DMD is committed to reducing impacts to vulnerable road users via improved street lighting design. As such in the late summer and early fall DMD will be directly involved with a number of significant NCHRP roadway lighting research projects. These projects will have a significant impact on visibility and how roadway lighting is best applied to improve safety. We will keep you posted. Refer to the link below for some very significant lighting road safety research undertaken some of which was co-authored by DMD including research Report 940 and the 2012 & 2023 Light Handbooks & the Web-based training for FHWA Roadway Lighting Workshop. ...

The Steveston Interchange project is a key part of the Highway 99 Tunnel Program to improve travel along the Highway 99 corridor. As part of the broader program, the new Steveston Interchange will improve connections for vehicles, transit users, pedestrians, and cyclists. Opening in 2025, the modernized interchange will provide more vehicle lanes, improve transit operations, and include sidewalks and cycling lanes on both sides of the structure for the first time. The project includes replacing the existing two-lane interchange at Steveston Highway and Highway 99 with a five-lane structure. The new structure will include two eastbound lanes and three westbound lanes, including a left-turn lane onto Highway 99, to improve traffic flow. Improved ramp connections between Steveston Highway and Highway 99 to improve traffic flow and reduce queuing for vehicles. There are several transit-priority measures to allow buses to move through the interchange more efficiently, including signal priority at intersections, and a dedicated transit lane and in-lane bus stop in the northbound offramp. As of June 2023 DMD has completed the design for the lighting signals and ITS system for the interchange. Key elements included design electrical, lighting, signals and ITS systems modification to the existing ITS and counterflow system, interface with BC Ministry of Transportation, TI Corp and the City of...

The way we light roads and streets can greatly impact visibility and improve safety. Don McLean presented new and evolving research to the committee focused on improving pedestrian detection distance for drivers. The research undertaken by DMD, WSP (US), VTTI and the US Federal Highway has great benefit in reducing fatalities of vulnerable road users....

“Construction of Playland’s next new ride is ON TRACK!” a social media update reads, noting the new attraction will be “Canada’s fastest launch coaster.” The $9 million ride is slated to open in the summer of 2024. The Zamperla ride will feature an opening tunnel, an 18-metre drop, airtime hills, helices, and sweeping turns. The track is expected to be an estimated 380 metres, with a 1.3 G launch acceleration. DMD prepared electrical, lighting and communication design services for this project. DMD worked closely with the PNE and the ride manufacturer to provide power supply to the ride as well as a design for an eHouse electrical room to house the electrical distribution and ride control equipment. The state of the art propulsion system for this ride reduces the size of the electrical service by making use of a large bank of supercapacitors to provide the large surge of power required to LAUNCH the coaster from a dead stop! In addition to the ride design, DMD provided Thematic lighting and AV design for the surrounding ride area including the plaza and queuing areas. The thematic lighting is fully DMX controlled colour changing technology for unmatched rider...

Under contract with Texas A&M Transportation Institute (TTI) Don McLean (DMD) co-authored and co-delivered an in-depth 3-day roadway lighting training course to senior FHWA road safety staff. The training course included information ranging from basic fundamentals to more advanced design methods to improve visibility. Upon the completion of the workshop/training, the participants had a basic overview of the fundamentals; such as theory, technology, standards, so the participants can provide technical assistance to State and local DOTs and convey safety messaging related to roadway lighting. The workshop was held at the Virginia Tech Transportation Smart Road Facility in Blacksburg, Virginia. High-time visibility demos based on the current research were reviewed via the Smart Road Lighting System. Following this workshop, a training guide will be developed and issued to...
