4 Traffic Congestion $200 Billion per year Decreased fuel efficiency & air quality Increased costs of consumer goods Time, time, precious time Supply chain impacts: Diminishes productivity Increases transportation costs Source: USDOT Congestion Initiative, Federal Highway Administration, 07/2007

5 Congestion Sources Bad Weather 15% Special Events 5% Poor Signal Timing 5% Capacity Constrained 40% Work Zones 10% Traffic Incidents 25% USDOT Congestion Initiative, Federal Highway Administration, 07/2007

6 TxDOT Mission, Vision, and, Policy: safe, effective, and efficient movement of people and freight.

13 Electronic Tolling Systems Purpose: Drive through without stopping or scrambling for cash System Components: 1. Transponder Programmable Power source 2. Lane antenna 3. Lane controller 4. Host computer system

14 Transponder Types Type I: No processing capabilities information is read only hard-wired id number Type II: Updateable area to encode information time and point of entry Type III: Microprocessor enabled - smart tags Communicate to roadside or overhead sensors account balance driver and vehicle information location

15 Transponder Types (cont) Passive: No internal power supply Incoming radio frequency signals detected by antennae Signal powers up tag Limited data storage Semi-Passive: Battery power Respond faster Stronger signal More data storage Active: Connected to vehicle power source Store more information Receive and store information sent by roadside units Much greater range

21 Electronic Toll Collection Other Benefits: Eliminates costs Limits revenue leakage Reduces safety concerns Interoperability

22 Issues Supply chain and freight impacts Big Brother and privacy concerns Infrastructure capacity Interoperability Technology

23 Supply Chain Impacts Freight Growth Freight shaped by globalization of production and logistics System performance challenges tougher as capacity lags demand Public sector infrastructure challenges impact the economy

25 Truck Transportation Supply Chain Changes with RFID Applications New mileage-based or ton-mileage fees More toll roads / truck-only lanes Tighter emissions limits New (e.g. carbon) taxes, and user fees Further workforce regulations Higher productivity equipment

26 Proposed Privacy Legislation Notice and consent to collect personal information Information relevant to services provided Protect individuals' rights to move without being tracked Security of electronic transactions Protect personal information

30 Additional Future Applications Automated crash notification system Enterprise call box OnStar on steroids Electronic vehicle registration Vehicle-to-vehicle communication Vehicle to roadside communication Odometer tolling Vehicle positioning systems Satellite tolling Cell phone tolling More in-vehicle features RFID GPS

31 Automated Crash Notification Systems 433 MHz RFID tag with vibration sensor Attached to guardrails, signs, etc. Detects crashes into tagged roadside objects vibration sensor activates the tag Proprietary protocol transmits ID

32 Vehicle Infrastructure Initiative (VII) Public/Private partnership vehicle-vehicle and vehicle-infrastructure communications wireless network Dedicated Short Range Communication coordinated deployments of communication technologies On all major U.S. roadways

33 Vehicle Infrastructure Initiative (VII) Warning drivers of unsafe conditions, imminent collisions, weather, congestion Proof-of-concept Detroit 2006 and 2007 Privacy issues On-board computers and data
