Accessibility issues to public transport in Sri Lanka
(Sri Lanka Society of Transport and Logistics, 2023-08-26) Malagalage, M; Amarasingha, N; Gunaruwan, TL
Most of the time people need to travel some distance to access public transport services as they do not provide door-to-door services. Walking is the most common and affordable method to access public transport. Good accessibility may attract more people to public transport. This research finds out the accessibility issues faced by people when they are reaching public transport in Sri Lanka. To find out those accessibility issues, a questionnaire survey is conducted focusing on public transport users. The survey mainly focuses on personal, trip, and access characteristics. In order to identify the existing accessibility issues, the data are analyzed using statistical methods, and significant differences are identified using Chi-square tests. Understanding the accessibility issues to public transport helps to enhance the current state of public transportation in Sri Lanka. The result of this analysis provides valuable insights into the issues faced by travelers while accessing public transport in day-to-day life. Understanding the accessibility issues to public transport will help to provide significant perception into the existing condition of accessibility in Sri Lanka and inform policymakers about the steps which need to be taken for further development.

(Sri Lanka Society of Transport and Logistics, 2024) Samarasinghe, N; Amarasingha, N; Withana, S; Gunaruwan, T. L.
Traffic congestion emerges as a significant concern, further amplified by the increasing population and urbanization rates. The rise in vehicular and pedestrian traffic contributes significantly to traffic congestion, exacerbating issues related to mobility, sustainability, and environmental health. Implementing effective traffic management strategies is critical for mitigating these challenges. The objective of this study is to enhance the performance of existing Traffic Control Systems and to analyze the coordination of junctions using micro stimulation software. Using this microsimulation software, it is possible to analyze traffic video footage from the junction under study and extract important traffic flow data for analysis. Despite the availability of numerous studies, a significant gap remains in effectively using simulation models to address congestion issues in Sri Lanka. This study seeks to close this gap by investigating the most effective use of microsimulation software for traffic management in Sri Lanka.

Assessing the feasibility of using hospital data for accident analyses
(Sri Lanka Society of Transport and Logistics, 2023-08-26) Vidanagamage, RS; Gunathilaka, S; Amarasingha, N; Gunaruwan, TL
Road accidents are a significant public health concern in Sri Lanka. Accident data are usually collected from police inventories. However, hospital data can provide detailed information on the severity of injuries, the circumstances of accidents, and the demographic characteristics of the victims compared to police reports. This helps us understand accident patterns better and how they affect public health. With this comprehensive view, we can find under-reported accidents, accident hotspots, and specific risk factors. This helps policymakers to create targeted strategies to prevent accidents. Healthcare professionals can also use this data to improve medical care for accident victims, which may reduce the number of deaths and injuries. Overall, using hospital data helps us make better decisions, leading to safer roads and healthier communities. The objective of this research is to determine whether hospital data can be a valuable source for accident analysis and identify necessary steps for its effective use. Both police and hospital accident records are collected during the data collection including accident severity, socio-demographic information of the victims, and other important factors for accident analyses. The study evaluates the quality and reliability of hospital data and asses its potential for improving the scope of the accident analysis incorporating more factors such as injury types, deaths before and after a certain age, length of hospital stay, long-term disabilities, etc. The methodology includes a review of the relevant literature and an analysis of accidents from a sufficient sample of police and hospital data. The findings of this study provide important insights into the potential use of hospital data for accident studies, as well as improve the accuracy and efficiency of accident investigations.

Effect of traffic entries and exits at the major road on its performance
(Sri Lanka Society of Transport and Logistics, 2023-08-26) Suraweera, NT; Amarasingha, N; Gunaruwan, TL
The transportation infrastructure is one of the crucial factors that affects economic growth and social development in the world. Roadside friction can be defined as the activities taking place by the sides of the road that restricts a smooth traffic flow on the road. Roadside frictions are increasing proportionally to the increase in population and urbanization. Roadside friction directly contributes to traffic congestion and road accidents. Entries to- and exits from- major roads can be identified as one of the major types of roadside friction in developing countries like Sri Lanka. As the approach methodology of the study, videography techniques were carried out to collect traffic data. The analysis was conducted using PTV VISSIM microsimulation software to determine the increment of the travel time due to roadside friction of traffic entries and exits from the major roads. Travel time comparisons were made with the presence and absence of roadside friction. The results indicated that travel time increments for the combined friction of entries and exits from the major road and on-street parking conditions vary from 25 to 90% when compared to the frictionless condition depending on traffic flow.

The impact of road surface distress on capacity
(Sri Lanka Society of Transport and Logistics, 2023-08-26) Nandasiri, N; Amarasingha, N; Gunaruwan, TL
This research aims to investigate the impact of road surface distress on the capacity of the road. Road capacity is a critical factor in the efficient and safe movement of traffic. Road surface distress such as potholes, cracks, and rutting can significantly affect road capacity and lead to reduced traffic flow, increased travel time, and higher vehicle operating costs. To achieve the research objective, data on road surface distress and traffic flow are collected from a range of different road types and locations. The collected data are analysed using statistical methods to identify correlations between road surface distress and traffic flow. The results of this research provide insights into the relationship between road surface distress and road capacity, which can be used to improve road maintenance and design practices. By understanding the impact of road surface distress on capacity, transportation agencies can prioritize maintenance and repair activities to maximize the capacity of the road network and reduce the negative impact of road surface distress on road users.

