SEGMENT INFORMATION [Abstract]

SEGMENT INFORMATION

14.          SEGMENT INFORMATION

The Company's Chief Executive Officer and management regularly review financial information for the Company's discrete operating segments. Based on similarities in the economic characteristics, nature of products and services, production processes, type or class of customer served, method of distribution and regulatory environments, the operating segments have been aggregated for financial statement purposes and categorized into two reportable segments:  Intersection and Highway.    

Autoscope video is our machine-vision product line, and revenue consists of royalties (all of which are received from Econolite), as well as a portion of international product sales. Video products are normally sold in the Intersection segment. RTMS is our radar product line, and revenue consists of international and North American product sales. Radar products are normally sold in the Highway segment. All segment revenues are derived from external customers.   

Operating expenses and total assets are not allocated to the segments for internal reporting purposes. Due to the changes in how we manage our business, we may reevaluate our segment definitions in the future.   

The following tables set forth selected financial information for each of our reportable segments (in thousands): 

	For the year ended December 31, 2021
	Intersection		Highway		Total
Revenue	$	9,323	$	3,919	$	13,242
