Weigh-In-Motion
from SEA – Innovations and Efficiency
“Why use WIM systems in the first place?” The answer is simple: “Only a WIM system will provide detailed vehicle weight information!”
The worldwide increase in road usage is confronting governments, road owners and operators with the challenges of monitoring traffic and maintaining highways. Weigh In Motion (WIM) technology is the solution of choice for traffic monitoring, weight enforcement and weight-based tolling. A well-established WIM system is the key to sustainably managing and protecting the road infrastructure.

WIM system components
SEA WIM is a modular system consisting of hardware and software, as well as a communications infrastructure that connects measuring sites and system data center (back-office).
WIM site equipment
Basic configuration includes WIM sensors, inductive loop detectors and roadside cabinet with WIM electronics (controllers, UPS, protection systems).
Additional equipment and constructions of WIM measuring sites:
CCTV cameras
Overview cameras
ANPR cameras
Laser scanners for a vehicle dimensioning system
Gantry construction
Anti-vandal protective for the roadside cabinet
__________
Virtual Weigh Stations feature the iSINC WIM Electronics, Quartz Sensors, License Plate Readers and Side View Cameras.
WIM data center equipment
Back-office of a Weight-in-Motion system provides fully automatic processing, collection and archiving of data for at least 50 (fifty) dynamic weighing sites for 10 (ten) or more calendar years with a traffic intensity of 50,000 vehicles per day in one direction.
Server cabinet
Ethernet switch
Primary server
Backup server
Database repository
Firewall
Network video recorder
3 kVA uninterruptible power supply
NTP time servers
Administrator and dispatcher workplaces
WIM software
Multi-server system collects vehicle records on a central database server from any number of WIM sites and allows authorized users to connect to the server via the Internet and use a web browser to view records of any WIM measuring site.
Data processing in the WIM dynamic weighing system is provided by the following software modules:
Built-in controller software for local data collection and transmission
Back office server software with a database
Web portal software
Android app
WIM web-interface
Administrators, dispatchers and inspectors of the Weight-in-Motion system can access its data on their workstations (AWS) using a browser and personal log-in information. System provides the ability to define different levels of access for users in accordance with their functional authority.
SEA has developed a mobile web-interface for inspectors.
The web interface of the inspector allows you to:
View, verify and filter data in real time and in the archive (previously obtained from WIM measuring platforms)
Search for records with vehicle measurement data by various parameters, e.g. by date and time, WIM locations, license plate of the vehicle that committed the violation, etc.
View and print reports generated by the WIM back office system
The dynamic weighing system displays the following vehicle parameters to inspectors:
WIM site ID;
lane number;
vehicle registration plate that was recognized by the ANPR system, or its visible elements;
date and time of travel through the site;
movement speed;
type of vehicle in accordance with the classification;
number of axles and the distance between them;
loads on each axle and group of axles;
vehicle dimensions;
types of wheels (single / gable);
gross mass of the vehicle (road train);
excess gross mass;
excessive load on an axis / group of axles;
air temperature;
a photograph of the entire vehicle in a lateral projection with the ability to determine the number of axles.

High Speed Weigh-in-Motion Pilot System in Ukraine for direct enforcement
is a project for the design, supply and installation of 20 lanes of WIM monitoring systems that will be deployed at six sites covering arterial roads around the country’s capital, Kyiv. The system’s accuracy is in accordance to COAST A(5). The project also covers the set up of a back-office system, in addition to related civil works and communication infrastructure.
SEA is part of a three-member consortium that will build the Ukraine’s first commercial vehicle enforcement system:
Canadian highway traffic management technology company International Road Dynamics (IRD);
SEA, a supplier and manufacturer of electrical equipment, including traffic control systems;
Automagistral-Pivden LLC, one of the country’s leading road construction companies.
The turnkey project was awarded by The State Agency of Automobile Roads of Ukraine (Ukravtodor).
The main objective of the project is to implement a modular system comprised of software, hardware and communication infrastructure for Ukravtodor. The WIM back-office system collecting real-time traffic data and will support the enforcement of overweight and over-dimension commercial vehicles, as well as vehicles that may be in violation of local operating regulations. The data and analytics provided by IRD’s high-speed enforcement systems will also be used for more substantiated and streamlined planning of maintenance and repair of Kiev’s arterial road network.
Complementary technologies for the WIM systems is a vehicle dimensioning systems and off-scale detection. This will provide real-time information on a vehicle’s length, width, and height, as well as lane position in addition to axle load and gross vehicle weights. Designed for use in harsh weather and environments, WIM equipment will be able to cope with Ukraine’s often extreme climatic conditions.
Implemented by SEA and partners the Weigh In Motion System helps to detect and identify overloaded cars in real time - with guaranteed accuracy.
“We are extremely pleased and honored to have received this contract,” commented Randy Hanson, IRD’s president and chief executive officer. “We look forward to working together with our joint venture partners in delivering Ukraine’s very first integrated network of weigh-in-motion systems providing Ukravtodor with our world class, innovative and effective screening solutions to improve the overall efficiency and safety of its highway network.”
