Introduction A large statewide survey of truck traffic origination, destination, and freight characteristics provided the data for in-depth county level reports of freight truck movement in Washington State. Considerable detail on road usage, truck weight, truck configuration, commodity type, and seasonal traffic variation is available in this survey. We were able to examine a rich set of characteristics for trucks whose freight was either destined for or originating from a particular county. It is important to not the survey does not capture truck movement that did not pass through one of 20 survey sites located on major routes throughout the state (see Table 1A for survey sites). For this reason, considerable intra- and intercounty traffic will not be included for some counties depending on their proximity to a survey site. Again, these truck characteristics reflect only the truck movements as reported at the statewide survey locations.

This study was the first in the United States to collect statewide freight truck origination and destination data through direct interviews of truck drivers at weigh stations. Over 300 persons conducted these personal interviews of a total of 30,000 truck drivers, providing an extensive database on freight and goods movements in Washington State. 1
Method of Analysis Truck traffic characteristics at the county level were analyzed for trucks whose trips either originated or ended in a particular county. Given the survey data, there was no feasible method for analyzing truck traffic that was simply passing through the county. Detailed truck traffic characteristics for each of Washington s 39 counties by season included number of trucks with freight destined for that county per day, their payload weight and commodity type; road usage, including number of trucks per day, freight weight and commodity type; and number of trucks per day, freight weight and commodity type by city of cargo origin and destination. Truck traffic was analyzed on an annual basis for the following characteristics: county road usage, average and total truck tonnage, and number of trucks by commodity; distribution of freight weight by commodity and by road; type of commodity hauled by truck configuration; and truck carriers home base for truck trips originating or ending in that county. Truck traffic data is likely to be more accurate in terms of relative differences by road, season, etc., than actual magnitude for any one characteristic due to the nature of the survey approach. 2
Presentation of Results Detailed truck traffic characteristics are presented for Washington s 39 counties in a set of nine tables for each county. Table 1 presents information by road for truck traffic either originating or ending in that county for each season. Characteristics include total number of trucks, number of trucks with freight, average payload, and total tonnage. In addition, the percentage of loads by commodity on each road is calculated. Tables 2 and 3 present seasonal truck traffic characteristics by city of cargo origin and city of cargo destination, respectively. For each city, the daily number of trucks, trucks with freight, their average payload weight, and total truck traffic weight are presented. Again, there is a breakdown by commodity type for each city. Table 4 summarizes truck traffic characteristics for trucks whose trips end in that county by season. Total daily truck traffic, number of trucks with freight, average payload weight, and the total tonnage per day as well as the percentage of truckloads by commodity are presented. Table 5 analyzes truck traffic originating or ending in that county by commodity. The number of trucks per day as well as the average and total payload by commodity is presented. In addition, truck traffic usage by road is detailed for each commodity. Table 6 shows distribution of payload weight by commodity for truck traffic originating or ending in that county. Five weight categories in five-ton increments are used. Table 7 presents distribution of payload weight by road for truck traffic originating or ending in that county. Weight characteristics by commodity and by road are easily identified from these two tables. Table 8 shows truck configuration by commodity for truck traffic originating or ending in that county. The percentage of trucks with freight by configuration is presented for each commodity. Table 9 presents truckers home base by city and the number of Washington-based carriers for truck traffic originating or ending in the county. Overall, this county-by-county disaggregation of truck movements shows the powerful impact of particular commodity movements on certain roads and during certain seasons. Farm commodities are hauled from the field to the processor or market on a seasonal basis. Lumber harvest has considerable seasonal variation as well. Construction or closures on major roads used for these purposes will need to be planned accordingly. As different industries grow or shrink, they create specific demands on the transportation infrastructure that may need to be accommodated in future transportation planning. These results represent a summary of truck traffic origin and destination information at the county level. This information should be useful for state and county planning with respect to traffic sources, either origin or destination, and the characteristics of this traffic. It should also be valuable for planning road maintenance and construction at the county and regional level. 3
King County Results The most heavily used truck route in King County is Interstate 5 (I5), with daily average truck traffic ranging from 15,116 in summer to 11,358 in spring (Table 1). Interstate 90 (I90), Interstate 405 (I405), State Route 167 (SR167), and State Route 18 (SR18) are the next most heavily used truck routes, averaging between 2,000 and 5,000 trucks per day. Other routes averaging more than 200 trucks per day include State Routes 101, 522, 167, 99, and 520 (SR101, SR522, SR167, SR99, and SR520). The most commonly hauled products on I5, in order of magnitude, are food, general freight, lumber or wood products, paper or pulp products, and agricultural products, with an average payload weight ranging from 14 to 18 tons. Truck traffic on I90 is similar in composition, but more agricultural products and transportation equipment are hauled. In addition, no paper or pulp products are hauled on I90, according to the survey data. Average daily truck traffic on I90 is highest in fall, averaging 4,097 per day, and lowest in summer at 3,127 per day. The average payload weight is slightly higher for I90 than I5, ranging between 16 and 20 tons across the seasons. Truck traffic on I405 ranges from an