Just like any other scientific research field, the value of data quality is undisputed in the field of transportation. From policy planning to performance evaluation, from model development to impact studies, good quality data is essential to generate ideas and clear-cut sol u t ions to be implemented by transportation professionals and decision makers.
<p>This report presents a design for an electronic permit issuance system for overdimensional and/or overweight vehicles with nondivisible loads. The system has been designed in collaboration with, and for use by, the New York State Department of Transportation (NYSDOT), but the major elements of the design (if not the specific details) should be transferrable to other states or agencies.</p>
Speed limits have been introduced for many reasons, e.g., to reduce gas consumption, to reduce the frequency and severity
of crashes, and in some cases to reduce noise. The objective of this research effort was to conduct a literature review to
assess the effect of increased speed limits on limited access roads regarding safety, travel speeds, and other unanticipated
impacts including shifts in lane distribution, traffic diversions, and spillover effects. Following are the conclusions:
In 1974, a national maximum speed limit (NMSL) of 55
mph was introduced to reduce the consumption of fuel.
NMSL was followed by a dramatic reduction in the
number of fatal crashes and Congress decided to
continue with the 55 mph speed limit. In 1987, states
were allowed to increase the speed limit to 65 mph on
certain rural interstates. New Jersey did not change the
55 speed limit at that time since 'very little mileage
qualified as rural interstate.' In May 1998, New Jersey
<p>Growth in the population of older adults (age 60 and above) in coming years will challenge urban planners and transportation managers to provide travel options that support autonomy. To investigate barriers that older adults experience in using public transit, this research explores associations between older adults who do and do not ride fixed-route public transit and their neighborhood walking access to buses and trains.
