ACRP Report 40: Airport Curbside and Terminal Area Roadway Operations was published in 2010.  In the 10 years since it was published, the inception of ride sharing services has brought a paradigm shift, not only to the airport curb but to society in general.  Transportation Network Companies (TNCs) demonstrated the effectiveness of peer-to-peer mobile services so much so that new services are embracing this same model.  There are both opportunities and challenges in managing the different types of traditional and disruptive ground transportation service providers.  Uncertainty about the nature and timing of future disruptive ground transportation services will likely complicate airport planning activities.

The focus of ACRP Report 40 was on data gathering and analysis, but did not explicitly address planning, modifying, and operating roadways and curbsides to achieve maximum efficiency, safety, security, and customer service.  Curbs must accommodate various modes of access/egress, ranging from single occupant vehicles to large buses while accommodating important security issues at terminal curbsides.  Since the cost of adding curb can be significant (e.g., adding a second level), airports would benefit from identifying best practices for curb management (e.g., access prioritization, tolling, etc.) to increase existing capacity.  

Finally, airports are placing more of a focus on the customer experience.  At the same time, passenger traffic continues to grow.  Many airports are already experiencing significant congestion on their roadways and at the curb, often because of geographic location or land use constraints.  These two realities can be in conflict with each other and it has become challenging to expand the capacity of landside facilities to meet current and future demand while maintaining an acceptable level of customer service.


The objectives of this research are to produce a guidebook that is a thorough, user-friendly update of ACRP Report 40: Airport Curbside and Terminal Area Roadway Operations by (a) publishing an updated text based on the original guidebook; (b) reviewing and updating the associated analysis tools, including the Quick Analysis Tool for Airport Roadways (QATAR), for currency, relevance, and usability; (c) incorporating new information on recently implemented ground transportation services (e.g., TNCs, peer-to-peer services, etc.); (d) discussing how airports can anticipate future services (e.g., autonomous vehicles and other disruptive technologies) and design flexible landside spaces to accommodate those services; and (e) identifying scalable strategies for traffic demand and congestion management.

Scalable strategies for traffic demand and congestion management, must, at a minimum address: policy and regulatory issues, typical peak vs. irregular operations traffic demand, stakeholder engagement and possible political issues, and operational techniques and new technology being used by airports and ground transportation service providers.    


The ACRP is seeking the insights of proposers on how best to achieve the research objectives. Proposers are asked to develop and include a detailed research plan for accomplishing the project objectives. Proposers are expected to describe research plans that can realistically be accomplished within the constraints of available funds and contract time. Proposals must present the proposers' current thinking in sufficient detail to demonstrate their understanding of the issues and the soundness of their approach to meeting the research objectives. The work proposed must be divided into tasks and proposers must describe the work proposed in each task in detail. 

The research plan should build in appropriate checkpoints with the ACRP panel, including at a minimum (1) a kick-off teleconference meeting to be held within 1 month of the Notice to Proceed to review the amplified work plan, (2) a web-conference to review the draft data collection plan and draft case-study plan, (3) one in-person meeting that will occur midway in the project schedule, the date of which will be determined in the amplified work plan, and (4) web-enabled teleconferences tied to the panel review and ACRP approval of interim deliverables deemed appropriate. 

The research plan should include, at a minimum, appropriate interim deliverables that will require ACRP approval as follows: (1) a review and validation of the existing QATAR tool and existing default values within the guidebook as well as the development of default values for new services (e.g., TNCs, etc.); (2) a data-collection plan for making necessary updates that considers newly available datasets; (3) a research plan for identifying and evaluating demand and traffic-congestion management strategies taking into consideration, at a minimum, diversity in airport size, ground transportation service providers, operational configurations, etc.; (4) case studies that illustrate selected demand and traffic-congestion management strategies; and (5) a validation plan for the update to QATAR, and an expanded draft Table of Contents discussing how the new guidebook will build-on and refer to ACRP Report 40.

The final deliverables will include: (a) the updated guidebook with updated QATAR and other tools; (b) a summary of key findings (see Special Note D); (c) Further Recommended Research Memo (see Special Note E); and (5) a technical memo titled: “Implementation of Research Findings and Products” (see Special Note F).

Note: Following receipt of the draft final deliverables, there should be 3 months for ACRP review and comments and for contractor preparation of the final deliverables.   For budgeting purposes, proposers should assume that ACRP will provide access to web-enabled teleconference services.  ACRP will pay panel members’ travel costs for the one in-person meeting.  Proposers should assume that the meeting will be held in Washington, DC.


A. Proposals should present recent airport terminal roadway and curbside experience of their specific team members. 

B. Proposals should include a sample of sources that could be included in the literature review. This research should build on existing ACRP research, including but not limited to ACRP Report 146: Commercial Ground Transportation at Airports: Best Practices and ACRP Research Report 215 Pre-Publication: Transportation Network Companies (TNCs): Impacts to Airport Revenues and Operations. Additionally, the selected research team should plan to coordinate with the research team from ACRP Project 03-47, "Rethinking Airport Parking Facilities to Protect and Enhance Non-Aeronautical Revenue".

C. Airports have received many surveys in response to ACRP projects. In an effort to ensure an adequate response rate and collection of information, proposers may consider the use of focus groups, Internet/web-based technologies, social networking sites, and industry conferences or other techniques that may be appropriate.

D. The Summary of Key Findings will be a stand-alone document. It should (a) convey the most pertinent and applicable results of the project’s research, (b) be geared toward the airport industry practitioner while minimizing technical language, (c) present results using text and graphics as appropriate, and (d) encourage readers to explore the primary project deliverables. The Summary of Key Findings should be limited to no more than 4 pages.

E. The Further Recommended Research Memo will be a stand-alone document. It should (a) identify logical follow-on research that would benefit the industry yet was beyond the original scope and budget of the project; (b) describe how the proposed follow-on research relates to ACRP’s research roadmaps, if applicable; and (c) for the highest priority research needs, include research ideas and/or problem statements to be added to ACRP’s IdeaHub, the program’s online repository of research needs.
