Re-Creating NETC

Project Objectives

The research objectives of this project include:

Perform a robust self-evaluation of NETC, incorporating steps to improve the effectiveness of NETC.
Conduct a Strength, Weaknesses, Opportunities, Threats (SWOT) analyses to engage Transportation Agency Advisory Committee members in discussions examining the internal and external factors that are expected to impact NETC’s continued effectiveness in executing its research program.
Distribute online surveys to two member groups: NETC transportation agency managers and implementers, and NETC agency subject matter experts.
Distribute additional online surveys to pooled fund consortiums, university transportation centers) and cooperative research programs to gather information about administering a research program, selecting and prioritizing research, managing research projects, implementing research and communicating research results.
Discuss possible actions NETC could take and move toward consensus on the types of changes NETC could pursue.

20-4 Coordinating State Policies, Laws and Regulations for Automated Driving Systems Across New England

Project Objectives

The objectives of this project are to:

Conduct a literature review of research focused on Automated Driving Systems (ADS);
Analyze existing policy, legal, and regulatory issues to overcome anticipated barriers to multi-state ADS operations;
Recommend coordinated steps for the NE States to take in consideration of the operations of vehicles on the roadway transitioning from human driven to ADS operated;
Develop recommendations towards facilitating testing and deployment of ADS-equipped vehicles operating in multiple states or traveling across state lines; and
Support the development of policy, legal, and regulatory approaches that inform national and other regional ADS efforts.

20-1 In-Service Performance Evaluation of NETC Bridge Railings

Project Objectives

The research objective will be to determine the in-service performance of the NETC bridge railings and transition systems based on the percentage of fatal and serious injury crashes and barrier penetrations. The evaluation should examine all NETC bridge railing sites constructed in each cooperating state. Construction records and bridge inventories will be reviewed to develop an inventory of NETC bridge railings. Crash data for five years (and more if possible) will be collected for all NETC bridge railings identified in the inventory. Traffic data (e.g., posted speed limit, AADT and percent trucks) will also be collected, if available, for each inventoried NETC bridge rail. The crash, inventory and traffic data will be merged into a single database and the fatal and serious injury proportions will be calculated for each type of NETC railing by a variety of potentially confounding factors (e.g., posted speed limit, vehicle type, highway facility type, percent trucks, etc.). Similarly, the crash records will be examined for any indication of bridge railing penetration or rollover. This study should be conducted using the now available NCHRP 22-33 Guidance for the conduct of ISPEs. NCHRP 22-33 (Collaborative Approach to In-Service Performance Evaluations) has outlined an approach to the conduct of ISPEs which uses crash data to mimic the MASH evaluation criteria, thereby providing a direct comparison of actual field performance to the MASH evaluation criteria. Further, the NCHRP 22-33 Guidance was developed with the intent of collaborating across state lines to conduct more robust ISPEs just as is being proposed herein.

19-1 Curved Integral Abutment Bridge Design

Project Objectives

This project’s objective is to develop guidelines for the design of curved integral abutment bridges. These guidelines should address recommendations for span length, total bridge length and degree of curvature and skew, with modeling recommendations for design which are consistent with the current AASHTO LRFD Bridge Design Specifications.
