From 2006 to 2014, ten right‐turn approaches in the Peoria, Illinois, area were selected and reconstructed with a modified right‐turn lane design. The major purpose of the modified design was to improve the line of sight for passenger vehicles attempting to turn right, while also accommodating semi‐tractor trailer trucks. While the actual changes varied among...

Bridge performance measures are important components of any successful Bridge Management System. Different types of performance measures have been developed for various purposes. The types of performance measures are usually a reflection of an agency’s goals. The bridge health or condition index is a type of performance measure used by agencies interested...

When more cyclists turn to the roads in Oslo each spring, the risk for each cyclist of being involved in a conflict or near miss is reduced. In other words, there is proof of a Safety in Numbers effect. Comparing Norwegian road users with their Danish and Swedish counterparts shows that this effect can either be accentuated or reduced by differences in...

This TRB report documents the state of the practice of life-cycle cost analysis (LCCA) and risk-based analysis into state highway agencies' asset management plans for pavements and bridges on the National Highway System. The objective of this project was to develop an inventory of quantitative asset-level, project-level, or corridor-level processes and...

This synthesis documents transit agency parking policies and parking management at transit stations using three primary resources: a scan of current research on transit-supportive parking policies, an original survey distributed to a sample of transit agencies, and several brief agency profiles based on interviews and existing available data. The survey was...

This report synthesizes the current service limit state (SLS) design and analyses of engineered fills for bridge support used as shallow foundations. The SLS for settlement and deformations of bridge supports are summarized. Extensive literature reviews were conducted to synthesize the effects of various parameters on the SLS of engineered fills. The...

Mobility is central to living an independent life, to participating in society, and to maintaining well-being in later life. The point of departure in this thesis is that retirement implies changes in time-space use and interruption in routines, which influence demands and preconditions for mobility in different ways.  The aim of this thesis is to explore...
