The tram has a history of 100 years and is the one kind transport in Hong Kong that is most environment-friendly. However, it is regarded as outdated and unable to cope with the development of the city. In most cases, it is blamed for slowing down the traffic. The tram runs on rail, so the entire system could be paralysed if any of the tram failed. It is noisy, too. The horrible squeaking noise from the wheels and the rail affects those who live near the track worst at midnight. Here come the solutions. We may either shift to trackless tram, or we may replace the metal wheels with other materials as long as the technical issues about power conduction is fully addressed.
Bus service in Hong Kong is convenient and readily available under the keen competiton in the market dominated by several major suppliers. But the abundant supply of bus service is also blamed for causing traffic congestion, another example that you cannot make the best of both worlds. One of the solutions to the problem is to adopt the "transit-hub scheme", under which transit stations are to be set up for bus passengers. While passengers are encouraged to change bus to travel to different districts, the number of vehicles can be reduced, though this would involve changes in the habit of transport for passengers.
As for the issue of pollution, the bus companys' initiative to shift to new vehicle models such as EuroII, EuroIII and EuroIV failed to produce the desire result to clean the air because the vehicle engines quickly depreciate and emit large amount of exhaust gas when operating on roads that are overloaded and thus badly congested. To solve this problem, we may consider introducing vehicles driven by sustainable power, like ethanol that is widely used in Brazil, or electric-driven vehicles like battery-powered cars.

Tramcar:although it is this harbor is only most vehicle of environmental protection, also have over 100 years of history, the tramcar fall behind, mainly BE jam the road to face;secondly BE it needs the railway track, once having the damage, the whole routes all immediately paralyze!In addition, its high sound is also each kind of transportation most, if you live the wayside building in tramcar, the night is deep a the sound that you necessarily has the feeling-car wheel and railway track to rub, far near all smell.Solve the method a:change to use the trolley bus;solution two:change the nonmetal car wheel.(but must solve to give or get an electric shock the circuit) Bus:although the bus is under a few company competitions currently, supply ample, cause the road face of push to fill, so-called"become also The way that wants to solve as quickly as possible uses"turn the plan in the pivot", establishing the bus to transfer to take the station, the bus exploitation of different region is transfer to take to reduce the amount of car and don'ts influence to order to order of transportation need.(the person in Hong Kong has to adapt this change)Secondly still have the air pollution problem, although currently a few bus companieses all adopt the newer EU two even three and four"environmental protection" vehicles of EU, because the narrow car of the road is many, pushing to fill the severity, the vehicle exhausts to make the waste gas exhausted the increment, can not develop the function of"environmental protection".The solution is the vehicle(as Brazil already a great deal of adoption ethanol is fueling of vehicle) or the electric power vehicle(the electric cell car) that leads into the renewable energy.
