关于客户
The City of Temecula is a rapidly growing urban area in California, USA, known for its residential communities, commercial districts, and proximity to the I-15 freeway. The city has been facing significant traffic congestion issues, particularly during peak hours, which has affected the quality of life for its residents. Temecula's major corridors are crucial for connecting residential areas to commercial zones and institutions, making efficient traffic management a priority for the city administration. The city has been proactive in seeking advanced traffic solutions to improve mobility, reduce commute times, and enhance the overall quality of life for its residents. With a focus on leveraging technology to address these challenges, Temecula has implemented various initiatives to optimize traffic flow and reduce congestion.
挑战
Hefty Commute Times and Congestion Plagued the City’s Primary Arterials and Freeway Interchanges. Temecula’s major corridors connect the City’s residential communities to commercial districts, institutions, and the region’s primary interstate, the I-15 freeway. Existing signal coordination did not respond to prevailing traffic conditions causing unnecessary congestion. In addition, the lack of communication with I-15 signal interchanges caused traffic to backup on the off-ramps, causing residual queuing during the morning and evening rush hours. The project scope included seven major arterials spanning 18 miles of roadway, connecting residential communities, commercial districts, and the freeway. The city faced significant congestion levels, traffic backup on off-ramps, and major intersections that included freeway access.
解决方案
McCain’s QuicTrac adaptive control software was implemented to lower congestion and maximize thoroughfare with a system that is easy to understand, and simple to set up and maintain. It was selected for its proven local success and ability to maximize the use of Temecula’s existing infrastructure - detectors, controllers, and central control software. Each arterial was evaluated for current conditions highlighting necessary infrastructure improvements (i.e., separating loop detectors to provide lane-by-lane vehicular data) and signal timing plan updates. New traffic volume counts were collected and analyzed to engineer new coordination plans that served as the base parameters for adaptive operations. At the major freeway access points, yellow yield or one-way communication with Caltrans’ signals was established. Coordination plans were then implemented to clear traffic from the ramp signals onto the main corridors to minimize queuing down the ramps, whereas normal coordination emphasizes only movement along the corridor.

Case Study
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.

Case Study
Smart Street Light Network (Copenhagen)
Key stakeholders are taking a comprehensive approach to rethinking smart city innovation. City leaders have collaborated through partnerships involving government, research institutions and solution providers. The Copenhagen Solutions Lab is one of the leading organizations at the forefront of this movement. By bringing together manufacturers with municipal buyers, the Copenhagen Solutions Lab has catalyzed the development and deployment of next-generation smart city innovations. Copenhagen is leveraging this unique approach to accelerate the implementation of smart city solutions. One of the primary focus areas is LED street lighting.
Case Study
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.
Case Study
China Mobile Smart Parking
Smart Parking, powered by NB-IoT technology, is making it easier for drivers to find free parking spots. Cities can better manage their parking assets and maximize the revenue available to them as a result. Drivers searching for parking create congestion and pollution by circling and hunting for available parking. Smart Parking services are able to significantly ease these problems by guiding a driver directly to a parking space.
Case Study
Barcelona Case Study
Barcelona’s heavy traffic and its associated high levels of pollution were the primary factors that motivated some companies and universities to work on strategies for improving traffic in the city centre. Bitcarrier is one of the technologies involved in the In4Mo Project, whose main objective is to develop the applications that form the core of smart mobility, one of the fundamental pillars of the smart city concept.
