76 7.1 Introduction The primary focus of this research project has been to develop a method (or tool) that public- and private-sector decision makers can use to identify, categorize, and evaluate quickly implementable, low-cost capital, operational, and pub- lic policy actions that can enhance freight mobility by address- ing persistent system constraints. The tool is applied to develop a catalog of low-cost actions or classes of actions that can be quickly implemented to address the nation’s freight-system mobility constraints, especially along corridors or at locations that impact freight mobility at a national level. The approach in developing the catalog of strategies recog- nizes the inherent conflict or disconnect between the criteria of quickly implementable low-cost improvements and large cap- ital investments required to expand the capacity of the freight transportation system, especially for projects of national signif- icance. In other words, addressing freight mobility constraints at locations that may impact freight mobility at national levels would require large capital investments that encompass low-cost physical improvements. Low-cost improvements are effective in eliminating and/or reducing the congestion at these locations. With this recognition, the theme in developing the catalog of actions is to identify proven low-cost improve- ments that have the potential to enhance freight mobility to noticeable extents even though such actions may not by them- selves necessarily remove the constraint entirely. Depending on the mode of freight transportation, the low- cost improvements could be more operations, regulatory, pol- icy, or technology oriented and less physical. While low-cost improvements for the highway mode may include all types of actions (i.e., physical, operational, and regulatory), those for rail and ports may not include physical actions. For physical low-cost improvements, site and traffic characteristics and other factors contributing to a constraint at a given location may not necessarily be identical to other locations. Therefore, improvement strategies presented in the catalog are generic; however, implementation at a particular location would require consideration of specific site characteristics and operational practices. Similarly, given the uniqueness of each deepwater port, an effective action at one port may not necessarily be effective at another port. 7.2 Approach to Developing Catalog of Strategies In discussing options to address the capacity issues on the freight transportation system, greater understanding is needed of what drives private- and public-sector decision makers to want change, to be willing to pay for it, and to work together to maximize the return on investment in terms of meeting their goals, both quantitative and qualitative. Given the disparities of how each sector defines and measures success, it is impor- tant to consider shared, cooperative project implementation to reconcile any conflicts between these values (i.e., public versus private, national versus local, and high-cost versus low-cost improvements), focusing on projects that use relatively low- cost operational strategies or technology innovations to address capacity and mobility constraints. Recognizing that the characteristics of each mode in terms of the level of public- and private-sector involvement and part- nership in decisions regarding funding improvement projects determine the approaches to addressing freight mobility, dif- ferent approaches are used in developing the catalog of strate- gies. The catalog of improvements are developed from case studies that represent projects that have been implemented in different parts of the country and to address a variety of freight mobility constraints. The improvements target locations or corridors where major constraints within each modal freight transportation network occur. Addressing these constraints is expected to improve freight mobility significantly at a national level. The following subsections discuss the locations of major freight mobility constraints and present a catalog of low-cost improvements to address specific constraints for each mode.

77 7.2.1 Highways Locations of nationally recognized bottlenecks in the high- way freight transportation system present opportunities for implementing low-cost improvements to help alleviate the constraints. The freight bottlenecks study (12) identified the top 30 freight highway bottlenecks to be poorly functioning interchanges on the NHS. These bottlenecks were identified based on analysis of the performance in terms of volume/ capacity ratios and delay derived from freight flow data. The study has shown that more than 70 percent of bottlenecks occur on the interstate highway system and 42 percent were interchange related. These top 30 bottlenecks occur at urban interchanges in metropolitan areas with high population den- sities and major freight activity centers. The study also con- cluded that low-cost improvements can result in significant improvements in traffic flow. Analysis of freight performance measurement data (88) re-ordered