From this…. To this….

I-35 Reconstruction Project

Construction – South of Waco

+40 miles

Projects 1B, 1C, 2B, 3A1, 3A2, 3B

Significant milestones to meet

Sections complete 2016 - 2018

ITS infrastructure being moved to permanent condition as sections are complete.

I-35 Reconstruction Project

ITS Infrastructure – Bluetooth

43 sites on I-35 throughout WAC Meets FTW, DAL, AUS

infrastructure Several thousand matches per

day at most sites

Used for: – Travel times – Incident analysis – Daily operations report – Corridor delay

4 year data archive

7

I-35 Reconstruction Project

ITS Infrastructure – Wavetronix

19 sites on I-35 Bi-directional counts and

classifications

Used for: – Lane closure impact assessment – Projections of least impact – End-of-queue analysis

4 year data archive

8

I-35 Reconstruction Project

ITS Infrastructure – CCTV

18 CCTV on I-35 – 17 PTZ

Combination of CCTV / VIVIDS on alternate routes

Used for: – Traveler information – Real-time map – Support for incident management

50 total camera views now available in Lonestar

ITS Infrastructure – Transition to Permanent

10

Move from this…. To this….

I-35 Reconstruction Project

ITS Infrastructure – Alternate Routes

Alternate Routes – 56 sites on key alternate routes

• Bluetooth • CCTV (PTZ and VIVIDS intercepts)

Used for: – Comparative travel times

• Loop 363-Temple / Loop 340-Waco – Traffic conditions during incidents – Real-time map

Status: – 37 sites installed / 19 remaining

11

I-35 Reconstruction Project

ITS Infrastructure – Integration to Lonestar

Operations Focus – Complete Lonestar integration 2011 – WAC supported by special TRF implementation

– Lonestar enhancements • WAC PCMS needs • WAC field infrastructure

– C2C travel time message injection from TTI • Data processed by TTI

2015 – WAC moved to FTW – CCTV integration – Naming conventions and statewide website enhancements – Coming soon Lonestar produced travel times

12

I-35 Reconstruction Project

Initiatives – Traveler Information

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?

Initiatives – Travel Times North of Waco

Use permanent DMS infrastructure in completed sections

Utilize PCMS elsewhere

Travel times computed by Lonestar

Bluetooth sensors feed both TTI and FTW

End of October, 2015

I-35 Reconstruction Project

Initiatives – Construction Delay Forecast Signs

System predicts short-term delays due to construction

Requires real-time data from – End-of-queue – Bluetooth – Wavetronix

Algorithm varies greatly when lane closure timeframes vary from scheduled times

Implementation cancelled

15

I-35 Reconstruction Project

Initiatives – Comparative Travel Times

Supports alternate routes around Temple and Waco

Initially conceived as PCMS basis, now permanent installations

Utilizes Bluetooth infrastructure

Building software

Doing field site investigation and deployment

Solar powered

I-35 Reconstruction Project

Initiatives – Current Delay

Supports on-going construction between Belton and Waco

Utilizes Bluetooth infrastructure

Correlates to delay on real-time map

Doing field site investigation and deployment

Solar powered

January, 2016

17

I-35 Reconstruction Project

Initiatives – End-of-queue warning systems

More than 300 deployment nights Specialty deployments

– DPS investigations – Semi-permanent locations – Waco 6-bridge package

TxDOT pioneered approach / Several states now following and looking at alternative contracting

Key is assessment / business rules

18-41% reduction in crashes over what would have occurred if EOQ systems not in place

18

I-35 Reconstruction Project

Initiatives – Incident Messaging

Added alternate/detour routes – Alternate – suggested – Detour – mandated – Determined by TxDOT based on field conditions

Routes suggested automatically by system Routes plot on real-time map Pre-set text based driving directions New icons Downloadable graphics Works on both smartphones and desktops

19

I-35 Reconstruction Project

Initiatives – Traveler Information Outreach

Lane closure email notices – Over 4,000 subscribers

Incident messaging – Nearly 2,400 subscribers

Real-time map – Corridor delay – Detour routes – Alternate route conditions

Twitter feeds – 6.2M impressions – Two new feeds coming

• Lane closures • Incidents
