A new method for managing signal-controlled intersections
Introduction
Everyone likes to catch the green light. Nobody likes to sit in traffic jams. However, beyond the general frustration of endless waiting, transportation inefficiencies can seriously disadvantage a city or country's economy and environment. According to INRIX's 2019 Global Traffic Scorecard, the American Transportation Research Institute estimates that the total cost of traffic congestion in the freight sector is as high as $74.1 billion annually. But it's not just the economy that's affected. Petroleum consumption, CO2 emissions, and climate change caused by traffic congestion take a toll on our planet. Now, by leveraging new technology, intelligent
traffic management smooths and optimizes vehicle flow, getting people and things to where they're going quicker than ever before.
Our customer, a research institute of environmental engineering in a European university, was tasked with this challenge when their city's Urban Congestion Commission called for improved traffic signal control to reduce congestion and travel time. The research institute developed its own algorithm and created a new method for managing signal-controlled intersections by adopting machine learning. Their strategy uses radar to detect and then predict the behavior of traffic. With the integration of machine learning, optimized traffic and control light timings reduce red lights when there is no oncoming traffic. An embedded PC solution was required
for this application to process data and connect to the peripherals.
Customer's Requirements
Small yet Powerful
The embedded PC connects to the radar, collects traffic data, processes the data, then transmits it to the central control room. To meet the roadside edge computing system’s requirements, the embedded PC must have high-performance computing power in a small form factor to permit installation in the small roadside cabinet.
Multiple LAN and I/O Connection
The embedded PC must connect to the traffic management center. A network connection facilitates this communication, with the control room analyzing the incoming data, and the embedded PC commanding and controlling the traffic lights. Therefore, LAN, I/O connections, and expansion are necessary.
Outdoor Conditions
A traffic system is a harsh installation environment. The embedded PC must adapt to accommodate varying outdoor application environments, including shock, vibration, and wide temperature ranges, to ensure uninterrupted traffic service.
Why Cincoze?
High Performance for the Edge DI-1000 is a high-performance embedded PC supporting Intel® Core™ mobile processors
from Core™ i3-6100U up to the Core™ i7-6600U, and measuring only 203 x 142 x 66.8 mm.
The high performance plus small footprint makes the DI-1000 perfect for machine vision, in-vehicle, and mobile surveillance applications.
Multiple Expansion Options
DI-1000 includes various I/O connections, including DVI-I, DisplayPort, 2x LAN, 6x COM, 6x USB, 8x isolated optical DIO, and remote power on/off switch. The unique Cincoze CMI and CFM technologies allow DI-1000 expansion and upgrades with more I/O like LAN, PoE, M12 connections, and ignition sensing. These expansion modules provide ease of maintenance while saving costs.
Ruggedness
DI-1000 inherits its rugged DNA from the Cincoze DIAMOND series. It is fanless and cableless, operates in temperatures from -40 to 70℃, supports wide range DC input from 9 to 48 VDC , has a high tolerance for shock and vibration, has a high standard electric protection, and uses a SuperCAP as a maintenance-free CMOS battery. Improved traffic control has successfully reduced traffic congestion and traveling time. The DI-1000 has currently helped the traffic signal system deliver a 60% reduction in traffic queues
during rush hours.
