Urban development along rails in other Asian regions
Published in Junyi Zhang, Cheng-Min Feng, Routledge Handbook of Transport in Asia, 2018
Monorail, as the term suggests, is a rail technology whereby the track consists of a single rail. While monorail is mostly seen as a people mover in airports and amusement parks, there are increasing interests in and applications of monorail systems for urban transit. Monorail transit services are comparable to LRT in terms of capacity and riding performance. In most cases monorail runs on an exclusive right-of-way.

With the development of urban traffic and traffic congestion, more and more cities pay attention to urban rail transit as a means of transportation (Timan 2015). APM, straddle monorail, suspended monorail and subway have become an important part of Urban Rail Transit (Zhang 2016). Megacities have increased traffic demand, driving the transport sector to plan new projects and expand existing monorail systems to meet growing demand (Mabrouk 2015). There are two main types of straddle monorail vehicles: a two-axle bogie and a single-axle bogie. Straddle-type monorail vehicles with Single-axle bogies serve as airports, high-speed rail stations, connecting lines for subway traffic, high-speed rail stations, connecting lines for subway line traffic, urban trunk lines for mountainous cities or for medium and small-sized urban rail transit in second-line cities in big cities (Miller et al. 2014). The introduction of monorail can effectively alleviate the congestion of urban commuter travel environment, save travel time and reduce carbon dioxide emissions (Manoratna, Kawata, and Yoshida 2017). Straddle-type monorail vehicle with Single-axle bogies, as a new rail transit system with good curve passing and tyre wear, are being used in Bombardier, Canada and BYD in China.

The monorail vehicle, as an alternative mode of transportation, has become popular among the world recently owing to its tremendous advantages compared to the conventional rail vehicle, especially in some regions where the conventional railway line cannot be constructed, such as mountain area. The articulated monorail's vehicle models are set up with the main components of the vehicle model of the traditional monorail. Therefore, it is necessary to build the traditional vehicle model first. There are many articles introducing the structure of the vehicle [23–32]. A typical monorail vehicle is supported by two straddle-type bogies through secondary suspension, and the straddle-type bogie operates on the elevated beam-like bridge through the driving wheels, guide wheels and stable wheels. The driving wheel is a kind of solid rubber wheel used to support the weight of vehicle. This also enables to provide much larger traction force and lower noise emission comparing to the conventional wheel/rail contact. Four guide wheels, horizontally installed on four corners of each bogie, interact with both sides of beam so as to yield the lateral guide forces when the vehicle negotiates the curve. The guide wheels located on both sides of bogie frame are used to provide the anti-roll moment.

Monorail systems respect the environment, they have the least negative impacts regarding to environmental measures such as noise and air pollution, traffic congestions and harmful emissions. They are one of the cleanest options for mass public transport, as they run on electricity or battery. (10) Pedestrians: Walking to work, school and to shops does not emit any greenhouse gas. It does not cost any expenses and walking is good for the human health.
