Transportation Infrastructure Solution

Situational Analysis

Many cities face significant issues with outdated transportation infrastructure, which negatively impacts traffic efficiency and safety.

Traffic Signals:

Inefficient signal timing is a primary cause of congestion. For instance, a typical Tier-2 city experiences an additional 40 minutes of delay during peak hours due to suboptimal signal phasing.

Signage and Markings:

Worn-out and unclear traffic signs and road markings are a direct safety hazard. On one major road, aged signage contributed to 12 accidents in a single year, including 3 with injuries.

Surveillance Coverage:

Incomplete coverage by electronic police and surveillance cameras creates blind spots.

An estimated 15% of intersections in the aforementioned city lack proper monitoring, allowing traffic violations to go undetected.

Support Infrastructure:

Structural assets like traffic poles and gantries are aging. A recent inspection found that 8% of poles over 10 years old have structural damage, posing a public safety risk.

While mobile and integrated signal lights offer temporary relief, their lack of coordination with fixed infrastructure can lead to signal confusion. The deployment of "Safety Sentry" devices is often insufficient, limiting their effectiveness in event pre-emption.

Traffic Signal Lights

An intelligent traffic signal control system will be implemented. High-precision traffic flow detectors (video, microwave) will be installed at intersections to collect real-time data on vehicle volume, pedestrian flow, and vehicle types. The system will use big data analytics and AI algorithms to dynamically adjust signal timing.

During peak hours, green light times on main arteries will be extended. During off-peak hours, right-of-way will be distributed more evenly to reduce wait times. Special timing plans will be created for sensitive areas like schools and hospitals. Mobile and integrated signals will be coordinated with the central system via wireless communication to ensure signal consistency during road work or temporary closures.
Traffic Signage

All traffic signs will be designed and installed in strict accordance with the national Road Traffic Signs and Markings standard (GB 5768). Placement, height, and density will be optimized for visibility based on road class and traffic volume.

On expressways and arterial roads, sign density will be increased to provide advance notice of exits and lane changes. Complex intersections will feature multi-faced or three-dimensional signs to enhance legibility.
Electronic Police, Surveillance Poles, and Safety Sentries

The layout of surveillance equipment will be planned to achieve comprehensive, omnidirectional coverage, eliminating all monitoring blind spots. High-definition cameras with intelligent analysis capabilities will be used to improve the accuracy of violation detection (e.g., red-light running, speeding, wrong-way driving).

"Safety Sentry" devices will be deployed more densely in high-traffic areas and around key institutions to enable real-time detection and alerting for abnormal activities and public safety incidents.
Traffic Poles and Gantries

High-strength, corrosion-resistant materials will be used for all new poles and gantries. Their design will account for future needs, with sufficient load-bearing capacity and space reserved for additional equipment like surveillance cameras and communication devices.

The placement and aesthetics will be designed to complement the urban landscape. Aging or damaged structures will be systematically repaired or replaced.

Construction and Implementation

Construction Workflow

Preparation: Site surveys, creation of detailed construction plans, acquisition of permits, and coordination of traffic management plans.

Foundation Work: Construction of robust foundations for all equipment, ensuring proper waterproofing and anti-corrosion treatment.
Equipment Installation: Mounting and calibration of all devices according to technical specifications.
System Integration: Connection of all hardware to the intelligent traffic control system and comprehensive functional testing.
Final Acceptance: A thorough inspection by relevant authorities to verify installation quality and system performance before commissioning.

Quality Control

Material Procurement: Sourcing of all materials and equipment from reputable, certified suppliers.

Process Supervision: Strict adherence to construction standards at every stage, with quality checks after each completed process.

Third-Party Testing: Engagement of an independent agency to test and certify equipment performance and installation quality.

Safety Assurance

Site Safety: Secure work zones with clear warning signs, barriers, and dedicated safety personnel.
Traffic Diversion: Coordinated traffic management during construction, using temporary signage to guide vehicles and pedestrians safely. Work will be scheduled during off-peak hours where possible.
Worker Safety: Provision of all necessary personal protective equipment (PPE) and mandatory safety training for all construction personnel.

Operations and Maintenance (O&M)

O&M System

A professional O&M team with clearly defined responsibilities will be established. A detailed manual of O&M procedures will govern all work.

Remote Monitoring

An IoT-based system will provide real-time remote monitoring of all equipment status and performance from a central control room.

Preventive Maintenance

A schedule of regular inspections, cleaning, calibration, and maintenance will be implemented to extend equipment lifespan and ensure reliability.

Emergency Response

A robust emergency response mechanism with pre-defined action plans will ensure rapid dispatch of repair teams to minimize downtime in case of equipment failure or accidents.