the top 30 freight bottle- necks. This latter analysis was based on truck traffic volume and reductions in truck speed below the posted speed limits through these interchanges. Table 30 shows the locations of the top 30 bottlenecks and their traffic and other performance CSI ranking (2002) ATRI ranking (2009) Location State Freight Congestion value AADT (2007) V/C (2002) AADT (2002) Truck % (2002) 5 1 I-80 @ I-94 Interchange IL 2,722,629 144,602 1.104 128,049 24.0% 19 2 I-95 @ SR-4 Interchange DE 1,435,661 93,979 0.923 88,425 15.5% 9 3 I-90 @ I-94 Interchange IL 921,688 175,548 1.151 163,805 6.0% 3 4 I-285 @ I-85 Interchange (“Spaghetti Junction”) GA 899,899 286,300 1.850 254,600 16.0% 13 5 I-95 @SR-9A (Western Hwy) NY 656,190 98,834 1.187 79,755 5.0% 10 6 I-40 @ I-65 Interchange (east) TN 446,933 192,073 1.925 114,280 17.1% 6 7 SR-60 @ SR-57 Interchange CA 426,569 344,294 1.173 216,000 12.0% 24 8 I-10 @ I-15 Interchange CA 382,200 289,504 1.190 258,000 12.0% 21 9 I-45 @ US 59 Interchange TX 318,853 265,768 2.065 212,241 7.0% 26 10 I-45 @ I-610 Interchange TX 259,704 301,828 2.396 260,770 8.1% 4 11 I-20 @ I-75/I-85 Interchange GA 234,258 452,556 1.500 199,000 16.1% 2 12 I-17 (Black Canyon Fwy): I-10 Interchange (the Stack) AZ 225,892 309,032 0.985 255,371 9.1% 25 13 I-95/I-495 MD 183,772 260,904 1.912 185,125 7.1% 1 14 I-710 @I-105 Interchange CA 156,987 280,731 1.393 224,000 9.0% 14 15 I-71 @ I-70 Interchange OH 144,772 188,724 1.648 107,722 17.0% 7 16 I-80 @ I-580/I-880 in Oakland CA 144,009 292,437 2.241 177,763 9.0% 12 17 I-75 @ I-85 Interchange GA 138,824 353,005 1.018 295,000 16.0% 15 18 I-880 @ I-238 CA 129,421 339,634 1.206 271,000 10.8% 18 19 I-695/I-70 and I-95 exit 11 MD 119,629 217,885 1.983 165,050 7.0% 20 20 I-10 @ I-110/US 54 Interchange TX 115,516 232,273 1.379 200,677 7.8% 30 21 I-25 @ I-76 Interchange CO 107,116 246,429 1.198 237,839 9.0% 27 22 I-10 @ I-410 Loop North Interchange TX 93,066 193,670 1.747 117,179 7.8% 17 23 I-285 @ I-75 Interchange GA 58,784 211,107 2.108 153,600 16.1% 11 24 I-290 @ I-355 Interchange IL 56,591 239,337 1.782 213,906 9.0% 23 25 I-10 @ SR-51/SR-202 Interchange (Mini-Stack) AZ 51,486 339,804 1.955 152,880 7.0% 28 26 I-110 @ I-105 Interchange CA 40,647 365,953 1.484 230,000 6.0% 16 27 SR-91 @ SR-55 Interchange CA 36,746 315,719 1.103 298,000 8.1% 29 28 I-95 @ SR-595 Interchange FL 28,291 315,890 1.395 288,000 9.0% 8 29 I-405 (San Diego Fwy) @ I-605 Interchange CA 16,732 472,480 1.376 377,000 6.0% 22 30 SR-134 @ SR-2 Interchange CA 3,200 235,433 1.083 205,000 6.2% Note: Freight Congestion value = number of trucks multiplied by difference between average and speed limits Table 30.

characteristics (also shown in Figure 3). The traffic data and congestion measures (indicated by volume/capacity ratios) for these locations were derived from FAF2 traffic analysis data (58). The values shown in Table 30 represent maximum v/c ratios and corresponding AADT and percentage of trucks in the fleet for the critical leg of each interchange. Table 30 also shows the AADT for 2007 derived from the FAF provisional estimates. The challenge in developing a catalog of low-cost physical improvements is the lack of specific site (geometric) data at these locations. However, as noted previously, the func- tional highway classes (i.e., urban interstates) where these top 30 bottlenecks and the locations (i.e., interchanges or ramps) where the constraints typically occur are known. Based on the knowledge of the location of the constraints, the methodology was applied to identify the range of constraints and then identify the applicable low-cost improvements for each constraint. Table 31 presents the catalog of improvements to address freight mobility constraints encountered on the highway sys- tem. For each constraint, a single improvement or a combina- tion of improvements can be implemented depending on the severity of the constraint or the physical conditions on site or both. Note that these improvements are generic in the sense that they are not designed to any specific site condition or loca- tion. This catalog is intended to serve as a guide and does not include any design details or specifications for implementation. 7.2.2 Railroads Within the context of improving freight movement by rail, the most urgent policy need does not appear to be investing in expensive projects like double-tracking mainline rail freight corridors, expediting port access, and building new port ter- minal capacity, but rather smart investments to address per- sistent operational and site-specific weaknesses in the freight transportation network. In developing a catalog of low-cost improvements, the first step is to identify locations or corri- dors within the rail freight transportation system where major bottlenecks occur whereby alleviating congestion at these locations would improve rail freight movement at the national levels. For example, in 2007, the Alameda Corridor East and 78 Constraint Constraint Description Improvements Ph ys ic al C on st ra in ts Weaving Where traffic must merge across one or more lanes to access entry or exit ramps.

