaches to Tunnels, Movable Bridges, Ferries, etc, integrated traveler info

Over Height Detection System – Deployment of CB override transmitters upstream of the approach to the westbound tube of the HRBT to alert trucks of the height restriction at HRBT at a sufficient distance so that they can divert to another route

Active Queue Warning System will be installed to alert motorists of stopped or slow moving traffic ahead so that they can reduce speed and avoid making abrupt stop when the end of queue is reached by providing real-time information at points where they can divert to other routes

Technologies for Optimal Multimodal Route SelectionProposed technologies focus on optimizing the roadway network capacity through effective route decisions. Suite of technologies will monitor travel times for each multimodal option from a given location – Information at all ICM nodes such as transit stations, park and ride locations, HOV, etc

Dynamic Route Guidance at decision points to allow drivers particularly non-local who are not familiar with the road network on potential diversion routes to act on information provided

VDOT’s Vision for Advancing Operations

• ATM, ICM, DMA, Connected Vehicle Technologies are becoming Core Elements of VDOT’s Role in Road Operations

• These concepts and technologies are to address Congestion and Safety Issues in both Urban and Rural Sections of the Roadway System

• Recurring and Non-recurring Congestion is the major focus • Weather related aspects - Fog, Wind, Ice, etc are the focus

• I-66 is a Good “First Location” in Northern Virginia for ATM technology application followed by other potential locations statewide

• Integration of Modal Operations and application of emerging Technologies and Tools to address Safety & Mobility issues
