15 Intelligent Transportation Opportunity: Open Road Tolling - - In the Early Growth Phase Open road tolling: process for collecting tolls without stopping to pay a toll Innovative toll technologies offer motorists new state of the art highways with increased efficiency and improved driving experiences Federal Signal is positioned to leverage its best in breed PIPS technology offering - PIPS is an important enforcement mechanism in Open Road Tolling Estimated global market for electronic toll collection technologies and services exceeds $5 billion In the US, over 30 states are now planning, building or operating tolls to finance required infrastructure expenditures - tentative financing mechanisms are depleted (e.g., Federal Highway Trust Fund) Tolling is the most effective state and local measure to finance required expenditures (source: National Surface Transportation Infrastructure Financing Commission) Economic and environmental benefits of Open Road Tolling and electronic toll collection Improved traffic flow, shorter commute times, automated collection results in higher net revenue than manual collection, fuel savings, reduced emissions from slowing and stopping v. paying at highway speeds HOT lanes allow toll operators to expand capacity without being required to build more infrastructure Case study for PIPS' leadership position: Denver E-470 toll-way One of handful of fully cashless toll roads in the US. Opened 3Q2009 PIPS and its technology partners reduced number of violations requiring manual review by 2/3 - cost of automated review using PIPS is < $0.05 per transaction v. > $2.00 for manual review

Toll Technologies 16 5. Transaction processing / toll back-office: Manages customer accounts, some customer service interaction. 4. Lane Controller: Transfers information from lane to back office where account billed or bill mailed to customer. Step 1. Vehicle Classification: Determines toll amount by determining "class" of vehicle. 3. PIPS camera / Enforcement function: Cameras take picture of car plates where RFID tag does not pay for toll. 2. Vehicle identification / RFID Tags & Readers: Readers read in-vehicle tags.

17 PIPS: Platform for Public Safety & Transportation Growth PIPS is the leading ALPR technology "ALPR" = Automated license plate recognition Will deploy into existing infrastructure - provide 24-hour monitoring Maintaining valuable database of information - used to manage traffic, enforce laws, identify threats and control access Responding to the trend of law enforcement rapidly becoming an IT based business Interoperability in communications driving federal and state spending Market needs are driving strong PIPS growth Q3 2009: 35%+ sequential order growth and +16% vs. LY PIPS is the most accurate and reliable ALPR solution in the market today D.H.S.
