Hosted by Edouard Proust, this webinar presentation by David Bevly held on February 10, 2021 highlights an important component of FPInnovations' Transportation and Infrastructure group's work. The concept of truck platooning, inspired by pelotons of cyclists and originally developed for highway use to obtain fuel savings, utilizes technology to maintain the desired distance between trucks by controlling acceleration and braking, and the relative lateral position of the vehicles by steering, reacting faster than a driver can. Truck platooning has attracted the attention of the natural resources sector and its implementation is expected to increase the productivity of drivers. By allowing the operation of driverless following trucks replicating the path set by the human operated leader vehicle, the concept could help mitigate the workforce shortage that impact the sector while supporting the supply of lumber to mills across the country.

Cette présentation de David Bevly a été organisée le 10 février 2021 par Edouard Proust. Elle met en lumière une composante importante du travail effectué par le groupe Transports et Infrastructures de FPInnovations. Le concept d’opération de camions en peloton est inspiré des pelotons de cyclistes et a été mis au point à l’origine pour des applications autoroutières avec pour objectif une réduction de la consommation de carburant. Les camions sont équipés d’une technologie permettant le contrôle de l’accélération, du freinage et de la direction offrant la possibilité de maintenir la distance de suivi entre les véhicules ainsi que leur positionnement latéral relatif. En autorisant la mise en œuvre de camions suiveurs entièrement autonomes et qui répliquent le tracé du camion de tête opéré par un chauffeur, le concept pourrait à terme aider à minimiser l’impact du manque de chauffeurs dans l’industrie tout en supportant l’approvisionnement en fibre des scieries à travers le Canada.

This report presents the importance of best management practices for mitigating erosion from resource roads and preventing sediment from entering a watercourse. Key to achieving these goals is the understanding of erosion from the road surface and the level of connectivity from the delivery point of the sediment-laden water onto the forest floor and the watercourse. This report provides a list of best management practices that is specific to resource roads.
Intelligent transportation system safety applications such as an approaching vehicle emergency warning, co-operative collision warning system, and co-operative adaptive cruise control, may have potential to improve road user safety on resource roads. This report documents a feasibility study of these safety applications under the operating environments and road conditions of resource roads. This report found that existing safety messages could be tailored to the needs of resource road operations. Two safety-related use cases
(i.e., oncoming vehicle warning and one-lane bridge warning), and two non–safety-related use cases (i.e., platooning and teleoperation) are presented.

Forest operations across Canada are encountering increasingly difficult road conditions and more frequent access interruptions related to wet and weak road sections. Resource roads are considered a liability by many forest companies and their business model has been to create the lowest cost, lowest standard, resource road network possible that also will provide tolerable levels of access (i.e., some but not too many failures and hauling disruptions). Increasingly difficult operating conditions and frequent access interruptions, however, drive up costs and threaten the economic sustainability of forest operations.
Starting in 2017, FPInnovations has launched a project to provide its members with techniques and strategies that will offer more reliable and strong road sections and reduce overall road costs. A state-of-practice survey of FPInnovations members provided researchers with a comprehensive understanding of conventional means of responding to wet, weak road conditions in Canada. The report summarizes the responses to wet, weak resource road sections that were identified in the state-of-practice survey and provides an overview of the chief causes and related site indicators for wet, weak road conditions.
Recommended best practices are provided for a variety of conventional industry responses to wet, weak road sections. These address common misconceptions and knowledge gaps that reduce the effectiveness and increase the overall cost associated with the industry responses. These best practice recommendations were based upon findings from a literature review, product manufacturer information, and from researcher expertise.
The report also considers improvements to conventional practices, and advanced solutions that are potentially more effective and economic than the state-of-practice but are not widely exploited by industry. Eleven potential solutions from these two categories were compared and ranked in order of potential. The practice improvements selected for further study were soil compaction, and corduroy and access mats. The advanced solutions selected for further study were geosynthetics that offer both soil reinforcement and enhanced drainage, geocells, and TPCS, a technology to improve truck road-friendliness. Starting in 2021, FPInnovations will initiate field trials and life cycle cost analyses of these technologies.
A methodology was developed to evaluate the performance of different commercially available siding materials when exposed to high and low radiant heat loads. The materials evaluated in this study were engineered wood, fibre cement board, cedar siding, and vinyl siding. The time to ignition of the wall prototypes was used to evaluate the performance of these materials.

