The Challenge
The US 50 corridor in Pueblo, CO faced erratic and unpredictable traffic conditions, exposing the limitations of traditional time-of-day signal timing. The corridor primarily serves commuters during the week and recreational travelers on weekends, with traffic patterns influenced by school schedules, tourist activities, and weather conditions. The eight-mile project area included 10 signalized intersections and experienced significant congestion levels. Traditional signal timing plans were ineffective in managing the rapidly changing traffic demands, leading to increased stop delays, travel times, and fuel consumption.
About The Customer
The Colorado Department of Transportation (CDOT) is responsible for managing and maintaining the state's transportation infrastructure, including highways, bridges, and traffic signals. CDOT aims to improve traffic flow, reduce congestion, and enhance safety for motorists. The department decided to implement an adaptive signal control system to address the unpredictable traffic patterns on the US 50 corridor in Pueblo, CO. By leveraging real-time data, CDOT sought to optimize signal timing and improve overall traffic operations, ultimately benefiting commuters, recreational travelers, and the environment.
The Solution
CDOT chose McCain’s QuicTrac Adaptive Signal Control System to replace the traditional time-of-day signal timing plans. The adaptive system utilizes real-time traffic data to create signal timing plans on-the-fly, responding to the current traffic demand. This approach allows for more efficient traffic management, reducing stop delays and improving travel times. The system was deployed along the eight-mile US 50 corridor, which includes 10 signalized intersections. Corridor operations were evaluated pre and post-implementation using measures such as travel time, stop delay, speed, fuel consumption, and vehicle emissions. The adaptive system demonstrated significant improvements in traffic flow and reduced environmental impact.

Turning A Stadium Into A Smart Building
Honeywell created what it called the “intelligent system” for the National Stadium in Beijing, China, turning the venue for the opening and closing events at the 2008 Summer Olympics into a “smart building.” Designed by highly controversial artist Ai Weiwei, the “Bird’s Nest” remains one of the most impressive feats of stadium architecture in the world. The 250,000 square meter structure housed more than 100,000 athletes and spectators at a time. To accommodate such capacity, China turned to Honeywell’s EBI Integrated Building Management System to create an integrated “intelligent system” for improved building security, safety and energy efficiency.

Airport SCADA Systems Improve Service Levels
Modern airports are one of the busiest environments on Earth and rely on process automation equipment to ensure service operators achieve their KPIs. Increasingly airport SCADA systems are being used to control all aspects of the operation and associated facilities. This is because unplanned system downtime can cost dearly, both in terms of reduced revenues and the associated loss of customer satisfaction due to inevitable travel inconvenience and disruption.

Buoy Status Monitoring with LoRa
The Netherlands are well-known for their inland waterways, canals, sluices and of course port activities. The Dutch Ministry of Infrastructure indicates that there are thousands of buoys and fixed items in and near water environments that would profit from IoT monitoring. One of the problems with buoys for example, is that they get hit by ships and the anchor cable breaks. Without connectivity, it takes quite some time to find out that something has happened with that buoy. Not to mention the costs of renting a boat to go to the buoy to fix it. Another important issue, is that there is no real-time monitoring of the buoys at this moment. Only by physically visiting the object on the water, one gains insight in its status.
