FHWA and EPA National Near-Road Study Las Vegas

9 Lessons Learned

Costs, timeliness and other operational factors are just some of the site implementation variables that may be difficult to control. These implementation variables include site access and permissions, electrical connectivity, security, communications, site operators and equipment. Costs may be estimated but there may be factors beyond one's control that influence the outcome of the costs. An example of this was that in order to obtain electrical services for the Las Vegas study site, electrical conduit needed to be installed underground. This underground installation encountered a caliche geological formation, i.e., hardened sedimentary rock prevalent in the Las Vegas area. This necessitated the use of jackhammers to install the underground conduit; a much more expensive operation than the use of the typical backhoe. An additional example was the performance of an analytical instrument utilized in the study. This instrument had both design and manufacturing issues that only became apparent after the instruments had been deployed. The remedy for this situation was that the manufacturer performed an “in the field upgrade”. Projects of this nature present myriad challenges both from a programmatic and technical perspective.

Access to sites owned by private citizens can be challenging. Adjacent property owners may understand the necessity of improving the state-of-the-science, benefiting the community at-large and have a desire to be a “good” citizen, but existing lease and financial issues are a deterrent to participation. In addition, liability, insurance compensation, hassle factor(s), and other real and perceived issues present obstacles to site access.

Electrical and communications companies have numerous requirements for obtaining their services. This process requires interactions with utility companies as well as local (i.e., county or city) inspections departments.
