"TDS system designs implement a variety of High Quality products."
Transport Data Systems uses a variety of products in its systems. TDS has worked closely with a number of companies to develop the specific drivers required to interface to these products. TDS has performed a significant amount of development testing with each of these products in a live traffic environment.
High Energy Pulsed Visible Illuminator
The TDS Visible LED illuminator provides pulsed flash illumination to enable photo capture during low light conditions. The illuminator strobe is digitally controlled with the illuminator only being activated during the exposure period. This results in a significantly lower duty cycle which results in a low average power consumption. The illuminator is capable of operating up to a duty cycle of 4 per cent with a maximum pulse width of 1.5 milliseconds. It will provide an operational lifecycle of 10+ years.
The visible illuminator features 63 Luxeon Rebel series LEDs and is part of the next generation of LEDs that raises the industry standard for light output, thermal management, cost and ease of use. The Rebel LED offers the worlds best LED light output with 130 lumens of pure White light, outstripping the performance of other power LEDs and significantly lowering the cost per lumen. It has a color spectrum that resembles a warm incandescent lamp.
The LEDs in the visible illuminator are focused through lenses to provide increased range while also reducing unwanted, off axis light pollution. Connection to the illuminator is through a Binder 423 connector, which is a rugged, high-performance circular connectors with excellent EMI shielding and IP67 compliant. It is ideal for severe industrial and commercial applications.
High Energy Pulsed IR Illuminator
Infrared (IR) illuminators are typically used in situations where ambient IR illumination is either not present or not sufficient to produce properly exposed near IR images. In that case an external IR illuminator can provide an extra source of invisible infrared light. IR illumination is ideal for nighttime operation without attracting unwanted attention and for covert operations; it can be used for indoor and outdoor use.
The TDS Infrared illuminator features 63 IR emitters. They are high intensity diodes molded in a water clear plastic. These Infrared LEDs have peak emissions at a wavelength of 850 nm, are highly efficient and are ideal for CCDtds_2009_css cameras, infrared applied systems, and night vision applications. Connection to the TDS Infrared illuminator is also through a Binder 423 connector, which is a rugged, high-performance circular connectors with excellent EMI shielding and IP67 compliance. It is ideal for severe industrial and commercial applications.

This radar is able to measure range, speed and angle of multiple objects simultaneously. It provides a hardware (antenna) and software selectable field of view, true object separation capability in range and Doppler, unrestricted operation when stationary or when moving at any speed. It has a small size and there are three different housings available. Stand-alone or network operation is possible. The latest generation is extremely robust, operates under all weather conditions and in a temperature interval from -40°C to +85°C. The radar was designed to be a versatile platform sensor. A set of different antennae are available, allowing specific configurations to meet the desired field of view. The detection software can be configured to meet most requirements regarding minimum and maximum range, and minimum and maximum speed measurement time.
A single radar is capable of providing coverage on up to four contiguous lanes. In addition to that, the microwave sensor has many other advantages:
- Low installation cost without interference to traffic and without inroad components.
- Low maintenance cost.
- Long lifetime.

TDS designs for AVC systems routinely use a light curtain to provide profile data on the target as it passes through the profiling zone and to separate vehicles. TDS uses light curtains produced by STI. STI produces a standard range of curtains from 3 to 5 feet in height. STI has developed a custom 10 foot curtain for TDS with 3/4 inch spacing on the bottom 5 feet and 1.5 inch spacing on the top 5 feet. STI produces environmental enclosures for the curtain transmit and receive elements for operation in all weather conditions. The light curtains have a serial interface and a separate digitial output which indicates curtain penetration. The curtain processor may be purchased in a case or stand-alone for mounting in a separately provided user case.


TDS designs for AVC systems routinely use an overhead laser scanner to provide profile data on the target as it passes through the profiling zone and to separate vehicles. The Model LMS211 overhead scanner is produced by Sick, Inc of Germany. It has been designed to operate externally in all weather conditions. It provides a serial output to the user. It requires a separate regulated power supply for operation of the unit and for powering the environmental control system built into the unit. TDS is an authorized distributor for the Sick transportation product line. TDS can provide the interface application for interfacing to the scanner from either a Windows or Linux application.


When required, TDS designs for AVC systems use a weigh-in-motion sensor to provide weight and axle data on the target as it passes through the profiling zone. Kistler quartz sensors allow wheel loads to be determined as vehicles drive past. These sensors are modular elements that are assembled into strips and installed into slots that are saw-cut across an asphalt or concrete road. The output from these sensors when coupled with the velocity data from the AVC Doppler radar produce accurate vehicle weights on a tire by tire basis.
TDS has developed a quartz sensor frame and carrier to allow for quick replacement of the quartz sensor with simple tools. No concrete work or on site potting required. Just remove the old carrier and replace it with a new one.
