1 Access Line Operation Analysis & Case Study in Beijing Metro System Zhili Liu, Ph.D. School of Traffic and Transportation Beijing Jiaotong University
THE DEVELOPMENT OF BEIJING METRO NETWORK OVERVIEW CALIFORNIA 2 GATEWAY CITIES PORT OF LONG BEACH PORT OF LOS ANGELES An Overview of Beijing Metro: 15 Lines, 192 stations and 372 km (231 mi) of track ; 4 th in track length, after Shanghai, London and Seoul. 2 operators: Beijing Mass Transit Railway Operation Corp. (state owned), Beijing MTR Corp. (public- private joint-venture with the Hong Kong MTR). 2.18 billion riders (2011), 4 th in annual ridership after Tokyo, Seoul and Moscow. A single-day record of 8.4 million (on April 28, 2012). A flat fare of RMB(¥) 2.00 was introduced on October 7, 2007 before 2008 Beijing Summer Olympics except Airport Express ¥25.00.

7 Nearly 100% transfer to Line1 during AM rush hours
Upgrade signal system to reduce headways (76.4%) Enlarge fleet size 4 cars to 6 cars (164%) Control traffic on platforms Control traffic outside stations Open a BRT on Jingtong Expressway 8 ENHANCING THE CAPACITY IN BATONG LINE MEET THE CHALLENGE
9 ENHANCING THE CAPACITY IN BATONG LINE MEET THE CHALLENGE
JINGTONG BRT OPERATION 28 bus routes run on the BRT lanes, 10 on inside BRT lanes and 18 on outside BRT lanes. Buses run on the BRT lanes at the speed of 50 km/h, an increase of 108% of speed since BRT lanes were operated. Over 120,000 people take buses during AM and PM peak hours. Passenger volume going the downtown area by bus increases 8,000 during AM peak hours. Private vehicle keeps speed unchanged during AM peak hours, but in the PM peak hours the speed of private vehicles reduces 30%.
BATONG Line OPERATION After Before Passenger volume on the Batong line reduces more than 6,000 passengers /day during the AM peak hour of the first 3 days. Passenger volume was reduced in the stations close to the departure stops of BRT.
JINGTONG BRT OPERATION MODE SHIFT 64% from existing bus services 15% from Metro 10% from bus+Metro 6% from private vehicles Bus Metro Bus+Metro Car Taxi Others
The study has showed that the Batong line has experienced heavy congestion in the AM and PM peak hours. A number of solutions has been implemented to reduce the congestion on the Batong line. The BRT lines has attracted the traffic from the Metro system. Further research is needed to study the impacts of BRT services on the Metro system. CONCLUSIONS 15