average of 4,045 trucks per day in summer to 3,253 per day in fall. Cargo composition is similar to I5 and I90: food makes up one-fifth or more of the trucks with freight and other major categories include general freight, lumber or wood products, paper or pulp products, and agricultural products. Payload weights average between 14 and 18 tons. Daily truck traffic on SR167 averages from 2,768 trucks per day in fall to 3,782 per day in winter, with similar cargo characteristics to the previously mentioned routes. On SR18, daily truck traffic is much higher in winter, averaging 4,664 trucks per day. During the rest of the year, daily truck traffic is below 3,000 trucks per day. Cargo is again quite similar to the other routes. Average payload weights for all the main trucking routes in King County rarely exceed 20 tons; the highest average payload weight of 27 tons occurs on SR169 in summer, when twothirds of the loads are carrying lumber or wood products. Average payloads ranging between 30 to 31 tons occur on SR203 in fall, SR3 in winter, and SR203 in spring, but these routes have six or less loaded trucks per day. The majority of truck traffic originating from King County leaves from the town of Seattle, ranging from an average of 4,315 trucks per day in summer to 2,580 per day in spring (Table 2). Main categories of outgoing freight from Seattle include food, general freight, mail or packages, and petroleum, in declining order of importance. Kent and Auburn have the next highest levels of outgoing truck traffic. Kent averages from 1,425 trucks per day in winter to 1,195 per day in spring, while truck traffic from Auburn ranges from a daily average of 490 in winter to 325 in spring. Major categories of freight from Kent include general freight, food, and pulp or paper products. General freight, transportation equipment, food, and lumber or wood products make up the main categories of cargo from Auburn, with considerable seasonal variation. Freight from 15 other towns in King County is presented in Table 1; the same freight categories mentioned above are dominant in these towns as well. The highest average payload weights of 34 and 40 tons occur for freight originating from Black Diamond in fall and spring respectively, when freight consists of coal and machinery. Trucks headed to destinations in King County are most likely to be headed for Seattle, Kent and Auburn (Table 3). Seattle receives on average from a high of 4,620 trucks per day in winter to a low of 4,237 in fall; Kent receives from 1,906 per day in winter to 1,557 in summer; and Auburn receives from 695 trucks per day in winter to 406 in summer. Another 15 towns receive significant but lesser amounts of daily truck traffic (see Table 3). Freight to Seattle is most likely to fall into the categories of food, general freight, and agricultural products, although lumber or 4
wood products and pulp or paper products are also important. Freight to Kent consists mainly of food, general freight, and pulp or paper products, in order of importance. Food, agricultural products, general freight, lumber or wood, petroleum, and transportation equipment make up the main freight categories bound for Auburn. Average payload weights are 20 tons or less for truck traffic heading to most towns in King County. The highest average payload weight of 40 tons occurs for trucks heading to Burien in winter, when transportation equipment is the only category of freight in the survey. Total truck traffic heading for or leaving from King County ranges from 17,823 trucks per day in winter to 14,323 trucks per day in spring (Table 4). The most common freight categories include food products, which make up 20% or more of all trucks with freight; general freight; lumber or wood products; agricultural products; and pulp or paper products. Average payload weights are highest in summer at 18 tons. Table 5 shows road usage by type of freight for the major commodities hauled into or out of King County over the entire year. I5 is used by over 80% of all trucks hauling freight in King County. Other routes that are heavily used by trucks include SR167, used by 19% to 32% of loaded trucks across the seasons; I90, used by one-fourth of all loaded trucks, except those hauling pulp or paper; and I405, used by 15% to 32% of loaded trucks across the seasons. Food products are the predominant commodity hauled into and from King County, accounting for 21% of trucks with loads and 22% of total tonnage. Lumber or wood products make up 7% of loaded trucks and account for 9% of the total tonnage. The heaviest average payload weight among the most commonly hauled commodities is 21 tons, for lumber or wood products. Weight category by commodity for trucks hauling freight into or out of King County is presented in Table 6. For trucks carrying food products, half have loads weighing between 15 and 25 tons. For trucks carrying general freight, nearly three-quarters have payload weights of less than 30 tons. For trucks carrying lumber or wood products, two-thirds have payload weights of 20 tons or more and 21% weigh over 30 tons. Ten percent or less of the loads in other freight categories fall in the over 30-ton category. Table 7 shows weight category by roadway for truckloads originating or ending in King County. For the 27,596 trucks with loads in the survey using I5, one-fourth have payload weights of less than five tons while 23% have payloads in the 20- to 25-ton category. I90 carries the highest percentage of trucks with freight weighing 20 tons or more; half of all loads on I90 fall in this category. Just 13% of the trucks with loads on I90 fall in the under 5-ton category. For the rest of the major truck routes in King County, 21% to 29% of the loads weigh less than 5 tons. The most common truck configuration for trucks carrying loads into or out of King County is the tractor-trailer configuration, accounting for half of the trucks with loads (Table 8). Another 17% each are straight trucks and tractors with two trailers. Sixteen percent are truck and tractor configurations. Food products are mainly carried by tractor and trailer configurations (60% of loads). For the trucks carrying lumber or wood products, 45% are tractor and trailers and 23% are tractors plus two trailers. Half of all general freight is hauled by tractors plus two trailers, and another 32% is carried by tractors and one trailer. Over a four-day period (one day in each season), a total of 50,779 trucks, loaded and empty, were either heading for or leaving King County (Table 9). Of these trucks, 64% were Washington-based carriers. Seattle is home base for 18% of the surveyed carriers, while another7% each are based out of Kent, Tacoma, and Portland, Oregon. 5
