Lane history and DAT trends help explain how freight markets change across individual transportation routes and over longer periods.
A lane generally refers to a recurring origin-and-destination route, such as freight moving between two cities, regions, or distribution centers. Studying historical lane data makes it easier to understand how rates, shipment volumes, equipment availability, and seasonal patterns have changed over time.
DAT is a widely used source of freight-market information, with data covering truckload activity, rates, capacity indicators, and other market measures. DAT Trendlines provides views of national and market-level freight conditions, while historical datasets can help users compare current conditions with earlier periods. In September 2026, DAT introduced an updated Trendlines format with selectable time periods, equipment categories, market maps, and load-to-truck ratio information.
Lane history is useful because national averages do not always describe what is happening on a particular route. A national rate can move in one direction while a specific regional lane behaves differently because of local demand, equipment availability, seasonality, weather, industrial activity, or changes in freight flows.
What lane history means
Lane history is a record of freight-market conditions associated with a particular route over time. Depending on the dataset, it may include average rates, shipment counts, equipment type, origin and destination markets, and capacity indicators.
For example, a historical lane record may help show whether a dry-van route normally experiences stronger activity during certain months. Comparing several years can also help separate recurring seasonal movements from unusual market changes.
What DAT trends measure
DAT trends can include several measures that describe truckload conditions:
- Spot rates represent prices associated with shipments arranged in the spot market.
- Contract rates represent negotiated transportation rates used for recurring freight movements.
- Load volume indicates the amount of freight activity represented by a particular dataset.
- Load-to-truck ratio compares available loads with available trucks and can provide context about market balance.
- Equipment categories commonly include van, refrigerated, and flatbed freight.
These measures should be considered together because one indicator rarely explains an entire freight market.
Importance
Why historical lane data matters
Historical information provides context for interpreting current freight conditions. A rate that appears unusually high or low may look different when compared with the same lane during previous years or similar seasonal periods.
Lane history can also help distinguish temporary disruptions from broader market movements. Weather events, holidays, agricultural cycles, retail activity, manufacturing changes, and shifts in available trucking capacity can all affect individual routes.
DAT reported that contract and spot market conditions changed considerably during 2026. In June, national dry-van spot rates exceeded contract rates for the first time since early 2022, while freight volumes were relatively stable compared with the previous year.
Who uses freight-market information
Different groups can use lane history for different purposes. Shippers can examine historical patterns when planning transportation budgets and freight schedules. Carriers can study route conditions when evaluating where freight activity has historically been concentrated. Analysts and researchers can use the information to understand relationships between freight demand, capacity, and rates.
Historical data is also useful for people who are new to freight markets. Rather than interpreting a single daily or weekly number, readers can examine longer periods and identify recurring patterns.
Key indicators to compare
| Indicator | What it shows | Why it matters |
|---|---|---|
| Lane rate | Typical rate associated with a route | Shows pricing movement over time |
| Load volume | Freight activity | Helps identify demand changes |
| Truck availability | Available transportation capacity | Provides supply context |
| Load-to-truck ratio | Relationship between loads and trucks | Indicates market balance |
| Seasonality | Recurring annual patterns | Helps explain predictable changes |
| Equipment type | Van, reefer, or flatbed activity | Shows differences between freight categories |
Recent Updates
Freight conditions during 2024–2026
Freight markets have moved through several different phases during the 2024–2026 period. DAT reported in late 2024 that new contract rates had begun moving higher after an extended period in which replacement contract rates were generally lower.
During 2025, the market continued to experience an extended period of relatively soft truckload conditions. DAT's 2026 outlook described a gradual transition rather than an immediate change in market conditions.
The pattern became more noticeable during 2026. DAT reported higher truckload rates during the spring as available capacity tightened. In March, higher fuel-related adjustments contributed significantly to rising national truckload rates.
By the middle of 2026, rate increases were occurring even when freight volumes were not rising at the same pace. DAT reported that June spot-rate growth substantially exceeded volume growth across major equipment categories.
Changing patterns later in 2026
Conditions shifted again during August. DAT reported that national average spot rates declined across van, reefer, and flatbed equipment, with August showing unusually large month-to-month decreases. Dry-van and refrigerated spot rates also moved back below contract rates after exceeding them during June and July.
Cass Information Systems reported a related pattern in its 2026 transportation indexes. Its July data showed shipment activity declining year over year while the Truckload Linehaul Index increased 8.6% year over year. This illustrates why freight analysis needs both volume and rate information rather than relying on one measurement.
More detailed DAT trend views
The updated DAT Trendlines format introduced in September 2026 gives readers more ways to examine historical and current freight information. Users can select weekly, monthly, or yearly views and examine different equipment categories. The updated format also includes market-level information for demand, capacity, rates, and load-to-truck ratios.
These changes reflect a broader trend toward more detailed freight-market analysis. Instead of relying only on national averages, users can examine regional conditions and compare multiple time periods.
Tools and Resources
DAT Trendlines
DAT Trendlines provides freight-market views covering national and market-level rate information. It includes van, reefer, flatbed, intermodal, and other transportation categories, with historical comparisons that can help users identify changes over time.
DAT historical rate data
Historical DAT information can be useful when studying lane movements across different periods. Comparing similar weeks, months, or seasons can provide context for changes in individual routes.
Cass Freight Index
The Cass Freight Index provides another perspective on transportation activity. Its shipment and expenditure indexes can be reviewed alongside the Truckload Linehaul Index to understand how freight volumes and rates are moving together or separately.
Simple lane-history worksheet
A basic spreadsheet can also help organize observations. Useful columns include origin, destination, equipment type, period, average rate, load volume, truck availability, and notes about unusual events.
Keeping these fields consistent makes it easier to compare one period with another and identify recurring seasonal patterns.
FAQs
What is lane history in freight transportation?
Lane history is a record of historical freight conditions for a particular origin-and-destination route. It can include rates, volumes, equipment categories, and capacity indicators.
How can DAT trends help explain lane history?
DAT trends provide market information that can be compared across weeks, months, and years. This helps show whether a lane movement is seasonal, temporary, or part of a broader freight-market change.
Why do freight rates change on individual lanes?
Rates can change because of demand, truck availability, seasonality, weather, fuel movements, industrial activity, holidays, and changes in freight flows. Local conditions can make an individual lane behave differently from the national market.
What is a load-to-truck ratio?
A load-to-truck ratio compares the number of posted loads with available trucks within a particular market or dataset. Changes in this ratio can provide context about the balance between freight demand and transportation capacity.
How should historical DAT data be interpreted?
Historical DAT data should be examined across comparable periods and alongside other indicators. A single weekly or monthly figure may not represent the longer-term direction of a lane.
Conclusion
Lane history and DAT trends provide useful context for understanding how freight routes change over time. Historical rates, shipment activity, equipment availability, and load-to-truck ratios can reveal patterns that are not visible from a single market figure. Developments during 2024–2026 show that freight conditions can change because of shifting capacity, seasonal activity, fuel movements, and regional market factors. Comparing multiple indicators and time periods provides a clearer picture of historical freight-market behavior.
