    Development of a personal vehicle type choice model for Sri Lanka
    (Department of Civil Engineering, University of Moratuwa, 2018-09) Perera, KR; De Silva, D; Pasindu, HR
    Vehicle ownership is a key determination factor in any country’s economy. In the Sri Lankan context, it has been identified that vehicle ownership rate has expressively increased over the last decade. Apparently, the road congestion in urban and suburban areas also have increased significantly. As controlling measures of reducing new vehicle imports, and promoting environmental friendly vehicles, the government has introduced new taxes as well as some increments in the tax level on private passenger vehicles. The overarching object of the research was to examine how a new vehicle choice may vary in the context of household socio – economic characteristics ( eg. income level, number of households, age of the user, gender of the user etc), and the regime of new pricing reforms for annual and variable charging on the vehicle price itself (eg. fuel, insurance and other operational aspects and change of user requirements such as enhancing the vehicle seating capacity, shifting vehicle operating method etc). The respondents participating in the survey, ‘household choice of a new personal vehicle, must have purchased a new vehicle, as the survey is designed accordingly. This paper examines the development of a type of vehicle ownership model using a sample of people living in the Western Province of Sri Lanka. A sample survey is being conducted in the Western Region to collect household data in 2013. ALOGIT software is used to obtain the results of this research. This research considers several potential determinants of vehicle choice, including socio-demographic status. This study primarily attempts to identify how to recognize the family's monthly income, age, occupation, social status, and number of drivers in the family, and their influence on the ownership of the car. The main objective of this research is to help planners and traffic designers to solve the planning and traffic problems in the Western Region. In addition, the result of this research is to assist the Sri Lankan government in imposing the required taxes, and providing as much funding as possible to maximize a sustainable and environmentally friendly transportation system in Sri Lanka.

    Study of mode selection behaviour of passengers across the Western and Southern Provinces at coastal transport corridor
    (Sri Lanka Society of Transport and Logistics, 2019-09) Liyanage, TU; Samarakoon, GS; Perera, KR; Gunaruwan, TL
    The Coastal Transport Corridor consists of the Coastal Railway Line, Colombo - Galle (A002) Highway, and the Southern Expressway (E01). Between 2013 and 2017 both the Southern Expressway and the Coastal Railway Line were extended up to Matara in order to increase their reach. This research paper attempts to investigate how mode choices of passengers have switched between the Coastal Railway, Galle Road (A002), and Southern Expressway (E01) in the years since 2013 – 2017 by analysing modal splits in 2013 and 2017. The modal splits are determined using empirical data collected from classified vehicle counts, railway passenger counts, and bus volume counts carried out on the Western and Southern Province border for all three routes in 2013 and 2017. The research also attempts to analyse possible reasons for any shifts in modes between the three transport routes. A significant reduction in passenger volumes has been observed over time in rail transport towards Western Province during the morning peak. The number of luxury buses on Galle Road (A002) has reduced, together with the demand for the passenger volumes. However, the bus service on E01 has managed to entice rail and bus passengers away from A002. This suggests that, despite all three routes having the same reach, buses on E01 have managed to capture more commuters travelling from Southern Province to Western Province. A noticeable modal shift has taken place between modes of public transportation (rail and bus) rather than the desired shift from private to public transportation. This shift has also been facilitated by the increasing interconnectivity of Expressways in Sri Lanka (E01 and E02), resulting in a wide range of bus routes originating from Kadawatha, Colombo Fort, Kaduwela, etc. to transport passengers between the Western and Southern provinces. While a majority of passengers use public modes, the popular mode of choice among private modes is car. However, out of all the vehicles that used E01, cars made up 56.81% in 2017. Compared to the percentage of cars in E01 in 2013, this is an increase of 7.39% in just four years. In order to avoid car demand exceeding the capacity of the E01, solutions that entice car users to choose public transportation are recommended. Therefore, more investment is required to promote buses on E01 as an alternative mode of transport that can provide the comfort, reliability, and other attributes of travelling by car. Furthermore, Sri Lanka Railways needs to pay attention to different market segments and fulfil needs of passengers belonging to each sector, in order to entice a modal shift.
