The City
Shanghai, the largest city of China, is often regarded as the country’s centre of finance and trade. Modern development began with the economic reforms in 1992. Since then Shanghai has quickly overtaken other cities and maintained its role as the business centre in China. It also hosts the main stock market in China. Since 2005, Shanghai has ranked first of the world’s business cargo ports. Meanwhile Shanghai is becoming a transport hub with a network of highways, railways and two international airports in connection with other cities located in the Yangtze River Delta Region. With the extension of urban area, Shanghai has constructed a rapid road network comprising 3 elevated rings and several arterials which is still under completion. In addition to a large bus fleet of over 1000 bus routes (urban and suburb), Shanghai has been developing a metro system since 1995 which has become one of the newest and fastest-growing rapid transit systems in the world. Today, there are 13 metro lines (including the Shanghai Maglev Train), 268 stations and 420 km of tracks in operation. By 2020, it will have reached 18 lines with 524 stations in total. The metro transports 4.78 million passengers per day, accounting for 35% of total passengers taken by public transport.
Viajeo in Shanghai
The open platform in Shanghai will integrate data from different data sources, such as floating vehicles and existing traffic data to deliver real-time estimation and short-term forecast of traffic conditions. The real-time estimation and short-term forecast of traffic conditions will be used to forecast real-time bus arrival times to be displayed at bus stops. On the demonstration bus line (No.146), at least 5 bus stops will be used to display bus real-time information. The LED screen displays at the bus stops focus on predicated bus arrival time by showing the distance information of “Next bus of 164 is X stops far from here”. At the same time, the predicated arrival information both by distance and by minutes will be released on the WEB terminals. A special focus is given hereby to public transport standards (TRANSMODEL, SIRI, IFOPT). Standard protocol related messages are used to realise defined scenarios for Public Transport information transmission and transport infrastructure specification. For example some functional services of SIRI will be adopted, including vehicle monitoring and location (VM) service.
Another special focus of the demonstration in Shanghai is to correlate traffic data with environmental data in order to develop a substantial understanding of the environmental impacts of road transport. Within the project, the connection of traffic data to emissions is assessed. The European Handbook of Emission Factors (HBEFA) is transferred to the Shanghai situation. This is used to develop and validate a traffic model which can assess environmental impacts of road traffic. The traffic model will be used for appraisal of transport policy and planning. It is set to be a basis for both off-line planning and on-line impact assessment of traffic related emissions.
The pollution calculation will be used to identify “hot spots” of air pollution in Shanghai allowing mitigation plans, such as introducing new public transport services and improving of interchange. The data will be also used to develop bus timetables for transport operators. The display status will also be shown on the internet.
