... 11 This section presents available information on the perspectives of truck carriers and shippers regarding their use of highway facilities to move goods. Understanding of commercial vehicle operations by planning agencies has often not moved in lockstep with the demands of the industry.

... 12 incorporating truck Analysis into the Highway capacity Manual • Fowkes et al. conducted a stated-preference survey of shippers, haulers, and third-party logistics operators to estimate the value of time reliability for long-haul shipments; the average shipping distance for those surveyed was 280 km (174 miles)

... truck carrier and Shipper Perspectives 13 Trade organizations were a good source to identify and connect with the correct person within a company for participation in these efforts. It was felt that this kind of approach would lend credibility to the survey as well as prepare respondents for receiving the phone call, making them less likely to hang up.
From page 14...
... 14 incorporating truck Analysis into the Highway capacity Manual inclusion included transportation of freight shipments across the Hudson River (the main focus of the study)
From page 15...
... truck carrier and Shipper Perspectives 15 three attributes were most important to shippers and carriers and what characteristics influence the three attributes. In particular, the survey probed respondents on how these characteristics relate to factors such as design and geometry, which are associated with road planning and other functions that utilize the HCM.

... 16 incorporating truck Analysis into the Highway capacity Manual of recruiting freight establishments to participate in studies, and a lack of interest or time on the part of individuals in private enterprise in participating in these studies. Recent efforts are beginning to show better response to these types of outreach, in particular due to the growing sense among establishments that public–private partnerships can help provide solutions that improve business performance.

... truck carrier and Shipper Perspectives 17 When asked to rank issues of importance to their shipping mode choice, almost all choices were ranked as "very important" or "somewhat important" by a majority of respondents. The top choices that were ranked highest as "very important" were on-time performance, delivery time frame, cost of shipment, and damage to goods/security.
From page 18...
... 18 incorporating truck Analysis into the Highway capacity Manual Section 6: Reliability Out of the three focus characteristics of cost, travel time, and reliability, the latter appears to be highly associated with road design and characteristics. The survey asked what characteristics would be attributable to a reliable route.
From page 19...
... truck carrier and Shipper Perspectives 19 When asked about the types of roads needing design/geometry guideline modifications to better serve trucks, findings show that overall the respondents believe that there is a high need for modifications on all road types. Two out of three respondents reported a need for modifications to urban and non-urban freeways and other highway types, interchanges, urban streets, and intersections.
From page 20...
... 20 incorporating truck Analysis into the Highway capacity Manual 3.4.2 Decisionmaking Variables Establishments evaluate several attributes when making freight decisions. In interviews conducted across our studies, respondents identified transportation costs, travel time and reliability as the top factors in making freight decisions.
From page 21...
... truck carrier and Shipper Perspectives 21 Highway versus Non-Highway Modes of Transportation Several factors influence modal decisions: • The shipping needs of the business translated as the nature of the goods being moved has a critical impact on the modal selection. For instance, bulk goods such as coal are almost always shipped on rail irrespective of freeway performance.
From page 22...
... 22 incorporating truck Analysis into the Highway capacity Manual Long-Term Contracts Retailers reported using a bidding process to determine the most efficient way to ship goods across the country. The carriers are made aware of the shipping strategy of the company and are expected to price their bids accordingly.
From page 23...
... truck carrier and Shipper Perspectives 23 of 3.83. Travel times along freeway segments and information about the location of bottlenecks with travel time through the obstructed area received similar ratings at 3.74 and 3.70, respectively.
From page 24...
... 24 incorporating truck Analysis into the Highway capacity Manual to be recruited over the phone for short surveys. These findings are in line with earlier studies on freight decisionmaking such as those performed by Danielis et al.
From page 25...
... truck carrier and Shipper Perspectives 25 The calculated values of time varied from as low as $5.00/hr for long-haul movers shipping bulk commodities such as coal to as high as $170/hr for short-haul moves transporting high-end consumer electronic goods. Equation 1 presents the binary route preference utility model fitted to the New York/New Jersey panel survey.
From page 26...
... 26 incorporating truck Analysis into the Highway capacity Manual MR = dual value variable, = -0.275 if shipment is expected to be on-time with between 85% and 90% probability, = 0 otherwise; AG = shipping cost parameter for good type "g" values as shown in Exhibit 5; SC = shipment cost ($) (note: average shipment size in survey was 2,000 lbs)
From page 27...
... Truck Carrier and Shipper Perspectives 27 the probabilities of each route being selected based on measurable characteristics such as transportation costs, travel times, and reliability of the routes. • The negative coefficients on travel time in the model suggest that if a particular route has a higher travel time, then that route has a lower utility and is more likely not to be chosen for the shipment.
