many buses to send at any time, to avoid the
disadvantages of not having enough buses during
rush hours and too many buses during rush hours (Gu,
2014). Finally, according to the Doppler effect, the
speed limit and position of the driver are judged. It is
a phenomenon that when the wave source and the
observer have relative motion, the frequency of the
wave received by the observer is not the same as that
sent by the wave source. Drivers' operating
companies will monitor activities with a mobile
speedometer to ensure that drivers drive according to
regulations. Traffic police emit ultrasonic waves with
known frequencies to move vehicles and measure
reflected waves' frequency. The speed of vehicles can
be known according to how much the frequency of
reflected waves changes. A monitor equipped with a
Doppler speedometer sometimes mounted above the
road, takes a picture of the vehicle's license plate
number while measuring the speed and automatically
prints the measured speed onto the picture (Chan,
1970).
7 THE IMPORTANCE OF
PUBLIC TRANSPORTATION
SYSTEM IN CHINA
As China develops and progresses, the transport
needs of its citizens and the lagging development of
its public transport system have led to severe
challenges for the country's public transport system.
Due to factors such as road conditions and the number
of vehicles, the government's investment in
conventional public transport is yielding less and
fewer results, while large scale rail transport, such as
the metro, is a substantial investment, has a long
construction cycle and has demands on the city.
Therefore, high-capacity, universal public transport
systems with low investment, short construction
cycles and ease of management mean that public
transport systems have relevance and a need for
improvement in China (Liu and Ceder, 2015).
8 THE ENLIGHTENMENT OF
BRITISH PUBLIC TRANSPORT
SERVICE TO CHINA
A combined public-private model can better facilitate
development. In China's socialist market economy,
the Chinese government focuses on protecting
national industries and the interests of the people.
However, the government's introduction of private
enterprises in urban public transport can improve the
efficiency of the entire transport system, making the
existing public transport model better and ultimately
creating a virtuous cycle of public transport trends. In
regions where private enterprises are relatively
developed, some private enterprises can be
introduced to operate public transport institutions to
reduce the government's financial burden and inject
confidence into the public transport service industry
(Wang et al., 2018). Of course, private enterprises
should be monitored by regulatory bodies to prevent
the interests of the public from being compromised.
For example, the government should ensure the
effective use of existing buses, facilities and staff
skills to ensure the continuity of passenger services.
Generally speaking, private bus companies have
limited capital and weak technical skills to undertake
large-scale passenger transport tasks or build
extensive transport facilities. Secondly, state-owned
bus companies should operate the most efficient peak
hour bus routes in densely populated urban areas.
Private bus companies should be considered for less
dense and less efficient suburban bus routes during
off-peak hours for contracting to take full advantage
of their low costs and operational flexibility. Such a
strategy may be in the best interests of the public and
private sectors and passengers (Gormley et al., 1989).
To ensure the quality of public services, the
government has also established a mandatory exit
mechanism for private bus companies. If their service
quality is poor, accidents are frequent, and passengers
complain, the government should punish them by
eliminating substandard operators and replacing them
with new ones to ensure good service (Gormley et al.,
1989).
9 CONCLUSION
In conclusion, by exploring the public transport
system in the UK, this paper argues that under the
conditions of China's socialist market economy, the
privatisation of urban public transport can, to a
certain extent, compensate for the shortcomings of
traditional public transport. Therefore, the
government's introduction of advanced information
technology can improve the quality of public
transport services, thereby increasing the efficiency
of public transport and reducing operating costs.
