Item Expanding Landowner Adoption of Snow Control Measures Through a Better Understanding of Landowner Knowledge, Attitudes and Practices(Minnesota Department of Transportation, 2019-12) Current, Dean; Motschke, Collin; Serra, Airton Jr.; Wyatt, Gary; Zamora, DiomyPrevious research demonstrated the ability of snow fences to significantly lower both public and private costs related to the control of blowing and drifting snow. Follow-up research specifically addressed the knowledge of MnDOT staff and attitudes and practices related to the promotion and implementation of snow control measures. These efforts identified a need for a better understanding of landowners' knowledge, attitudes and practices related to snow control measures to develop more effective outreach and foster the adoption of snow control measures. We identified four regions of the state with highway corridors with snow problems. In each region, we carried out listening sessions with landowners and MnDOT personnel, and based on those sessions while applying the KAP (knowledge, attitudes and practices) methodology, we designed a landowner survey to explore landowner knowledge, attitudes and practices related to snow problems and the willingness of landowners to implement snow fences to address the problems. The survey was carried out once prior to an outreach effort and then again after the outreach effort to measure any changes in landowner knowledge, attitudes and practices resulting from the effort. We found that landowners were generally not aware of MnDOT's program to address snow problems and were able to identify constraints to adoption as well as incentives that might be required to promote adoption. We also identified the most acceptable channels for outreach to landowners as well as ways to better structure the MnDOT program to address constraints identified by landowners and provide the assistance and incentives needed to promote greater adoption.Item Rapidly Deployable Low-Cost Traffic Data and Video Collection Device(University of Minnesota Center for Transportation Studies, 2009-12) Schwach, Joey; Morris, Ted; Michalopoulos, Panos G.Transportation practitioners, planners and researchers lack the availability of an easily deployable, non-intrusive, portable, low-cost device for traffic data collection and video recording at intersections and arterials as well as temporary remote surveillance. The necessary data usually includes volumes, speeds, classification, turning movements, queue size and length, conflicting movements, and time headways. They also include recording of traffic characteristics, accidents and other special situations. A visual record of traffic characteristics at intersections, arterials, or other locations can also be used for extensive analysis and research leading to improved safety and control practices. In this report, the development and demonstration of a low-cost, practical, rapidly deployable video recording and data collection device is presented along with the design, deployment, and data extraction process. Its major advantage at intersections is that only one unit can cover an entire intersection up to 5 lanes per incoming approach wide (20 incoming lanes total), which should be sufficient for the overwhelming majority of intersections. In addition it has the potential of extracting turning movements automatically including optional lanes through advanced machine vision or radar sensors.Item Regional Optimization of Roadside Turfgrass Seed Mixtures Phase 2: Regional Field Trials and Economic Analysis(Minnesota Department of Transportation, 2022-07) Watkins, Eric; Christensen, Dominic; Yue, Chengyan; Moncada, KristineOur goal was to develop seed mixture recommendations to improve establishment and development of roadside vegetation in Minnesota. We selected 14 research sites across Minnesota and seeded 40 turfgrass mixtures. Turfgrass coverage was assessed at each site twice a year and the weed seed bank was examined. We found that greater seeded turfgrass species richness was important for increasing and stabilizing roadside turfgrass coverage across space. We also found differences in the type and density of the weed seed bank at many sites, but its impact was relatively low on weed coverage over time. We considered soil and weather variables and found three significant seeding clusters for Minnesota consisting of two geographical seeding clusters (north and central/south) and one non-geographical cluster for sites with poor soil quality. Three new mixtures for each cluster were recommended for Minnesota. Implementing these mixtures will reduce soil erosion, improve aesthetics, save local communities' financial resources, and improve the overall environment we occupy. As a complement to the field research, we developed cost prediction models that were incorporated into a detailed enterprise budget tool to calculate the roadside establishment costs that include labor, water, seed, sod, fertilizer, and other factors. This Excel-based tool can be used by local and state officials in determining budgets for roadside installations and which types or combinations of turfgrasses would be most cost effective, while also generating optimal performance.
