Autonomous Intelligent Warning Systems: Go Beyond Signs

Posted by on 16 Dec 2020 under Uncategorized

Written by: Michel Mondor

 

Vision Zero has become a rallying call in the traffic industry which has been embraced by municipalities across Canada.  We see large budgets and efforts being poured into improving safety which is very encouraging.  The challenge we often hear related to vision zero is that specific technology solutions to improve safety are not very prominent or available in the industry and that only a few options exist.  Radar feedback signs are one of the key technologies adopted; these systems have been proven to slow cars down by making drivers aware when they are driving at speeds above the posted limits.  The City of Toronto has installed hundreds of these signs as their primary traffic calming solution in order to battle vision zero over the past years.  They’ve now also introduced Automated Speed Enforcement systems, but those are still very new.

Written by: Michael McGuire, Stinson ITS Manager & Solution Architect 

Intro 

Over the past 10 years Central Management Software has emerged as one of the most critical elements of a smart cityespecially for transportation systems.  It used to be that connectivity was the biggest challenge for smart city designers; however, with the widespread adoption of 4G and fiber optic networks, municipalities have started taking the first big step.  With large infrastructure systems now widely interconnected and data from those devices available the next challenge has presented itself, what to do with all this information?  Central software is the easy answer but it’s a lot more complicated than that.  It will take a number of software systems to support these networks and they themselves will be interconnected in an ideal world.  Our focus today will be an innovative new player in transportation management software: Genetec Intelligent Mobility.

Vintage Smudge Pot

Work zones on roads have continuously evolved in the past century, from vintage smudge pots to warn drivers of dangers at night to modern reflective signs, cones, barriers, arrow boards and more. The term ”Smart Work Zone started popping up around 20 years ago and Stinson has been deploying them

 for the last 15 years; however, SWZwere never widely adopted due to a number of cost and technical challenges.  Due to recent advancements in technology and economies of scalewe’re beginning to see SWZs embraced in the market more and more. This has left me wondering whether Smart Work Zones are FINALLY starting to live up to their name and potential.  In this blog I’ll discuss the evolution of Smart Work Zones, where we see them going, and what the emerging benefits for safety, mobility and project management could be. 

The Evolution 

Electronic Arrowboard

Electronic Arrowboard

For years, a roadway work zone was merely an area delineated by traffic cones and traffic signs to warn drivers of its presence. They have been successful because they are highly visible, increase driver awareness and make drivers cautious. Most initial advances in smart work zones, such as flashing beacons and electronic arrowboards, revolved around the core concept of increasing visibility and conspicuity of the work zone.  

Portable Variable Message Sign (PVMS)

Portable Variable Message Sign (PVMS)

Temporary beacons and electronic arrowboards were a welcomed improvement to work zones however they needed to be powered by diesel generators, which were expensive and difficult to maintain. The evolution and subsequent adoption of cost-effective, reliable solar powered systems in the early 2000’s solved the problem of providing power to temporary beacons and arrowboards. Soon after portable variable message sign (PVMS) trailers powered by solar panels were introduced and quickly became a common sight oconstruction sites across North America. 

The start of Smart Work Zones began with the introduction of industrial cellular modems in PVMS, primarily to avoid having to manually program the messages at the roadsidebut also to provide remote monitoring and the ability to change the messaging in special cases and emergencies These cellular modems were initially quite expensive but the availability of low-cost modems and the continued drop in the cost of cellular data plans has heralded a revolution in cell modem use on almost all electronically controlled devices in the work zone.  For example, The Ministry of Transportation Ontario (MTO) has required cell modems in all their work zone PVMS for many years now. 

Since about 2014 it seems that advances in sensor technologies, material sciences and software has unlocked many innovations in smart work zones. Through combining these new sensors and software with traditional PVMSSmart Work Zone concepts and aspirations that had been talked about for years have now become feasible and practical. Now CCTVs, microwave sensors, radar sensors, Bluetooth/Wi-Fi sniffers and many other sensors are an integral part of Smart Work Zone systems adopted in Canada.  Some of the most popular smart work zone systems we’ve seen emerge over the past 5 years are: 

  • –  Temporary queue end warning systems 
  • –  Travel time advisory systems 
  • –  Truck entrance / exit warning systems 
  • –  Work zone speed monitoring and  
  • –  Incident detection and surveillance systems 

Going forward, there seems to be a much greater focus on data collectionmapping app integrations and traffic signal optimizations to minimize congestionThe Greater Toronto Area has seen a number of large Light Rail Transit projects launched over the past few years with many more planned. These are huge projects which disrupt traffic on major arterials for 5-10 years which, as you can imagine, has a huge impact on congestion.  As a result, we’re seeing an increased focus on advanced traffic signal optimization and extensive multi-modal data collection. Both are used to reduce congestion as well as identify safety concerns related to pedestrian and cyclist movements within the work zone. The data has also been used by agencies to determine strategic lane closures and construction activity based on actual measured road conditions opposed to traditionally static time windows. This has been especially useful during COVID-19 because agencies took advantage of reduced traffic volumes that were detected by SWZ solutions when people started working from home.  

