Se trata el problema de la circulación en la Ciudad de México. Se asevera que el problema es debido en parte a la realización simultanea de varios proyectos importantes de construcción vial. Se informa que la aglomeración dura hasta 13 horas al día, según investigadores de la Universidad Nacional Autónoma de México (UNAM). Se sugiere que los problemas de circulación tienen un efecto negativo en el comercio en la ciudad.

The article reports that a New Jersey highway project turns a traffic jam into an open space plan for neighboring residents. In the middle-1990s, the New Jersey Department of Transportation (NJDOT) recognized that the situation was unacceptable from the traffic, environmental and human perspective and undertook the Route 29 tunnel and its companion deck park project to ensure efficient traffic operations and improve the quality of life in the area. The Route 29 South Riverwalk Park, which has become the focal point of the Trenton waterfront, was constructed on the roof of a cut-and-cover tunnel section of Route 29. Landscape architects developed a series of arched structures, each designed to be evocative of the century it represents, and located in an octagonal area representing that century. In addition to NJDOT's Route 29 park, Trenton is performing planning, design and coordination services for a number of interrelated park projects along the Delaware River waterfront. These include a one-mile pedestrian path and bikeway, and reconstruction of an existing fishing wharf and park.

Provides information on the success of a road project in Indianapolis, Indiana dubbed as Hyperfix 65/70. Changes made in anticipation of the heavy traffic; Program launched to alleviate congestion and offer an alternative for commuters heading downtown; Role of media in the road project; Details of the construction process.

This article reports that traffic should flow best in cities when only a limited number of roads lead to the centre. This counter-intuitive finding could allow planners to prevent gridlock by closing roads rather than building new ones. It comes from a new way of thinking about complex networks developed by researchers Neil Johnson, Douglas Ashton and Timothy Jarrett at the University of Oxford. The researchers began by approximating a complex city network to just a ring road and a number of the arterial roads that cross at the centre.

The article presents a case study on the installation of a wire-rope guardrail along Hume Highway in Australia. It is stated that the project at Hume Highway required ongoing diversion and delineation of traffic as work was going on. The contractor for the project needed to open and close the work zone to address traffic patterns and congestion problems. The Movable Vulcan Barrier from Quixote Transportation Safety Inc. was chosen as an alternative to the traditional concrete barrier.

The article discusses the action taken by the government of Mexico City, Mexico to solve traffic congestion in the city. It has begun a two-billion-peso project to build a series of two-tier motorways: double-decker bypasses that will eventually grow to a total length of 35 kilometres. This follows an initiative to reorganise the city's roads in the 1970s, in which the city widened the main avenues into four- and five-lane highways, known as ejes viales, and at the same time making the majority of streets one way.

The author reflects on the importance of color coding on direction signs helping to solve highway hodgepodge. He argues that the U.S. is becoming acutely conscious of the need for a vast speed-up in modern highway construction. He suggests that this color guide should be of considerable benefit even to the extent of employing secondary routes for the purpose of relieving traffic congestion.
