Page 5Infrastructure and Cities / Mobility and Logistics / Intelligent Traffic Solutions SEPAC® 3.52/4.52 Priority Control At the same time, keeping individual traffic flowing to avoid congestion, which causes a negative impact on the environment, is equally important. Giving high priority to public transportation without interrupting the general traffic flow has been a major challenge for conventional traffic control software in the past. Buses and light rail trains need to stay on schedule to make public transportation an attractive alternative to other means of transportation.

Page 6Infrastructure and Cities / Mobility and Logistics / Intelligent Traffic Solutions SEPAC® 3.51 Enhances Performance of Traffic Signal Control The latest version of the proven SEPAC traffic control software is focused on enhancing performance of traffic signal control for customers who use Light Rail Transit, Bus Rapid Transit and regular Traffic Signal Priority functionality. A new set of features improves the use of partial and full priority, with minimal impact on pedestrian and vehicle traffic. With more than 25 years of developing and testing, SEPAC is an unparalleled traffic signal priority software that enables mobility, safety and a better environment to help improve the quality of life in cities.

Page 9Infrastructure and Cities / Mobility and Logistics / Intelligent Traffic Solutions Modes of Operation SEPAC’s traffic capabilities include five modes of operation that allow for Time of Day (TOD) operations, week plans, time of year or holiday plans, which include: coordination, free and flash functions. Modes include: Standalone – All functionality is operational as a standalone unit. Time updates available through GPS syncs. Controller can be programmed to use the GPS output for keeping its internal TOD clock accurate. 1 Master Control – In conjunction with a Marc Master Controller, SEPAC will work within a closed loop system. 2 System Control – SEPAC has the ability to communicate to TACTICS® and operate under system control. 3 Manual – SEPAC can be controlled manually to run specific coordination routines when set to manual, including free operation. 4 Adaptive Control – SEPAC can accept commands from SCOOT® for adaptive control, if available. 5

11 Restricted © Siemens Industry, Inc All rights reserved.Answers for industry. Siemens Adaptive Control Effective traffic control solutions

12 Restricted © Siemens Industry, Inc All rights reserved. Page 12Infrastructure and Cities / Mobility and Logistics / Intelligent Traffic Solutions Current Traffic Landscape Annual delay per traveler increasing at a rapid pace Freeway usage is reaching peak capacity and spilling out onto arterials

13 Restricted © Siemens Industry, Inc All rights reserved. Page 13Infrastructure and Cities / Mobility and Logistics / Intelligent Traffic Solutions Congestion Impacts All of Our Lives © Siemens AG billion tons of air pollution 170 billion gallons of excess gas Effects 33% of all accidents

14 Restricted © Siemens Industry, Inc All rights reserved. Page 14Infrastructure and Cities / Mobility and Logistics / Intelligent Traffic Solutions How Does Adaptive Control Work? New timings are developed 4 Special tuning, weighting and logic is factored 3 Information input is placed into algorithms 2 Real time data collected 1

15 Restricted © Siemens Industry, Inc All rights reserved. Page 15Infrastructure and Cities / Mobility and Logistics / Intelligent Traffic Solutions Optimizing Signals Gives Added Benefit in Reducing Stops, Delays and Fuel Usage Achieves significant reductions in vehicle delay (21%), stops (25%), and fuel consumption (5%) 35% reduction in delays on a section of State Highway 6 in Houston, Texas $787,000 in benefits to the public for one year of operation in Bradenton, Florida

16 Restricted © Siemens Industry, Inc All rights reserved. Page 16Infrastructure and Cities / Mobility and Logistics / Intelligent Traffic Solutions Siemens has two proven Adaptive Control systems to fit the unique needs of your city: ACS Lite and SCOOT®

17 Restricted © Siemens Industry, Inc All rights reserved. Page 17Infrastructure and Cities / Mobility and Logistics / Intelligent Traffic Solutions ACS Lite Adaptive Signal Coordination Software

18 Restricted © Siemens Industry, Inc All rights reserved. Page 18Infrastructure and Cities / Mobility and Logistics / Intelligent Traffic Solutions ACS Lite Overview Adapts and optimizes the splits and offsets of signal control patterns/plans along an arterial application Resulting in reduced delay, stops and fuel consumption Has flexibility to be deployed as an on-street master or as a centralized system

19 Restricted © Siemens Industry, Inc All rights reserved. Page 19Infrastructure and Cities / Mobility and Logistics / Intelligent Traffic Solutions Siemens developed ACS Lite under contract to the Federal Highway Administration as a more accessible way to implement adaptive control Low Cost Design – make it easy Leverage existing infrastructure Standard US-style actuated controllers and logic (rings, phases, splits, barriers, gap-out/extension, etc.) Typical agency detector layouts Typical communications Use NTCIP Promote efficiency Goals of ACS Lite

20 Restricted © Siemens Industry, Inc All rights reserved. Page 20Infrastructure and Cities / Mobility and Logistics / Intelligent Traffic Solutions What Parameters Does it Adjust? Controllers use normal timing plans ACS Lite changes splits and offsets based on traffic demands Cycle length is changed by time-of-day (TOD) Actuated logic and sequences are used Still use TOD changes

21 Restricted © Siemens Industry, Inc All rights reserved. Page 21Infrastructure and Cities / Mobility and Logistics / Intelligent Traffic Solutions Findings An ACS Lite system can help to effectively reduce travel time on main street and queue length on side streets during peak periods, which in turn improves system efficiency, reduces emission and fuel consumption. Up to 32% reduction in travel time on newly time signalsAverage of 20% reduction in side street queues