80 the double-tracking of Union Pacific’s Sunset Route from El Paso to Colton, California, were recognized as projects of national significance by virtue of their location within the rail network and their contribution to rail freight movement (90). Also, the Chicago Region Environmental and Transportation Efficiency (CREATE) program assembles a number of proj- ects of importance to multiple railroads, Metra, and Amtrak in the Chicago area with the stated goals of not only reducing rail and motorist congestion, but also improving passenger rail service, enhancing public safety, promoting economic development, creating jobs, and improving air quality (29). For railroads, deepwater ports, and inland waterways, the catalog of low-cost improvements that can be quickly imple- mentable is difficult to develop for the following main reasons: 1. In most cases, operators of freight services over railroad networks, at railroad-owned network links, at port termi- nals, and along inland waterway networks are private firms answering to their shareholders, not Federal or state agencies. They have different funding criteria and market incentives from those more familiar to state transportation departments. 2. Estimating the “national value” of freight mobility de- bottlenecking is terra incognita for private network investors and operators. Benefit calculations for these firms would feature private returns, not social benefits or external economies and diseconomies. 3. Railways, ports, and inland waterways freight projects, especially those thought to exhibit “national value,” are likely to be “high cost, multi-year” initiatives, rather than activities that are “low cost, quickly implementable” in scope. A recent study (45) on the rail freight capacity identified the major rail bottlenecks within the rail network. Figure 29 shows the locations of some of the major bottlenecks and corridors. Table 32 shows the characteristics of some improvement pro- grams and projects that are either under way or planned for these bottlenecks. These programs are joint public and private stakeholder cooperative initiatives with the primary objectives of reducing congestion and delays on rail and highways, improving efficiency in freight and passenger mobility, enhanc- ing safety, and reducing air emissions. Information gathered through literature reviews, interviews, and survey of stakeholders indicate that some of the most severe and persistent rail freight mobility constraints include the following: • Outdated communication and signaling systems including signaling restrictions • Switching inefficiency including conflicts for mixed-speed operation on single or dual tracks • Inadequate sidings to accommodate train lengths • Inadequate capacity of yards and port terminals. Figure 29. Major chokepoints in rail freight network (45).

82 As noted in Table 32, rail capacity improvements gener- ally require large capital investments and such projects do not satisfy the criteria for low-cost improvements. However, elements of such large improvement programs are amenable to low-cost actions and have significant improvements in freight mobility. Furthermore, these actions can be imple- mented anywhere on the rail network to address freight mobility constraints, especially at major choke points. The second step therefore is to identify improvements that can be implemented alone or as part of major improvements. For example, the CREATE program assembles a number of projects that are designed to improve freight and passenger train as well as highway traffic movements. Projects under this program that could be classified as low-cost improve- ments are: • CREATE Project EW-4: BRC/NS Signal Upgrade—This project upgraded the Belt Railway Company of Chicago (BRC) and Norfolk Southern (NS) signal systems to power switches and signals along a segment of track. The result is increased train speed from 10 to 20 miles per hour; this segment now can handle twice the number of trains, an increase from 23 to 46 freight trains per day (29). • Deval Interlocking Replacement—The Deval interlocking machine in Des Plaines, Illinois, where several rail lines cross was replaced to improve operations by allowing the opera- tor to remotely view the entire interlocking area on a com- puter screen (29). • CREATE Project WA-5: Upgrade and Reconfigure Cor- with Interlocking and Remote CN Corwith Tower—This project installed a new signal bridge at Corwith Yard as part of CREATE improvements. The results are increased move- ments in and out of the yard and increased train lengths at the connection with NS and CSXT from 5,400 feet to 8,000 feet. Train speeds through the interlocking are increased, and the speed of interchanges between BNSF and its partner railroads is improved (29). The examples of low-cost improvements described for the CREATE projects and similar actions that have been proven to be effective in addressing rail freight mobility constraints and have the potential for nationwide applicability are included in the catalog presented in Table 33. These actions are derived from applying the methodology to different pos- sible scenarios focusing on those applicable to the top bottle- necks of the freight transportation system. The strategies are aligned to the constraints that they have been deployed to address. 