Every year MDOT invests millions of dollars into testing geomaterials, digitizing historic records and capturing inventory and condition data. Massive amounts of tabular data, documentation and imagery, which are relevant for planning and engineering purposes, continue to be accumulated. The engineering characteristics of pavement or other materials can be...

This resource is intended to inform discussions about on-street parking and bikeway selection. It is a supplementary resource to the FHWA Bikeway Selection Guide. It begins with a discussion of on-street parking and bikeway types, with associated dimensional requirements and trade-off considerations. It then presents several strategies involving choices...

The roughness experienced at bridge approaches and departures, generally termed the bump at the end of the bridge (BEB), has been identified as one of the most prominent issues in the transportation industry. The BEB is usually detected qualitatively based on road user feedback, with maintenance strategies subsequently implemented to improve ride quality. The...

Several controlled laboratory studies have shown that air voids (AV) can have a large effect on the performance of asphalt pavements. AVs that are either too high or too low can cause a reduction in pavement life. The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 299: Investigating the Relationship of As-Constructed Asphalt...

The ability to accurately predict vehicle trajectories is essential in infrastructure-based safety systems that aim to identify critical events such as near-crash situations and traffic violations. In a connected environment, important information about these critical events can be communicated to road users or the infrastructure to avoid or mitigate potential...

The purpose of this report is to document a simulation-based case study completed by the project team to investigate the effectiveness of SAE J3016 Level 1 automation technology for mitigating or solving existing transportation problems related to congestion, fuel consumption, and emissions (SAE International 2016). The case study conducted simulations on a...

The transportation system is undergoing three revolutions: vehicle automation, electrification, and shared mobility. While these are still nascent trends, studies suggest that they could become ubiquitous in the coming decades. How these revolutionary changes transpire will have significant implications for transportation sustainability. A key factor will be...

Local and regional planners struggle to keep up with rapid changes in mobility patterns. This exploratory research is framed with the overarching goal of asking if and how geo-social network data (GSND), in this case, Twitter data, can be used to understand and explain commuting and non-commuting travel patterns. The research project set out to determine...

Several types of speed limits exist, including statutory speed limit, posted speed limit, school zone speed limit, work zone speed limit, variable speed limit, and advisory speed. The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 291: Development of a Posted Speed Limit Setting Procedure and Tool documents the research efforts...

This report provides an approach for estimating present serviceability rating (PSR) from measured surface distress data to report overall pavement condition, where permitted, to support implementation of the National Performance Management Measures. The National Performance Management Measures; Assessing Pavement Condition for the National Highway Performance...