Today, Smart Work Zones provide unprecedented accuracy, reliability and real-time traffic control at large work zones through advanced sensors, edge processors and cloud-based software. SWZ systems have also evolved and matured to a point where the systems are very simple to deploy, maintain and connectThis simplification has encouraged contractors to embrace these technologies more than ever before.  

 

The Benefits 

For Road Users 

The focus of Smart Work Zones is no longer solely to make road drivers aware of the work zone boundaries, they go beyond, and provide more contextual and useful information. SWZs are now connected systems which relay accurate, real-time information including when a work zone is active (i.e. construction workers are present)the expected delay using travel time systemsas well as alternate route suggestions on map apps such as Waze and Google maps. New generation road users tend to trust this live information more than traditional signs and cones, and thereforethese systems help them plan alternate routes and make drivers more aware and cautious.  A focus has also been placed on vulnerable road users such as pedestrians and cyclists, often providing dedicated lanes and sidewalks for them to ensure their safety.   

For Traffic Managers 

The jury is still divided amongst traffic managers in Canada regarding the best configuration of Smart Work Zone systems for different types of road construction activities. Time travel systemsCCTV monitoring and queue-end warning systems are now common in most highway and major road work zones.  

Traffic managers are now increasingly advocating for the use of technology to monitor safety and compliance in work zones. Speed compliance monitoring, traffic volume monitoring and CCTV surveillance are their first choice to ensure incident monitoring and compliance. Efforts towards shared responsibility and transparency by sharing road data (including work zone data) with emergency services, environmental agencies, and contractors is becoming more common. Smart Work Zones play an important role in generating, collecting, and sharing accurate reliable data with all stakeholders. 

For Construction Managers 

Believe it or notconstruction managers are the biggest beneficiaries of Smart Work Zone systems. Not only do these mature, easy-to-use systems help comply with mandatory project requirements, but they also provide tools to monitor & measure safety conditions throughout the work zone. Modern SWZ systems collect data that allows construction managers to make informed decisions 

We worked with one of our customers, a primary contractor of an LRT corridor in Toronto, to deploy one of the most advanced Smart Work Zones in Canada. Through extensive data collection and reporting they’ve been able to use factual, reliable weekly traffic volume data to get additional lane closures approved during COVID-19 while maintaining similar travel times for road users. The contractor is also testing advanced video analytics technology to monitor changes in traffic, pedestrian and cyclist volumes as well as to perform traffic signal optimization and incident detection along a heavily congested corridor within the work zone.   

The success of these projects gives us a preview of what we can expect in the future for Smart Work Zone technologies in urban areas. Universities such as Ryerson University are now actively studying the impact of dynamic staging in work zones on traffic. We at Stinson ITS are proud to be associated with these studies, projects, and unique use cases at the forefront of Smart Work Zone innovation and adoption in Canada. 

The Future 

Reliable, easy-to-use Smart Work Zone systems, which help improve safety, user convenience and compliance in a work zone through transparent sharing data, information, and responsibilities between all stakeholders of road construction, will lead the future roadway work zones. There will be continued adoption of both stand-alone and holistic connected work zone systems which provide data to help drive decisions on construction zone layoutslane closures, compliance, alternative routes, and reducresponse time of emergency services. 

Connected and automated vehicles are also opening new possibilities for Smart Work Zone systems and we predict that communicating safety-critical messages directly to the vehicles from work zones would be a major area of innovation in the future.

Navtech Radar: Paving the way for safer, smarter roads in Canada

Posted by on 18 Sep 2020 under Uncategorized

 

Canada has over 1 million kilometers of roads38,000 kilometers of which are highways. Despite extreme cold weather and low population density, Canada maintains a wide network of high-quality roads. Canada is ranked 31st out of 141 countries in terms of quality of roads, much higher than Norway (49th) and Russian Federation (99th) facing similar weather and population density (World Bank, 2019).  

Canadian highways also face some unique challenges. Many Canadian highways travel through wildlife reserves, consequently making wildlife collisions fairly common riskCanada is also home to North America’s busiest highway – Highway 401 which holds the record for worst pileups in Canadian history due to high vehicle speeds and extreme winter weather conditions. Winter weather conditions such as snowy and icy roads as well as lack of visibility are also responsible for almost 30% of vehicle accidents in Canada.  

Canadians also spend an awful lot of time commuting to work, especially in large cities such as Toronto, Vancouver, and Montreal. Approximately 17% of GTA residents spend over 70 minutes commuting every day.

The Power and Promise of Smart Cities

We believe a smart city should keep citizens safe with streets that improve mobility for all modes of transportation. A smart city should actively employ strategies to reduce greenhouse gas emissions and congestion, leading to improved air quality. Furthermore, a smart city should own its own data and use it to empower collaborative innovation among city departments, partners, academia, and developers who use that data to create innovative solutions to everyday problems. Once you’ve decided to make your city smarter, often the most difficult part is knowing where to start.