7.2.3 Deepwater Ports and Inland Waterways The occurrence of a freight mobility constraint at a deep- water port terminal or an inland waterway system is deter- mined to a large extent by freight demand and capacity of the facility to handle existing demand. In identifying the deep- water ports that experience congestion and other freight mobil- ity constraints, the volume of freight passing through each port measured by the tonnage of freight handled is used to indicate the probable severity of mobility constraints. Table 34 shows the ranking of the top 25 ports in the United States for 2008 (95). Figure 30 shows the locations of these ports and tonnage of freight handled based on 2006 data (96). Constraint Constraint Description Improvements O pe ra tio na l C on st ra in ts Switching Conflicts/ Inefficient Switching Inefficient and inadequate switching and conflicts causing delays to trains • Upgrade or reconfigure interlocking — Interlocking is an arrangement of signal apparatus that prevents conflicting movements through an arrangement of tracks such as junctions or crossings. • Implement remote switching • Coordination of Class I ope rations with short - line/regional railroad operations to optimize joint operations and expedite switching traffic at interchanges.

Top 25 ports in terms of tonnage (2008) (95). As noted earlier, the following freight mobility constraints are identified as often encountered at the port terminals: • Inadequate terminal capacity • Physical barriers to rail operations • Empty container storage and movement • Inadequate local street and highway access from terminal • Inadequate waterway or channel depths • Inefficient terminal layout or terminal operations • Loss of communication on inland waterways in rural areas. These constraints occur “on the terminal” and “outside the gate.” Actions satisfying the criteria of low-cost and quickly implementable improvements and which might be of national significance would include operational/technology and regu- latory oriented actions. Freight mobility improvement projects and programs for deepwater ports and inland waterways gen- erally involve large capital investments that invariably are funded by private industry. It is also recognized that each port is unique where improvements at one location may not neces- sarily yield similar results at another port. Table 35 presents examples of programs that have been implemented to improve freight mobility and reduce con- gestion at some deepwater ports. These programs are prima- rily operational or technological actions designed to reduce congestion and delays to trucks and improve efficiency in container movements to and from the ports. Some programs are incentive-type programs designed to influence demand and consequently reduce the impacts on congestion. These strategies are of national value because, potentially, they can be implemented at any port in the country with similar results. Table 36 shows the list of low-cost improvements to address freight mobility constraints at deepwater ports and inland waterways. These actions are derived from the database of implemented projects that underlies the methodology.

Program Summary of Program Where Implemented Incentive-based congestion pricing to encourage off-peak movements, e.g., PierPASS (38) The PierPASS OffPeak program is a private-sector initiative, incentive-based program to shift movement of international containers from peak weekday hours to evenings and weekends. Ports of Los Angeles and Long Beach, California Incentive-based program to shift freight from trucks to rail, e.g., ExpressRail (97) ExpressRail—incentive program to encourage shippers to use rail rather than trucks for moving cargo through the Port. The program pays $25 per container shipped by rail to any ocean carrier that increases the number of containers it transports over its 2008 levels. Port Authority of New York/New Jersey Maximize infrastructure and equipment utilization through cooperative competitor arrangements, e.g., Chassis pool (98) Hampton Roads Container Pool II (HRCP-2), shipping lines provide chassis for the pool which are available for use by truck drivers who do not have to switch chassis to haul for different shipping lines. Norfolk, Virginia Maximize infrastructure utilization through cooperative competitor arrangements, e.g., Rail Yard Cargo Shift (99) Union Pacific Railroad is shifting its domestic intermodal container business from the Port of Seattle’s Argo Rail Yard to Tacoma, renting 10 acres of land across from the Port of Tacoma’s South Intermodal Yard. Ports of Seattle and Tacoma, Washington Table 35. Examples of programs with low-cost components.
