“…Despite the relevance of multi-optimization stances to assess alternative solutions, existing works generally focus on road developments and reforms [4], including street constructions, lane additions, allocations and reorientations [15]. Zhang et al [24] seek non-dominated solutions for railway alignment considering costs and environmental impacts; Inti et al pursued [12] non-dominated road developments balancing environmental, economic and constructability factors; and Sohn [19] identified road diet network solutions maximizing utility for cyclists with minimum impact on motorists.…”

Ongoing traffic changes, including those triggered by the COVID-19 pandemic, reveal the necessity to adapt our public transport systems to the ever-changing users' needs. This work shows that single and multi objective stances can be synergistically combined to better answer the transit network design problem (TNDP). Single objective formulations are dynamically inferred from the rating of networks in the approximated (multi-objective) Pareto Front, where a regression approach is used to infer the optimal weights of transfer needs, times, distances, coverage, and costs. As a guiding case study, the solution is applied to the multimodal public transport network in the city of Lisbon, Portugal. The system takes individual trip data given by smartcard validations at CARRIS buses and METRO subway stations and uses them to estimate the origin-destination demand in the city. Then, Genetic Algorithms are used, considering both single and multi objective approaches, to redesign the bus network that better fits the observed traffic demand. The proposed TNDP optimization proved to improve results, with reductions in objective functions of up to 28.3%. The system managed to extensively reduce the number of routes, and all passenger related objectives, including travel time and transfers per trip, significantly improve. Grounded on automated fare collection data, the system can incrementally redesign the bus network to dynamically handle ongoing changes to the city traffic.

“…Recently, incorporating sustainability attributes in road design and construction processes considering all three aspects of sustainable development (i.e. environmental, economic and social) has gained traction in research (Inti and Kumar, 2020). One of the first and most prevalent definitions considers sustainability as “development that meets the needs of the present without compromising the ability of future generations to meet their needs” (WCED, 1987).…”

PurposeThis study explores the relationships among sustainability implementation barriers (resource, managerial and regulatory barriers), sustainability practices (sustainable construction materials, sustainable construction design, modern construction methods and environmental provisions and reporting) and sustainability performance (environmental, economic and social) in hill road construction (HRC).Design/methodology/approachPrimary data were collected from the 313 HRC practitioners with the help of a questionnaire, and research hypotheses were tested employing structural equation modeling.FindingsThe findings reveal a mixed effect of sustainability implementation barriers. Resource (managerial) barriers are negatively related to all practices except environmental provisions and reporting (sustainable construction materials), while regulatory barriers only negatively impact modern construction methods. On the other hand, all sustainability practices positively impact environmental performance, whereas economic (social) performance is positively influenced by all practices, except environmental provisions and reporting (modern construction methods), and positively affects economic performance.Originality/valueIn order to transform HRC toward sustainability, the barriers to sustainability implementation, sustainability practices and performance need to be understood by practitioners; however, the relationships have not previously been empirically assessed in extant literature. Besides, past research appears to be predominantly focused on the environmental aspect, thereby neglecting economic and social aspects. This study is a modest attempt to bridge these research gaps.

“…There are many issues faced by transportation agencies. Among these are the difficulty in determining the route for road alignment according to geometry and road design standards in different types of terrains [1,2]; the limitations of existing surveying measurement methods in providing accurate [3] and reliable information [4], especially in large areas and under thick canopies [5]; the inability to estimate the amount of cutting and filling in road earthworks [6] in order to select a road design that can provide optimal costs at the road planning stage [7,8]; the inability to produce a road design that can minimize the environmental impact, particularly in terms of natural river disruption [9], tree felling [10], wildlife settlement and the influence of landscapes on inhabitants' dwellings [11]; the inability to notice the risks and problems of an undulating terrain [12]; the inability to detect any slope failures [13] and the inability to provide access to other users in the road design when the topographic data are missing [14].…”

Perceived Usefulness of Airborne LiDAR Technology in Road Design and Management: A Review

et al. 2021

View full text Add to dashboard Cite

Airborne light detection and ranging (LiDAR) surveying technology plays an important role in road design, and it is increasingly implemented in the design stage. The ability of LiDAR as a remote sensing technology to be used in non-accessible places (i.e., hilly terrain, steep slope) makes it a powerful tool, and it has the potential to provide benefits that simplify existing design processes for designers and practitioners. This paper reviews the application of airborne LiDAR in road design and factors including items from the perceived usefulness of technology. The context of the future direction of LiDAR technology is highlighted in civil engineering road design, roadway inspection and as-built documentation. The implementation of this technology is expected to assist the end-users in developing more manageable planning for road construction and thus to ensure the usage of LiDAR technology is enhanced from time to time, especially in Malaysia.
