The transport infrastructure in the Kingdom of Cambodia is in a serious state of disrepair. In particular, the Phnom Penh metropolitan area, as the capital city of the kingdom, is experiencing serious transport problems caused by inadequate transport facilities and management system set against the rapid growth of population and socio-economic activities. This growth is causing a sprawling phenomenon especially in the newly developing zones surrounding the built-up area. This paper examines the core problem and its measure.
Recently, the population of Phnom Penh has reached over one million[i] (1.4 times increase in 1991-2000 period) under stable domestic conditions after the end of the civil war in 1992. The urbanized area of the capital city, which is approximately 27 km², has rapidly expanded to the surrounding suburban areas of about 412 km². Additionally, motor vehicles show a remarkable increase (2.6 times increase in 1991-2000 period) in terms of the number of registered vehicles with a total of approximately 295,000 motorized vehicles, of which about 247,000 are motorcycles and 48,000 are passenger cars. In addition, linked with international routes No. 1 and No. 5 of the Asian Highway Network, Phnom Penh has historically been the core city of land transportation in the area. At present, the poor and deteriorated road network is causing an increase of traffic concentration in the urbanized areas of the city. Moreover, the traffic flows concentrate into the built-up area and traffic congestion occurs on the arterial roads during morning and evening peak hours. The existing traffic management facilities such as traffic signals, signs and pavement markings are not sufficient.
These poor management conditions coupled with shortage of traffic safety facilities and traffic safety education contribute to an increase in traffic accidents. In addition, most of the public transport is served by motorcycle-taxi (motodop), due to the lack of a mass public transport system. Traffic congestion and poor pavement condition are also imposing environmental pollution with increased emission of noxious gases from the vehicles and dust from unpaved road surface. It can be stated that the transportation system of the Phnom Penh Metropolitan Area is lacking proper planning as well as facilities and it depends comprehensively on motorcycles as the most predominant mode for transportation.
With the rapid growth in population, urbanization and motorization in the city, the problem of traffic congestion has imposed itself to be a major issue for concerned authorities. These authorities decided that in order to solve the transport problems, a comprehensive master plan covering the areas of road network improvement, public transport and traffic management should be developed with a time horizon of 2015. The plan aims at providing transport facilities and measures to solve various problems of transport and to support increasing socioeconomic activities and sustainable urban development. The formulation follows the step-by-step process.
Firstly; present and future transport issues are identified and evaluated, which provide the fundamental engineering base of the Plan. Simultaneously, the present socioeconomic profile and future development are estimated based on existing and future land use and MPP development policy. Secondly; the transport planning policy is established to directly response the transport issues and future traffic demand as well as future land use and socioeconomic development. Based on this policy, transport system alternatives are generated and evaluated. The optimum alternative is selected and evaluated in view of network efficiency, benefit, effects as well as environmental assessment. Thirdly; the Transport Sector Plan is formulated, namely road, public transport and traffic management. 4th Step; the overall implementation plan of the Plan is proposed with due consideration of institutional organization, human resource capability and financial restriction. Finally, the overall implementation plan of the Plan is proposed with due consideration of institutional organization, human resource capability and financial restriction.
In conclusion, in order to improve transport system in Cambodia, there are four steps to implement: (1) identification of current situation, (2) evaluation of existing transport planning policy, (3) improvement of road, public transport and traffic management, and (4) building human and financial resource for implementation of master plan.
