Transportation Research Part A: Policy and Practice is a bimonthly peer-reviewed scientific journal covering research on transportation policy and related issues. [1] It was established in 1979 as Transportation Research Part A: General, obtaining its current name in 1992.
Used to determine the distance headway between a vehicle and its predecessor. One of the simplest model in this category is the Pipe's rule, the basic assumption of this model is "A good rule for following another vehicle at a safe distance is to allow yourself at least the length of a car between your vehicle and the vehicle ahead for every ten miles per hour (16.1 km/h) of speed at which you ...
Traffic simulation or the simulation of transportation systems is the mathematical modeling of transportation systems (e.g., freeway junctions, arterial routes, roundabouts, downtown grid systems, etc.) through the application of computer software to better help plan, design, and operate transportation systems.

Traffic comprises pedestrians, vehicles, ridden or herded animals, trains, and other conveyances that use public ways (roads/sidewalks) for travel and transportation. Traffic laws govern and regulate traffic, while rules of the road include traffic laws and informal rules that may have developed over time to facilitate the orderly and timely ...
The GEH formula is useful in situations such as the following: [4] [5] [6] Comparing a set of traffic volumes from manual traffic counts with a set of volumes done at the same locations using automation (e.g. a pneumatic tube traffic counter is used to check the total entering volumes at an intersection to affirm the work done by technicians doing a manual count of the turn volumes).

The National Cooperative Highway Research Program was established in 1962 under TRB. Governments needed to tackle what Rex M. Whitton termed “clearly a supreme challenge to research”: moving people and goods in cities by using a fixed percentage of highway funding dedicated to research.
In transportation engineering, traffic flow is the study of interactions between travellers (including pedestrians, cyclists, drivers, and their vehicles) and infrastructure (including highways, signage, and traffic control devices), with the aim of understanding and developing an optimal transport network with efficient movement of traffic and minimal traffic congestion problems.
