Can recycled glass help improve road slip resistance?

ARRB, 27.10.2021

A new test is currently underway to find out if recycled glass can be used to provide safer and more slip-resistant roads.

The State of Victoria has allocated for ARRB and OmniGrip Direct $81,000 in project funding on whether recycled crushed stone can be mixed with other aggregates to provide road surfaces with higher slip resistance than ordinary surfaces.

It is hoped that the use of locally produced recycled glass will reduce the amount of crushed and processed aggregate, reduce the cost and reuse crushed stone destined for landfill to support a closed-loop economy.

The one-year project is expected to be completed by the end of September 2022.

The ARRB/OmniGrip Direct project is one of 10 funded under Recycling Victoria Research Foundation for Materials to increase confidence in the use of recycled materials in everyday products and increase demand.

Project Details

Title: Surfacing with higher friction for road safety, including recycled glass

Background

OmniGrip Direct is a company that develops and applies various technologies to eliminate black spots on the roads.

Such road surfaces have better sliding properties than typical bitumen-based surfaces. They are used as safe procedures to apply to accident black spots and high-risk locations to improve grip for all road users.

OmniGrip Direct uses Australian recycled glass as well as calcined bauxite within the existing range of procedures.

Project objective

This project is aimed at whether recycled crushed stone can be mixed with slip-resistant aggregates and binders to provide a new road safety surface made of recycled glass.

The project will assess the friction characteristics of a number of mixtures against the control asphalt pavement and traditional calcined bauxite.

Samples will be prepared. The friction properties are evaluated. They will then go through simulated wear mode to make sure they meet the performance requirements.

This project was funded by the State of Victoria ($81,000).

This work is scheduled to be completed in November next year.

Iteris launches managed services for Intelligent mobility infrastructure

Traffic Technology Today 26.10.2021

Iteris has announced the availability of two new cloud-based managed services that complement the traffic management operations of government agencies and commercial enterprises. Iteris managed service offerings use its ClearMobility platform to proactively manage complex transportation operations, resulting in reduced traffic congestion, improved safety, and a more sustainable, fairer, and more resilient transportation infrastructure.

The Iteris Congestion Management Service for intersections and motorways facilitates continuous analysis of traffic trends along signal corridors and motorway construction projects. It also identifies areas of improvement and optimizes signal timing along corridors to help improve mobility and reduce congestion for municipalities, cities and states.

As part of the congestion management service, Iteris applies its industry-leading software-as-a-service (SaaS) suite of solutions, including the ClearGuide transportation performance solution, to continuously analyze and visualize traffic data to improve safety and mobility, as well as to implement remedial measures as needed. changes in traffic conditions. Initially, the congestion management service is focused on operating traffic lights and maintaining traffic on motorway construction projects, but it is expected that it will be developed to consider additional use cases.

The Iteris asset management service allows transportation agencies to monitor and maintain the inventory and condition of process equipment deployed locally or in a warehouse, conduct life cycle analysis and monitor asset performance over time. The Iteris asset management service improves the uptime of the traffic sensor to improve overall operation, as well as traffic light management and intelligent transport systems (ITS).

Early followers

In July 2021, the City of Lake Forest selected Iteris for a multi-year intelligent mobility program, under which Iteris will provide its congestion management services to expand the city's traffic management operations to reduce congestion and improve safety throughout Lake Forest, California.

In March 2021, the Pulice-FNF-Flatiron joint venture selected the Iteris congestion management service for highways to increase mobility and safety for the strategically important I-10 Broadway Curve Design Build highway improvement project. Also in March 2021, the OC 405 Partners joint venture expanded the use of ClearGuide for another year as part of the Iteris congestion management service to manage and minimize the impact of construction on traffic jams, safety and mobility of 370,000 daily Southern California drivers during the I-405 improvement project, which was launched in 2017.

Additionally, the Georgia Department of Transportation has selected Iteris Asset Management Service to improve ITS statewide service following the successful deployment of a similar ITS asset management system for the Virginia Department of Transportation (VDOT). This new service will expand Iteris asset management with tens of thousands of ITS highway assets to include 4,500 traffic lights across the state.

"These innovative new cloud-based managed congestion management services enable cities and states to increase safety, mobility and road user satisfaction to a greater extent than can be achieved using traditional methods, while reducing carbon emissions for better air quality," says Scott Carlson, vice president of alternative supply at Iteris. "Based on the positive results of early adopters, we are pleased to officially launch these new solutions."

Iteris congestion and asset management services are key components of the ClearMobility platform. ClearMobility applies cloud computing, artificial intelligence (AI), advanced sensors, consulting services and managed services to ensure road safety and travel efficiency.

Dhyan Networks and Technologies has announced that the city of Portland, Maine has successfully transitioned to the StreetMan system, Dhyan's state-of-the-art cloud-based central management system (CMS) to manage its smart street lights.

StreetMan 's cloud SaaS product is independent of technologies and vendors, with built-in support for several industry standard protocols such as TALQ, OSCP, MQTT, HTTP and communication technologies such as Zigbee, LoRa, NB-IoT, Powerline, Cellular, etc. This allows cities and municipalities to manage and monitor various smart street assets such as street lights, cameras, access points, charging stations, billboards and Internet sensors.

Extended functions StreetMan allowed the city to optimize the distribution of controllers between gateways, which led to a more reliable radio frequency network and the ability to isolate faulty controllers from those with communication problems.

"They were able to do it completely remotely, thousands of miles away, without a single visit to the site," says John Jennings, Portland city manager. "This partnership helps us further achieve our Sustainable Development goals, as well as reduces costs and achieves efficiency. Our team members can now diagnose problems from their desktop computers and share this information with our technicians so that they are fully prepared to carry out the necessary repairs on the ground. "

"Street lights are one of the biggest expenses for any city," says Prakash Ramadasts, vice president of smart cities in Dhyana. "Converting street lights from old technology to LED lights can save a lot of money, but by adding intelligent controllers and a sophisticated centralized control system like StreetMan, the savings can be increased even further by giving the city the ability to dim street lights on demand and allowing them to perform proactive maintenance."
