Vehicle data from connected cars provide dozens of streaming data attributes such as odometer data, location data, speed, ignition status, and more. These limitations make it difficult for traffic engineers and municipalities to determine accurate traffic patterns, and hinder efficient infrastructure planning, understanding of population changes and migration, and fuel tax projections.Ĭonnected Vehicle Data: A Better Way to VMTĬonnected vehicles provide a better way to capture real-time traffic data for VMT. Delayed data collection: Data processing and publishing can take up to 3 months from the time of the initial traffic data collection.Uncontextualized data: Traffic counters can not determine origin and destination information or in-vehicle parameters.Underrepresentation of data: Roads are often underrepresented in rural areas or dense urban areas.Inaccurate data collection: VMT is often based on average annual daily traffic (AADT), which does not account for real-time traffic changes.Incomplete data collection: Traffic counters appear on a small sample of roads and do not provide a complete understanding of traffic and VMT.Of the other half, most (76%) believed that their estimates were within 20 percent of the actual value.” In fact, according to the US Federal Highway Administration, “about half of US States indicated that they had no idea or way to determine how accurate their estimates were. Some states sample as few as 10% of roads, and others make counts on a cycle of up to 9 years. Practices used to identify VMT vary significantly by state and are often not thoroughly documented. In the USA, there are only 5,000 traffic counting locations nationwide. The traffic count is multiplied by the distance measured to determine how many miles each vehicle has traveled. Traffic counters are usually electric sensors placed in specific locations on the roads to count how many vehicles pass the sensors at each point. Vehicle miles traveled is usually calculated based on measurements made by traffic counters on public roadways. It is calculated as the sum of the total miles traveled by each vehicle. Vehicle miles traveled is a measurement of the total distance traveled by all vehicles in a given area over a given period of time. Vehicle telematics data from connected cars can offer a better solution. However it should be noted that current methods of obtaining VMT data are often inaccurate. Setting a tax on VMT is quickly becoming a popular alternative. The adoption of electric vehicles and autonomous vehicles has prompted many governments to rethink their tax policies. It has become evident that taxes and infrastructure planning will be heavily dependent on this metric. As a result, vehicle miles traveled data is becoming an important topic in policy-making. The rise of fuel efficient vehicles, hybrid and fully electric vehicles is changing that paradigm. Historically, highway infrastructure has been funded by fuel taxes. Studying VMT (also known as vehicle kilometers traveled outside of America) can lead to insights in changing behavior, such as the shift in traffic trends from COVID-19, it can provide vital information regarding traffic management for smart cities, help businesses make smarter choices for infrastructure development and retail planning, and much more. Vehicle miles traveled (VMT) is a key metric in decision making for many governments and businesses.
