PART IV: Summary of Comments17-May-10Reviewer Comments Distribution of RatingsItem #52:B-07Real-Time Information: Quantifying Traveler Benefitsand Effects on Transportation Demand(17)(46)NR 0 1 2 3 4 5SCOR 1 3 7 5 1RAC 1 1 3 10 12 17 5Standing Committee on Research■ It will be extremely difficult to quantify many of the effects of many of these countermeasures in a way that can begeneralized across locations. While this is an area where research is needed, the effects are likely to be very site specific.I believe the current scope will likely produce a "more research is needed" finding with little implementation value.■ Should look at the downsides also.■ Only restriction is availability of data■ The project sounds like a good idea but may be difficult to accomplish if the data needed is not readily available.■ [Rating: 4] In the Problem Statement, the 2nd bullet starts out good, but then focuses only on the question of investmentsin en-route information, as opposed to pre-trip & near-trip also. The objectives do not make this distinction so it isimportant to be sure that whole spectrum of providing information and the impacts on demand (which arguably could begreatest with pre-trip) is addressed.Research Advisory Committee■ The emerging use of technology could be very useful for traffic control and the public's real-time transportation choices.Quantifying its benefits would help justify funding.■ There is a value to assessing and quantifying the current benefits of different mechanisms for travel information toprovide Agencies information from which to base decisions. I agree that the scope needs to be narrowed to the optionsfor complicated systems versus simpler means. It would be more realistic to assess how specific types of systems areproviding benefits in different markets. The overall benefits of traveler information infrastructure can exceed the dailytally when emergency management practices or other mass communication needs (Amber Alert, etc) are employed. Anassessment of the cost-benefits should include some consideration about how each technology also meets the overallneeds of society. Much like a hospital and its testing equipment, these are only beneficial if needed, but when needed canbe essential. In addition, there are additional benefits to providing assistance/ information to the public and publicperception of government that traveler information systems provide. Therefore this research should provide pieces ofvaluable information on individual technologies, but a much bigger project would be needed to assess the value of realtimeinformation systems.Other■ Complements SHRP 2 Reliability focus area, especially L11 and L14Item #53:B-01Combining Data Collection for State DOT’s ExistingManagement Systems and HPMS Submittals(17)(46)NR 0 1 2 3 4 5SCOR 6 5 6RAC 1 1 11 15 15 6Standing Committee on Research■ Data collection for various systems within a DOT represent a significant investment (or aren't done well.) Consolidatingrequirements would ease the burden and encourage better data programs.■ Should integrate all management systems.■ Suggest synthesis; some states do combine data collection very well already■ Envisioned research product is not clear■ We feel that we have a pretty good handle on this and don't see the benefit of the research.IV-36
PART IV: Summary of Comments17-May-10Reviewer Comments Distribution of Ratings■ Could be possible ADOT benefit■ [Rating: 4] Timely study in light of the much enhanced HPMS data requirements. Will help improve efficiency, reduceredundancy and improve accuracy of HPMS data. Should include all management systems, including pavementmanagement system. The guide should also address how the changes would impact the use of legacy data and methodsto overcome them.Research Advisory Committee■ Appears good to combine efforts, but the biggest problem could be the collection of data. Example: Some informationrequires specialized employees (condition ratings, etc..) and other data items just require ordinary employees. Ordinaryemployees can't perform specialized work (incorrect data) and your wasting specialized experience (money) collectingbasic information. Also from experience, an employee can only collect so much information (data items) before thequality of information erodes.■ Previous studies did not show good correlations for this also a lot of programs are driven by policies that are notconsistent between States. FHWA should enforce processes and procedures first before undertaking such a study.■ Very few if any similar data items collected for HPMS that are also collected for maintenance needs.Other■ [Rating: 4] Priority #5■ [Rating: 2] Envisioned end product is not clearItem #54:C-02System Performance of Accelerated BridgeConstruction (ABC) Connections in Moderate-to-HighSeismic Regions(17)(46)NR 0 1 2 3 4 5SCOR 1 3 4 7 2RAC 1 5 8 5 13 9 8Standing Committee on Research■ Results would only benefit DOT's that have to design for high seismic events. Additional research on ABC connectionsis needed.■ Limited use for states not in seismic zone■ This research is critical to the implementation of Accelerated Bridge Construction (ABC) practices using prefabricatedelements in California and other states with seismic or other extreme event hazards. ABC innovations will result inreduced project delivery time, reduced construction impacts to the travelling public, and improved work zone safety.■ [Rating: 3] Although the research may be needed, the results may only be beneficial to a narrow band of states. Inaddition, the problem statement appears ambitious for the requested funding level considering the current funding/focusof NCHRP 12-74.Research Advisory Committee■ With a national focus on ABC, the major hindrance to its widespread implementation is the uncertainty regarding theperformance of seismic connections. This research will answer a lot of unknowns.■ Benefit to seismic regions■ Important topic for earthquake areas. (Design■ As Evaluation panel previously noted, this problem is a current need for seismic states. This research may not get donewithin 36 months, due to broad scope of work that needs to be done.■IV-37
