Study Description

The capability of Connected and Autonomous Vehicles (CAV) is progressing at a faster rate with particular focus on technological performance, and its wide-ranging potential impacts on safety, operation, and regulatory issues. For example, CAVs could travel closer together at smaller headway which enables higher capacity through existing infrastructure. Existing CAV research is often limited in terms of scope, scale, approach, or underlying assumptions, and has not sufficiently addressed questions about the large-scale impacts of CAV on highway capacity, which are required by decision-makers to inform policies.

Moreover, the Highway Capacity Manual (HCM) is at risk of becoming outdated or limited in relevance/usefulness as the CAV technologies become more prevalent on the market. The current HCM has multiple limitations regarding CAV analysis including:

(1) Capacity-related HCM methods cannot be used to evaluate projects or facilities that would utilize CAV technology,

as the impacts of CAV strategies are not accounted for.

(2) Lack of existing analysis guidance regarding the suitability of the HCM for analyses involving CAV strategies.

(3) Limited consideration of market penetration and the effects they will have on the realized outcomes associated with

CAV technologies on various facilities.

These limitations drive a critical need to develop HCM capacity adjustments (CCAV) to be prepared for future CAV operations under varying levels of volume and market penetration.

Objectives

Phase II Objectives: The HCM CAV pooled fund study is on track to meet all original study goals within the year 1 and 2 scope, and has successfully developed CAV adjustment factors for the HCM. This extension scope builds on the existing work with a primary focus on technology transfer, dissemination of results, and training. The specific tasks proposed for the Year 3 extension are as follows:

• Task A: Scenario Development

• Task B: Training Materials

• Task C: Outreach and Webinars

Scope of Work

Task A: Scenario Development

This task will develop a set of five scenarios that illustrate the application of the capacity adjustment factors to typical planning use cases an agency faces. The goal of this task is to show how the factors should be used for planning applications, but also illustrate limitations and potential mis-uses of the results.

1. CAV Freeway Management

Comparing CAV-only facilities for freeways, e.g., converting an existing managed lane facility, with a mixed-flow facility with CAVs and non-

CAV vehicles.

2. CAV Arterial Management

Evaluating effects of CAVs on arterial streets with and without CAV priority treatments.

3. Statewide Project Prioritization

Exploring how STIP programs may be impacted with consideration of CAV effects.

4. CAV Service Volume Tables

Showing how to develop custom CAV service volume tables for CAV application.

5. CAV in Travel Demand Modeling

Demonstrating how CAVs may be integrated in a travel demand modeling application

Task B: Training Materials

This task will develop training materials to summarize the results of the research and the Task A Scenarios for dissemination to state agencies. The task will prepare two sets of presentations: (1) a policy-level presentation intended to provide study highlights and implications for decision-makers; and (2) a practitioner-focused presentation intended to serve as a “how-to guide” for applying the methods and presenting detailed results.

Task C: Outreach and Webinars

This task will conduct outreach and technology transfer to key stakeholders in the form of webinars and in-person workshops. The team proposes the following activities:

- In-person presentation to the AASHTO Committees on Planning and Traffic Engineering;

- Five in-person workshops for state DOTs, covering both the policy-level and detailed content;

- Two nationally-broadcast webinars in collaboration with TRB, ITE, or other partners, with one focused on freeway results, and one focused on arterial results.

Comments

For full partner benefits, a 2-year funding commitment; $15K/yr (paid annually) assuming 5 agencies join the fund, with potential discounts for in kind contributions if necessary for participation.

Project TAC will determine statement of work and selection criteria.

2-yr road map developed/approved by TAC; non-consensus decided by majority rule.

Subjects: Highway Operations, Capacity, and Traffic Control Planning and Administration
