The spacing of traffic signals-in terms of frequency and uniformity-governs the performance
of urban and suburban highways. Signals account for most of the delay that motorists …

Right turn plus U-turn at median openings as an alternative to direct left turn has been
considered important issue in access management. The motivation behind using this …

The objective of this research project was to develop a methodology for evaluating
alternative midblock left-turn treatments on urban and suburban arterials. The methodology …

This synthesis report will be of interest to roadway geometric design, safety, and operations
engineers, researchers, and managers. It reviews and summarizes selected geometric …

As part of a larger effort to develop guidelines for the design of arterial roads in areas
undergoing suburbanization, a safety analysis of median design was undertaken using …

In the decade since 2007, public bikeshare systems (PBS) have disrupted the landscape of
urban transportation systems all over the world. The rapid pace at which urban systems are …

Highway projects involving access management strategies are among the most hotly
debated transportation issues. In particular, the choice of midblock left turn treatment is a …

Accommodating left turns at unsignalized intersections is one of the most challenging
problems in traffic engineering. Over the last forty years, a small number of studies …

Trip Generation is the first step in the conventional four-step transportation demand
forecasting process. Trip generation is followed by trip distribution, mode choice, and route …

A simulation based on VISSIM and its external driver model dynamic link library (DLL) was
used to investigate the efficiency and safety of a two-way left-turn lane (TWLTL) on roads …
