The objective of this synthesis is to document practices used by state departments of transportation (DOTs) for designing and maintaining roadsides adjacent to urban freeways. The synthesis focuses on high visibility freeway roadsides with limited pedestrian access. These areas often have wide medians, interchanges, and overpasses. Information used in this...

This paper compares the Public Private Partnership model for funding of infrastructure projects with an alternative approach, the Regulatory Asset Base model. It considers whether the ability to levy user charges is necessary to ensure low financing costs, or whether these stem from other factors. The paper is part of a series of 19 papers and a synthesis...

This report documents the work conducted under NCHRP Project 17-55 by the Texas A&M Transportation Institute. The researchers conducted 43,000 simulations for various combinations of roadside slope configurations and geometric conditions that represent real-world crash scenarios. The simulations were performed using vehicle models that represented a variety...

Pedestrian fatalities and injuries represent a growing percentage of all traffic fatalities and injuries. This project used amultifaceted approach to improving compliance to the Minnesota crosswalk law in Saint Paul, Minnesota, including: (1) education, (2) measurement, (3) enforcement efforts, (4) social norming, and (5) engineering treatment. The multifaceted...

In an effort to reduce the number of single vehicle run-off-road and two-lane two-way crossover crashes, TxDOT has implemented various audible lane departure warning systems on seal coat road surfaces. This 20-month research project explored the effectiveness of these various treatments using several performance metrics and provided recommendations on...

The objective of this study was to evaluate long-term aging effects on asphalt mixtures using the Illinois Flexibility Index Test (I-FIT) and to develop a corresponding long-term aging protocol. The study recommended the use of the forced-draft oven as the aging equipment because of its availability, feasibility, practicability, capacity, and acceptable...

When the sightlines along horizontal roadway curves are restricted, there are challenges to find acceptable solutions. Designers compensate for the limitations on driver sight distance in various ways, including: accepting shorter sightlines, lowering design speed, increasing shoulder width, or providing additional signage. There are advantages and...

Crack sealing is an important preventive treatment in the pavement preservation program. To achieve a cost-effective crack seal, it is important to select a proper crack sealing method. While Minnesota usually seals cracks in asphalt pavements, there is no clear consensus on the most appropriate crack sealing method for a specific job. This study focused on...

This research project was conducted with the objective of evaluating the viability of using an automated computer application to detect, classify, and quantify cracks on flexible and rigid pavement surfaces from digital images, to be implemented in the annual Pavement Condition Survey (PCS). Phase I of this project was focused on identification and...
