Transportation infrastructure is the lifeline of the nation. An efficient and safe road network allows goods to reach the markets quickly, thus, stimulating economic activity and ensuring trade competitiveness. According to the Highway Statistics, in the United States, over 46,000 miles of interstate roads, combined with a network of almost 4 million miles of other roads, makes up the nations lifeline. Each year, nearly five trillion dollars worth of goods is transported via the nations lifeline via commercial trucks. Unfortunately, commercial truck traffic also contributes greatly to the cost of deteriorating highways across the nation. The increased costs of maintenance, combined with the diminished highway funds available, have meant that many roads are now in or rapidly approaching a critical condition. Industry experts estimate that there is currently a $300+ billion shortfall to repair roads and bridges to an acceptable standard. For many years, states have been looking at developing a system that can be beneficial to the trucking industry, taxpayers, and the states, while helping to protect the infrastructure. It is the Weigh-In-Motion (WIM) technology which provides benefits to all parties involved. In this project, several piezoelectric sensors, fiber optical sensors, and an innovative microwave sensor were evaluated. The field-test site is located in a weigh station operated by Department of Public Safety (DPS) at a north-bound area of interstate highway I-45 about 60 miles north of Houston, Texas.
