1 Symposium on Public Transportation in Indian Cities with Special focus on Bus Rapid Transit (BRT) System New Delhi Jan 2010 Role of Intelligent Traffic Systems Dr. Thomas Wenzel Siemens Mobility Division

2 Role of Intellligent Traffic Systems 1. Intelligent Traffic Systems 2. Emission saving potential 3. Intermodal interactions 1. traffic information (incl. Park & Ride) 2. Improvement of transshipment at hubs and terminals 3. BRT 4. Congestion charging

3 Management & Information Strategic Management Level Control Centers Enforcement Urban Traffic Control City Global Mobility Tolling Scenarios Se Performance contracts Engineering Freeway Tunnel Parking Maintenance Management Management Guidance Spare Part Logistic On Street Traffic light rv ice DetectionAutomatic Number plate recognition Variable message signs Pay & display machines

4 Siemens has a long and successful history in traffic and transportation technology First traffic signal in Germany Berlin, 1924 Traffic signal Chicago, 1926 Radar detector, Automatic Signal 1), 1966 Plessey microprocessor traffic controller, 1970s Traffic controller, 1937 Traffic Eye Universal, 1998 Traffic management center Berlin, 1961 Traffic Management Berlin 2003

5 The benefits of implementing ELV traffic Increased electrical safety For members of the public in the event of damage to the signal installation For personnel working on or around the intersection Also has the potential to reduce the use of ladders Pole terminations are possible at the pole base with no associated electric shock risk

6 Real benefits for a junction PE T NR Annual power (KWH) Annual CO2 (Metric Tons) 0 Meters Reduces power consumption and CO2 emissions by 70% compared with standard HI signals Estimated life costs ( K) HI CLS LED ELV LED Yr Yr Yr Yr Yr Yr Assumes bulk lamp change is eliminated and routine cleaning reduced to once a year

7 The benefits of implementing ELV traffic Reduced energy consumption Latest generation Helios ELV signals are very low power Offer up to 80% power saving over traditional signals Potential for considerable energy cost savings and reduction in carbon footprint

8 Intellligent Traffic Systems improves traffic flow and reduces harmful emissions Performance indicators (waiting times): % -26% Background: Nationwide representative study on the MOTION method 24 intersections along the busy 6-km-long street Three methods examined: Fixed-time control Conventional method Adaptive control (MOTION) -38% -37% rush hour 07:00 09:00 rush hour 16:00 18:00 MOTION Conventional Fixed-time

10 Example for direct intermodal actions: Intermodal traffic information and management (incl. Park & Ride) Intelligent Intermodal Traffic Information: Better usage of existing transport capacity Ecological advantages (less particulates, less noise etc.) Service improvement for Users City attractiveness Traffic Management System Traffic Detection Units Loops Infrared Public Transport Information System Traffic Data Collection + Public Traffic Situation Transport Data Parking Data + Parking Systems Occupancy data GIS Visualisation Strategy Management... AND accident ahead Sub category = right lane closed Service provider... Navigation system 1. Set Dynamic Message Signs 2. Inform Media 3. Send TMC messages Radio On-street Trigge r Main category = ACCIDENT take next exit U to city every 5 min Back-Office Operator

11 Example for direct intermodal actions: Improvement of transshipment at hubs and terminals The efficiency of inter-modal freight transport will be considerably improved by speeding up operations of transshipment centers

12 Bus Rapid Transit BRT Bus Priority System Public Transport Information System BRT Stop Equipment Instant mass transit facility operating like a little metro system Low investment Upgradable to LRT System possible at any time Flexibly adaptable to capacity needs Reduced pollutions due to management of cruising speed Higher transport capacity than a regular bus system can do Good acceptance by the public Onboard Equipment AVL On-street Operation Control Management System Data Collection + Public Transport Data Time Schedule Data GIS Visualisation BRT Management Schedule Management Shift Management Bus Maintenance Emergency / Security Ticket Vending Asset Management Back-Office Operator

13 Two different Bus Priority alternatives In Combination with an ITCS Based on On-Board-Unit with ITCS Functions Use of special functions of the ITCS (e.g. localization) Use of analogue short range radio (SRR) or radio broadcast (digital) Advantage: system provides priority according to schedule (ahead or after) and planned driving direction at the intersection As Stand-Alone-System Based on On-Board-Unit with reduced functionality (location, communication) Use of GPRS or SRR Communication Advantage: lower investment costs

14 Example: Signal switching for route # 54 Sign On 1 Sign On 2 Sign Off - Route Trip 54 - Stadium - Deviation - yes - - Route Trip 54 - Stadium - Deviation - yes Route Trip 54 - Stadium - Deviation - yes -. Distance 1 Distance 2

15 Bus Priority Results : Example Darmstadt (Germany) Route Travel time previous Travel time now Travel time saving 33 minutes 22 minutes 11 minutes 25 minutes 17 minutes 8 minutes Eberstadt / Wartehalle Merck 28 minutes 17 minutes 11 minutes Eberstadt / Wartehalle Luisenplatz 20 minutes 12 minutes 8 minutes Eberstadt / Frankenstein Merck Eberstadt / Frankenstein Luisenplatz

16 80 % of our customers in the EU ordered a UTCS together with an ITCS Basel (CH), 1999 ITCS Bern (CH), 2000 Bremen, 1996 u Erfurt, 1995 u Freiburg (D), 2001 Hamburg (D) Innsbruck (A), 1996, 2002 Leipzig (D), 1997 Luzern (CH) München (D), Würzburg (D), Krakau (Pol), 2009 Halle (D), 2009 Erlangen (D), 2009 Nürnberg (D), 2009

17 Congestion Charging Why? Introduced February 2003 Contributes directly to four of the Mayor s transport polices: Reduce Congestion Improve Bus Services Improve journey time reliability for car users Make distribution of goods and services more efficient
