Optimal Design Of Traffic Demand Management Strategy For Shenzhen Municipality

With the rapid development of Shenzhen’s urban construction, society’s economy and population, Shenzhen citizen’s ownership of automobiles is increasing dramatically, so with the urban road’s traffic pressure. Also, automobile’s emission pollution has become the primary source of Shenzhen’s air pollution. As of December 29, 2014, Shenzhen citizens owned3,190,000 vehicles, and the traffic jam and congestion is increasing seriously. Issues so caused by the loss of time for personnel and cargos, environmental pollution and energy consumption are increasingly severe, which has brought certain effect to Shenzhen’s harmonious development of society, economy and environment. Although by taking measures such as greatly developing public traffic, improving urban road network and building smart traffic etc, Shenzhen is striving for enhancing the road network capacity and improving the public traffic sharing rate, while Shenzhen’s future traffic development will face more serious situation under the circumstances that the increase range of traffic need and automobile’s ownership is greatly larger than that of road supply.Shenzhen has implemented some traffic need management measures such as staggered rush hour plan, traffic management of even and odd-numbered license plate for several part of the road sections, and management of automobile’s environmental classification for several regions,which do play an important role for alleviating traffic congestion under the circumstance of highly increasing of automobile’s ownership. For the purpose of alleviating traffic congestion and improving atmosphere environmental qualities, Shenzhen has implemented the car increment regulation and management since December 29, 2014. However due to Shenzhen’s great car inventory, it was still increased at least 3.2% in 2015, while is higher than the road mileage’s annual growth rate of 1.2% in recent years. Also, car’s use intensity of Shenzhen is always staying at a high level, and the private cars’ average daily times of travel are as high as2.35 times, which is almost 3 times of Tokyo and 1.6 times of Hong Kong. Besides, with Shenzhen’s urban high-strength exploitation and the acceleration of special economic zone’s integrated construction, separate working and living regions are further intensified, and the traffic supply and demand contradictions are still outstanding, so strong and powerful traffic need management measures are needed to be facilitated.Traffic need management is an important way of facilitating the balance of traffic demand and supply. Traffic need management measures are helpful to adjust the use of car, guide the rational travel of residents to public traffic so as to propel the conversion of traffic need fromimbalance to balance. Experience of advanced cities indicates that carrying out traffic need management is the only way of mega-city’s traffic development. Large cities in countries and regions like Singapore, Hong Kong SAR, Europe, America, Japan and South Korea etc. has carried out a series of traffic need management measures, which has brought favorable effect to settle the issue of alleviating urban traffic congestion.By analyzing Shenzhen’s urban and traffic development current situation, existed issues and traffic development tendency, as well as referring to the domestic and foreign traffic need management experience, the essay analyses the traffic need management measures which has been already implemented by Shenzhen Municipality, proposes design plans for optimizing traffic need management measures which are suitable with Shenzhen’s traffic development status and traffic policies, which provide technical support for Shenzhen’s stimulating of traffic need management strategy and facilitating traffic need management measures.
