[citation needed] They are usually equipped with a C.B. radio, or other two-way radios to communicate with each other. [2] On a two-lane road, a load with one escort has the escort vehicle take position in front of the load being escorted. On a four (or more) lane road, the escort then transitions to a position behind the load being escorted. [3]
These acronyms differ from each other either in historical context, technology used, standard, or country (vehicle telematics, DSRC, WAVE, [17] VANET, IoV, 802.11p, ITS-G5, [18] V2X). Currently, cellular based on 3GPP-Release 16 [ 19 ] and WiFi based on IEEE 802.11p have proven to be potential communication technologies enabling connected vehicles.
Vehicle-to-person (V2P) includes Vulnerable Road User (VRU) scenarios to detect pedestrians and cyclists to avoid accident and injuries involving those road users. As both direct communication and wide area cellular network communication are defined in the same standard (3GPP), both modes of communication will likely be integrated into a single ...

The maximum interval is the maximum amount of time one road will be allowed a green signal, where demand is present on another road. [4] [9] For pedestrians, an invitation period is the period of time where pedestrians are invited to begin crossing the road. This is normally shown with a green or white male walking figure. [4]
Traffic culture is a determinant factor for the behaviors of all road users’ traffic. Specifically, it has a main role in crashes. [13] Some jurisdictions forbid crossing or using the road anywhere other than at crossings, termed jaywalking. In other areas, pedestrians may have the right to cross where they choose, and have right of way over ...
The Manual on Uniform Traffic Control Devices for Streets and Highways (usually referred to as the Manual on Uniform Traffic Control Devices, abbreviated MUTCD) is a document issued by the Federal Highway Administration (FHWA) of the United States Department of Transportation (USDOT) to specify the standards by which traffic signs, road surface markings, and signals are designed, installed ...
In the cases where a new motorway acts as a bypass of a state highway route, the original state highway is either stripped of that status or renumbered. A low road number means a road suitable for long-distance driving. In Belgium, motorways but also some dual carriageways have numbers preceded by an A. However, those that also have an E-number ...
