• Developing a mode choice model using stated preference data for Sri Lanka 

  Silva, A; De Silva, D [Conference-Abstract]

  Developing travel behaviour models are important for forecasting travel demand and, consequently, for planning transportation systems. In Sri Lanka, few studies have been done on analyzing mode choice behaviour of individuals. ...
• Establishment of PCU values for urban intersections using drones 

  Senanayake, P; Perera, L [Conference-Abstract]

  Passenger Car Unit (PCU) is used to convert heterogeneous traffic conditions into a uniform traffic flow rate when designing roads and intersections. The impact generated by mixed traffic condition, especially in developing ...
• Development of a guideline to determine structural capacity of demolition waste as a road construction material 

  Jayasooriya, W; Mampearachchi, W; Jayantha, N [Conference-Abstract]

  The use of demolition waste as pavement base material is a promising but unproven technique for road rehabilitation and construction. The scarcity of natural resources for construction industry-related activities was ...
• Application of data science technologies to take proactive decisions to control road crashes 

  De Silva, I; Perera, L [Conference-Abstract]

  Traditionally, road traffic crash analysis and accident modeling resorted to regression models and discrete choice models. Many countermeasures have been identified and implemented but still, the number of crashes and ...
• Evaluation of commercial land price change in response to transport infrastructure improvement: a case study on proposed LRT line in Sri Lanka 

  Iqbal, S; De Silva, D [Conference-Abstract]

  Transportation and Land Use are part of a wider activity system where the interaction between them is part of a complex framework. While the changes in Land Use characteristics would lead to change in activity patterns ...
• An experimental study to evaluate the effective specific gravity estimation on percent air voids of asphalt mixture design 

  Chamodya, H; Mampearachchi, W [Conference-Abstract]

  Asphalt concrete is one of the most widely used surfacing compounds consisting of mineral aggregates with asphalt (Bitumen) binder. Various types of bituminous mixtures such as cold mix asphalt, hot mix asphalt, plant ...
• Barriers in adoption and operation of electric buses into the existing public transit network 

  Thilakshan, T; Sugathapala, T; Bandara, S [Conference-Abstract]

  Transportation has been identified as a major contributor in terms of increase in air pollution and related impacts resulting in climate change and global warming amongst other threats to the world and people. The nature ...
• Enhancing road safety with cost-effective wireless technologies 

  Samarasinghe, T; Sandaruwan, R; Hemachandra, K; Alagiyawanna, I; Sandeepa, S; Dias, S; Wickramarachchi, T; Dharmaraj, N; Dias, D [Conference-Abstract]

  Intelligent Transport System (ITS) applications are imperative for improving safety and efficiency on the road; for instance, accidents at railway and pedestrian crossings with fatal outcomes are frequently reported. ...
• Decision-making framework for effective trip planning based on travel time reliability 

  Vidanapathirana, C; Bandara, S [Conference-Abstract]

  Decision making is a key element in trip planning. As the vehicle volumes on road networks increases, the uncertainty of traffic and roadside situations grows resulting in unreliable travel times. Hence, planning a trip ...
• Applicability of standard density in QC and QA of asphalt surfacing 

  Rathnasiri, P; Mampearachchi, WK [Conference-Abstract]

  The significance of quality control and quality assurance at the compaction operation in the asphalt pavement has long been recognized by the industry since the compaction maintains the volume of air in the asphalt, which ...
• Development of decision framework for dynamic signal timing design 

  Withana, S; Perera, L; Bandara, S [Conference-Abstract]

  The traditional fixed time traffic signal systems use a static signal timing or in other words, a pre designed signal timing developed based on past traffic data. The signal timing design assumes the traffic levels to be ...
• Study on peak-hour traffic reduction and its influence on the Pasyala Junction 

  Wijesinghe, I; Muthuhewa, O [Conference-Abstract]

  When traffic demand meets or surpasses the highway system's available capacity, there are more vehicles on the road than there is sufficient space on the road. The volume of traffic varies according to the time of year, ...
• Corridor level traffic management through variable messaging systems: a case study on east west links entering Colombo 

  Arunakirinathan, V; Premasiri, M; De Silva, D; Matsunuma, T [Conference-Abstract]

  Increasing traffic volumes on the major road corridors result in building up traffic congestion during the peak hours. Even in a congested road network, some route options are relatively lower congested while some are ...
• Identification of impact area, critical road sections and important intersections for traffic impact assessments 

  Jayasooriya, N; Jayathunga, K; Gamalath, I; Bandara, S; Weerasinghe, O [Conference-Abstract]

  In conducting traffic impact assessments (TIA), there are limited guidelines available to identify the impact area for proposed property developments. A circular buffer of a pre-determined distance is very common in ...
• Review of sampling strategies in QC and QA of asphalt surfacing and methods of acceptance 

  Jayasundara, V.; Mampearachchi, W. [Conference-Abstract]

  Sampling is a key component of any quality assurance (QA)/ quality control (QC) plan; it significantly affects the determination of quality and acceptance of work done. To determine density and compaction, core samples are ...
• Development of construction standard for semi-rigid pavement construction 

  Dahanayaka, I; Mampearachchi, W [Conference-Abstract]

  The drawbacks of the conventional Asphalt and concrete pavement mixtures such as rutting, cracks formation in modern construction practices have been given the tendency to discover an excellent composite mixer that achieves ...
• Use of the digital image analysis in determination of deterioration of thermoplastic road marking 

  Ranawaka, M; Bandara, S [Conference-Abstract]

  Road safety is a major component of the highway sector and it should be well considered in highway planning, designing, construction and maintenance. The visibility of road marking is essential for efficient traffic flow ...
• Development of evaluation criteria for routine maintenance work in performance-based road maintenance contracts