Canadian regulators utilize the ESAL concept for vehicle impact evaluations and(or) pavement design. Unfortunately, TAC’s ESAL equations do not account for tire size and, consequently, overestimate steering axle impacts when those axles are equipped with widebase steering tires. Many new vehicles proposed for use in Canada feature tridem-drive tractors and heavily loaded steering axles—these heavy loads necessitate the use of widebase steering tires. In order to optimize high efficiency truck configurations in Canada, therefore, accurate estimates of widebase steering tire ESALs are needed. This work describes a methodology to estimate ESALs for widebase steering tires. These ESAL equations were used to justify an increase in steering axle weights for B.C. 9-axle log B-trains.
Given the benefits that resource roads provide to economic and social well-being, it is important to understand the impacts of a changing climate on resource roads and infrastructure. As the forest industry and governments move toward creating resource roads that are resilient to climate change, an early step in the adaptive management process is to assess the risks and vulnerabilities of infrastructure to climate change.
As part of FPInnovations’ and BC Forest Safety Council’s ongoing evaluation of fatigue management technology, Seeing Machines’ Guardian Gen 2, an eye-tracking–based driver assistance system that monitors driver fatigue and distraction, was evaluated in Interior B.C. log-hauling operations. In addition, driver fatigue scores based on a wristband technology, Readiband, were correlated with the drivers’ reported scores to verify the fatigue level in the participating fleets. The study findings, participants’ feedback, and onboard device performance are summarized in this report.
Évaluation du Guardian, le système embarqué de surveillance de La Fatigue de 2e génération de Seeing Machines, dans le cadre des activités de transport de billes dans l'intérieur de la Colombie-Britannique
Dans le cadre de l’évaluation en cours des technologies de gestion de la fatigue réalisée par FPInnovations et le Conseil de la sécurité forestière de la C.-B., le Guardian de deuxième génération de Seeing Machines, un système de suivi des mouvements des yeux qui surveille la fatigue et la distraction chez les conducteurs, a fait l’objet d’une évaluation lors des activités de transport de billes dans l’intérieur de la C.-B. De plus, les pointages de la fatigue des conducteurs, établis selon le bracelet Readiband, ont été corrélées avec les pointages déclarés par les conducteurs afin de vérifier le niveau de fatigue chez les conducteurs des flottes prenant part à l’évaluation. Les résultats de l’étude, la rétroaction des participants et le rendement du dispositif embarqué sont résumés dans le présent rapport.

FPInnovations was approached to investigate the extraction of tannin from tree bark in British Columbia (BC). FPInnovations has been working on bark extraction over the last few years and
proposed to focus this study on Western Hemlock which showed high tannin content in previous work. The extraction method developed by FPInnovations uses chemicals and elaborate
equipment that requires the work to be conducted under strongly controlled conditions, such as a chemical laboratory. This report aimed to find a simpler extraction protocol that could potentially be used by coastal First Nations communities or other parties interested in extracting tannin from bark at a relatively small scale.
This guide is intended as a reference for use during the eld data collection phase of the provincial process in assessing sh passage at culverted sites.1 It is an important part of the provincial assessment process which uses a holistic watershed approach. The eld data can be used as part of the development of a sh passage restoration plan2 or as part of regular road maintenance inspections.
The main objective of the present work is to respond to the second work area and complete LCAs focused on resource roads and transportation products and processes. Two LCA studies will be conducted; one study on resource road bridges and one study on hybridization of logging and biomass trucks. The present report undertakes an LCA of three resource road bridges.
