Accessibility evaluation system for site layout planning – a tractor trailer example

Abstract

Background: Accessibility is a critical issue in site planning. A good accessibility plan can avoid possible conflicts involving equipment and allows for smooth transportation during the entire project. It can also ensure that sufficient space is available so that all onsite equipment, such as trucks, cranes and excavators can be safely operated. In current practice, the evaluation of accessibility is done manually, relying heavily on the experience of the construction planners. However, the evaluation needs to deal with temporal and spatial information simultaneously, which make the manual evaluations very challenging.

Construction 4.0: a survey of research trends

“…Simulation enhanced through holographic technology, for instance, and rapid prototyping with 3D-printed models speeds up design iterations and improves visualization. Simulation and visualization also help construction planners to identify potential accessibility problems and unsafe situations on construction sites and avoid them early in the design and planning stages (Lin et al, 2013). For example, transportation processes can be simulated in an interactive, realistic virtual environment to identify potential safety and accessibility problems of the site layout plan.…”

“…As a result, technologies in the construction phase have been mainly developed to deal with applications such as safety inspection (Oesterreich and Teuteberg, 2016;Tezel and Aziz, 2017), site monitoring (Dallasega et al, 2018), process efficiency improvement (Monizza et al, 2018), and measurement of production volume and calculation of productivity (Woodhead et al, 2018). The body of research on the application of mobile devices for real-time data collection (Dubas and Pasławski, 2017;Hu et al, 2018;Laine and Ikonen, 2011;Whyte and Hartmann, 2017) is growing rapidly, and numerous types of mobile devices and communication devices, such as global positioning systems (GPS) (Tezel and Aziz, 2017) and RFID devices (Dallasega et al, 2018;Ehrbar, 2016;Lin et al, 2013;Oesterreich and Teuteberg, 2016;Wang, 2013;Woodhead et al, 2018), are already in use on construction sites.…”

Construction 4.0: what we know and where we are headed?

“…This method helps in understanding and identifying the safety hazards due to ignorance or inadequate precautions. Similarly, optimal travel path identifications were also demonstrated utilizing such platforms to visualize the accessibility and conflict between tractor-trailer movement at a construction site (Lin et al, 2013). Often, these platforms are combined with simulations backed by multiobjective optimization algorithms to achieve desired objectives (Singh, Patil and Delhi, 2019).…”

A Typology Model of Temporary Facility Constraints for Automated Construction Site Layout Planning

“…Third, iterate the second step until sweeping is completed. The set of these triangles is the visibility regions from the viewer's point where the segment hidden from the viewer due to the presence of other objects is considered [46]. Furthermore, when a closed-circuit television (CCTV) is installed to cover the visibility, it should also be deemed a viewer that creates a visibility region.…”

“…This may be because gates often have a priority in CSLP due to their impact on materials and equipment logistics, traffic outside the site, and civil complaints. On the other hand, constraints of access roads (e.g., VI1 and DI3) often require vehicle movement information, which is difficult to track without the help of a computer, such as vehicle turning radius, vehicle width, and vehicle safety buffer zone [46]. Compared to other facilities, laydown areas, storages, work areas, toilets, and parking lots also have constraints that are worth considering but not actually considered in practice.…”