Pavement roughness monitoring using android-based smartphone application in low-speed roads
(Sri Lanka Society of Transport and Logistics, 2023-08-26) Gunasinghe, A; Amarasingha, N; Gunaruwan, TL
Pavement roughness is the imperfections in a pavement surface that affect the ride quality, safety, and some other factors in a vehicle. The International Roughness Index (IRI), a criterion to assess ride quality and pavement unevenness, can be used to express roughness. There are several ways to obtain data regarding the condition of the road surface, but almost all of them run at low speeds with significant reliance on human involvement or call for advanced measurement tools, which typically have high costs and demand expert operators. A major percentage of the road network is not covered by the annual collection of pavement condition data by several transportation organizations. The data collection was done in the Roadroid application by selecting video mode in Roadroid application. Finally, IRI values obtained by RDA were compared with IRI values generated by the Roadroid application. Based on the relationship between the RoadRoid and actual IRI values of Sri Lanka’s Road Development Authority (RDA), statistical analysis shows a linear regression model with R2 = 0.766. The experiment's results support the smartphone app as a practical substitute for evaluating pavement roughness on low-speed roads, offering efficient data delivery and technical benefits.

Road safety evaluation in Galle: towards star rating for Sri Lankan roads
(Sri Lanka Society of Transport and Logistics, 2023-08-26) Tharaka, H; Amarasingha, N; Gunaruwan, TL
With the increase in transportation facilities, Sri Lanka has a high demand for the transportation sector. However, the existing road classification in Sri Lanka is challenging for people to judge their efficiency and safety. The standard of road classification needs to be self-explanatory with its infrastructure standard and road safety, in Sri Lanka that can be accomplished by performing a road safety evaluation. This study contributes to the improvements of the prevailing safety assessments regarding roads in Sri Lanka to the required standard. This can be performed through a road star rating system for Sri Lankan roads which may be based on the International Road Assessment Program (iRAP). The road star rating analysis would assist in locating high-risk areas on the Sri Lankan Road network and prioritizing safety measures to enhance the performance of the roads in terms of safety. The methodology entails gathering and evaluating data on the road network for the purpose of assessing the safety performance of roads using a star rating system. The data collection was done through the Google Earth Pro software, for 30 selected road segments in the Galle district. The analysis of the results will provide insight to identify the relationship that exists between the number of road accidents and the other roadside variables.

Self-reported habitual practices and perceptions of young drivers in Sri Lanka
(Sri Lanka Society of Transport and Logistics, 2020-11) Amarasingha, N; Firdhaws, HMM; Gunaruwan, TL
It is important to identify the young and inexperienced people’s driving practices and perceptions at a very early phase of their driving exposure so that areas of improvement for safer driving can be identified. This study analyses 400 young and inexperienced drivers’ self-reported habitual practices and opinions through a questionnaire survey. This questionnaire focuses on supervision of early driving, restrictions by parents, accident and traffic offences involving young drivers, and several other habitual driving practices. Analyses are performed using reliability statistics, inter-item correlation, likelihood ratio tests, and parameter estimates. The highest inter-item correlation value obtained is 0.467 which was for overtaking vehicles in restricted areas and speeding short distances to run a yellow light before it changes to red. Driving after alcohol consumption, mobile phone usage, taking an illegal U-turn at restricted areas, indicating signals when changing lanes and overtaking a slow driver from the left were significantly influenced by the choice of young drivers to not use seat belts. These habitual practices while driving highlight the need for early intervention to improve road safety. In conclusion, there is always one or more habitual driving practices that affects other driving habits of young drivers.

A study on railway-roadway level crossing safety
(Sri Lanka Society of Transport and Logistics, 2021-10) Ragulan, K; Amarasingha, N; Gunaruwan, TL
The railway-roadway Level Crossing (LC) safety was studied as a significant number of rail crashes are being reported at LCs in Sri Lanka. Four years of railway crash data, LCs characteristics, rail line characteristics, and highway characteristics were collected at railways from Colombo to Polgahawela. It has succeeded in identifying the LCs which had shortcomings such as no barriers, prolonged bell sound, employment of elderly workers in unprotected LCs without basic facilities or assured wages, and view of approaching train being blocked by high rise buildings and trees. Multiple linear regression analyses were done by considering two independent variables at a time. Possible solutions were recommended taking into consideration of the modern methods used in this field.

Vehicle Kilometres Travelled estimates using household travel survey
(Sri Lanka Society of Transport and Logistics, 2020-11) Gunathilaka, S; Amarasingha, N; Gunaruwan, TL
Vehicle Kilometres Travelled (VKT) is a key factor in transport planning and managing, since data represent existing road transport demand or pattern in a specific area of concern. In Sri Lanka, the expansion and development of the transport sector should be complemented with timely updated data in order to fulfil current needs as well as future growth scenarios as a developing country. VKT is a valuable indicator in identifying these requirements; however, timely VKT data for the country is not available within transport communities so far. Very few researchers have attempted to estimate timely VKT over the past few years, and this too in few areas of Sri Lanka. This study aimed to estimate VKT in Southern, Northern, and Eastern areas of Sri Lanka using a questionnaire based - household travel survey. Three areas were visited and randomly selected respondents were interviewed on their travel information on weekdays, weekends, special seasons, holidays etc. Other than number of kilometres travelled, travel mode and socio demographic information of respondents, all of which are useful in estimating Personal Kilometres Travelled (PKT)— were collected. Estimating PKT of individuals seems important in Sri Lanka since a majority of people do not own personal vehicles for travelling. PKT always refers to an individual while VKT refers to a vehicle. The travel distances of samples were aggregated to the annual level and weighted based on census and population data in the corresponding area of study in order to estimate VKT/PKT per person per year. Estimated VKT and PKT for the three areas were statistically compared based on selected socio demographic factors. The estimated VKT would be useful in the transport sector as well as in environmental agencies’ computation of emissions and energy consumption in the country.
