Air Quality & Weather Systems

Messaging solutions provider SESA recently signed an agreement to develop NTCIP compliant lane control signs (LCS) incorporating a conflict monitoring system as a vital design criterion. This system will automatically change lane signals that correspond to the counter flow mandate. In multi-lane counter flow commute lanes, if a green arrow is displayed on one LCS, the LCS on its reverse must display a red cross. Timing on all LCS signs will be identical. Additionally flashing red crosses will be in

The Michigan Department of Transportation’s (MDOT’s) Automated Vehicle Location (AVL) and Maintenance Decision Support System (MDSS) Program - designed and implemented by Delcan Technologies, a Parsons company, in partnership with Iteris - recently received the Best of ITS award from the Intelligent Transportation Society of America (ITS America). Honoured as the Best New Innovative Practice in the Sustainability in Transportation category, MDOT was recognised for the program’s leading-edge technology as we

Four of the latest variable message signs (VMS) are to be installed around junction 35 of the M6 motorway at Carnforth, giving drivers better warnings of incidents and other information about the motorway such as weather conditions. As part of the work, new CCTV cameras will be mounted on the VMS signs and standalone masts, allowing Highways Agency traffic officers at the North West Regional Control Centre at Newton-le-Willows to monitor and manage motorway incidents more effectively. A similar, US$2

A report on the role of speed in vehicle crashes in New South Wales (NSW), Australia, makes a number of recommendations to isolate speed as a causal factor in crash rates by improving data collection and conducting specific research to identify the triggers for speeding, particularly in rural and regional areas. The report, by the Joint Standing Committee on Road Safety (Staysafe) also looks at the appropriateness of speed limits and approaches adopted in other jurisdictions and the adequacy of existing

Colin Sowman catches up on some of the latest research around outdoor pollution and looks at options available to authorities in areas of poor air quality. Iair quality hasn’t already reached the top of the agenda in transportation department meetings in your area, it probably soon will with national, trans-national and even global bodies calling for authorities to reduce pollution levels.

Developed by MVIS and its partner, Intellicone temporary work zone safety system creator, Highway Resource Solutions (HRS), the over-height detection solution is part of the partners’ work-zone safety portfolio, the first temporary

The Virginia Department of Transportation (VDOT) has begun work on installing an active traffic management |(ATM) system on interstate 66 through Arlington, Fairfax and Prince William counties from the Washington, DC line to Route 29 in Gainesville. Designed and built by TransCore, the system is intended to improve safety and incident management and will include new sign gantries, shoulder and lane control signs, speed displays, incident and queue detection, and increased traffic camera coverage.

One of the most challenging road construction and ITS projects currently underway is the upgrading of the road from Bogota to Villavicencio. Currently it takes four hours to make the 86km journey between Bogota and Villavicencio using the existing single lane in each direction road which passes through some very challenging terrain. It is the only ground connection between central Colombia and the eastern region which represents 40% of the country’s territory.

Swarco Traffic Americas is to install new parking guidance technology in a ten-level parking garage for Monarch Casino Black Hawk in Black Hawk, Colorado. The system involves a combination of single space monitoring as well as indoor and outdoor garage variable message signage. Each parking space will be monitored by 1,265 state of the art ultrasonic sensors above each parking space to detect vehicles as they park. Vacant spaces are indicated by LED lights. Space availability data from the sensors will t

The Arkansas State Highway and Transportation Department (AHTD) has selected Iteris’ cloud-based maintenance decision support system (MDSS), ClearPath Weather, to provide state-wide weather forecasting services for improved winter road maintenance response. ClearPath Weather will provide AHTD with web-based access to high-resolution pavement weather forecasting and treatment alternatives at designated locations around the state during winter weather events. Additionally, AHTD will have available use of I
