The Regional Traffic Signal Synchronization Project (CV Sync) is Coachella Valley Association of Government’s (CVAG) major effort to advance the development and implementation of intelligent transportation systems (ITS) and Smart Region Programs with an emphasis on the development of multi-jurisdictional and regional smart intersections, smart corridors, and broadband communication networks. The region will become smart cities ready through a high-speed secured communications network. This will be achieved by fitting intersections along 25 corridors with the latest advanced traffic signal controller units, cellular vehicle-to-everything (C-V2X) roadside units, ITS technologies, and a secured communication system. CVAG will be deploying connected vehicle technologies, including signal phase and timing (SPaT) and other basic safety messages via a vehicle onboard unit that will communicate with the roadway infrastructure.
The Margaret Turner Storm Drainage Improvement project consists of a 145-acre watershed located in northwest Charlotte, North Carolina, near Brookshire Boulevard. Charlotte-Mecklenburg Storm Water Services (CMSWS) identified this area for study and improvements due to reports of road flooding and residential structure flooding in the Margaret Turner subdivision. CMSWS partnered with The Isaacs Group P.C. to complete the planning study, design, public outreach, and construction administration services. Drainage improvements within the project area included a 13-foot by 4-foot reinforced concrete box culvert, a 42-inch pipe culvert, and natural channel improvements. Due to the space constraints, a detailed shoring plan for storm drainage construction was developed to protect existing infrastructure and install the new system. The design included extensive relocation of existing utilities and utility coordination during construction to reduce the disruption of services to the residents in the neighborhood.
Each community seems to have that one spot that always has crashes when winter weather arrives, or bridge that behaves differently than all the others at night. Why is that?…
One of the core jobs of the fleet manager is to make sure fleet assets are provided in a cost-effective, efficient manner. Having a solid, reliable basis for determining those…
This CLL will look at emerging technology for signal control systems that can identify bike and pedestrians’ movements and log this data both locally and in the cloud. The session…
When snowflakes fly residents get worried. “Can I make it home?” “Where are the plows?” “When are they going to plow my street?” Clear and effective communication keeps residents informed and eases the anxiety that winter storms bring. In this session the speaker will demonstrate the importance of effective policy and procedure, and how that helps manage information. Using his own experience, the speaker will make the session practical by focusing on road condition information during a winter storm. He will lead a discussion regarding effective channels for distributing information to the public; show how his county uses SharePoint to maintain updated road condition information, and describe how using low-cost software can empower staff and others to collect road information.
High Friction Surface treatments include a two-part application of an epoxy binder followed with placement of rough, hard, and durable aggregates on an existing roadway surface. These treatments reduce roadway departure accidents by increasing surface friction. Promoted by PennDOT and the Federal Highway Administration, Allegheny County has used this treatment for the past few years and found it is a cost-effective safety treatment for strategic locations on roadways where friction needs to be maximized (such as steep grades or sharp horizontal curves). It provides texture to existing concrete or asphalt surfaces without sacrificing uniformity or rideability. Other public works agencies may find this treatment has value for their own assets.
Like many cities, the City of Charlotte, North Carolina, faces the challenge of aging infrastructure in urban environments serving an ever-growing population. This presentation will present two case studies related to expedited temporary repairs the City undertook that employed innovative solutions. The first case study will examine a temporary bridge used to remove traffic loading from a compromised existing culvert that serves a center-city thoroughfare before the planned Republican National Convention and impending NFL season. The second case study will focus on an existing corrugated metal pipe that experienced a significant joint failure and the measures taken to protect the public and restore traffic in an accelerated manner. The presentation will include a summary of the challenges associated with each project and lessons learned.
Emergencies are equal opportunity challenges in communities as they impact citizens with and without disabilities. It is vitally important that communities prepare well before emergencies occur with practical and well-thought-out solutions that keep everyone, including those with disabilities, safe while maintaining their dignity at all times. Information will be provided regarding how to plan for individuals with specific needs, including mobility, visual, hearing, and cognitive impairments, and for people whose survival requires medical equipment. Accessible evacuation plans and shelters will also be addressed, along with laws regarding service animals. Attendees will learn about questions that can and cannot be asked of people with disabilities and about politically correct disability-related terminology.
As per-and polyfluoroalkyl substances (PFAS) discoveries increase across the country, water utilities, industry organizations, state regulators, and the EPA are struggling to publicly communicate new findings in drinking water, wastewater discharges, and biosolids. And these discoveries are going to exponentially increase in the coming years. The EPA’s Fifth Unregulated Contaminant Monitoring Rule (UCMR 5) will require most water utilities across the country to test for 29 different PFAS compounds starting in 2023. Make no mistake, obtaining this data is absolutely necessary to our industry as we play catch up with the decades-long damage to our source waters. However, as we look for more PFAS, there is still so much we don’t know about the health and environmental impacts of the vast majority of these chemicals.
