Pedestrian scrambleA pedestrian scramble, also known as scramble intersection and scramble corner (Canada), 'X' Crossing (UK), diagonal crossing (US), scramble crossing (Japan), exclusive pedestrian interval, or Barnes Dance, is a type of traffic signal movement that temporarily stops all vehicular traffic, thereby allowing pedestrians to cross an intersection in every direction, including diagonally, at the same time. In Canada and the United States, It was first used in the late 1940s, but it later fell out of favor with traffic engineers there, as it increases delay for pedestrians and drivers.

Un plan hippodamien ou hippodaméen (dit aussi milésien, en damier, en échiquier, quadrillé, ou orthogonal), est, en urbanisme, un type d'organisation de la ville dans lequel les rues sont rectilignes et se croisent en angle droit, créant des îlots de forme carrée ou rectangulaire.
Right-in/right-outRight-in/right-out (RIRO) and left-in/left-out (LILO) refer to a type of three-way road intersection where turning movements of vehicles are restricted. A RIRO permits only right turns and a LILO permits only left turns. "Right-in" and "left-in" refer to turns from a main road into an intersection (or a driveway or parcel); "right-out" and "left-out" refer to turns from an intersection (or a driveway or parcel) to a main road. RIRO is typical when vehicles drive on the right, and LILO is usual where vehicles drive on the left.
Dirt roadA dirt road or track is a type of unpaved road not paved with asphalt, concrete, brick, or stone; made from the native material of the land surface through which it passes, known to highway engineers as subgrade material. Terms similar to dirt road are dry-weather road, earth road, or the "Class Four Highway" designation used in China. A track, dirt track, or earth track would normally be similar but less suitable for larger vehicles—the distinction is not well-defined.
ObstacleAn obstacle (also called a barrier, impediment, or stumbling block) is an object, thing, action or situation that causes an obstruction. Different types of obstacles include physical, economic, biopsychosocial, cultural, political, technological and military. As physical obstacles, we can enumerate all those physical barriers that block the action and prevent the progress or the achievement of a concrete goal.

Road debrisRoad debris, a form of road hazard, is debris on or off a road. Road debris includes substances, materials, and objects that are foreign to the normal roadway environment. Debris may be produced by vehicular or non-vehicular sources, but in all cases it is considered litter, a form of solid waste. Debris may tend to collect in areas where vehicles do not drive, such as on the edges (shoulder), around traffic islands, and junctions. Road spray or tire kickup is road debris (usually liquid water) that has been kicked up, pushed out, or sprayed out from a tire.
Borne routièreUne borne routière est un élément signalétique placé régulièrement en bordure de route et destiné à identifier la route concernée et à y indiquer les distances, le plus souvent vers les localités voisines. En France, les bornes routières équipent les anciens réseaux nationaux, les réseaux départementaux et autoroutiers. Elles sont entrées dans le langage familier comme synonyme de kilomètre parcouru, parfois à tort, car elles ne tiennent pas toujours compte des derniers aménagements et tracés routiers et n'indiquent pas nécessairement des distances kilométriques exactes.
Vehicular communication systemsVehicular communication systems are computer networks in which vehicles and roadside units are the communicating nodes, providing each other with information, such as safety warnings and traffic information. They can be effective in avoiding accidents and traffic congestion. Both types of nodes are dedicated short-range communications (DSRC) devices. DSRC works in 5.9 GHz band with bandwidth of 75 MHz and approximate range of . Vehicular communications is usually developed as a part of intelligent transportation systems (ITS).
Piste (voirie)Une piste est un type de voirie destinée à la circulation piétonne ou de véhicules, qui présente un aspect minéral, sans être revêtue (par exemple par un enrobé). La piste aura des propriétés diverses selon le terrain qui la supporte. Elle peut apparaître par exemple sous forme de piste de graviers ou de latérite. Les appellations locales varient, en anglais, en espagnol. Contrairement aux voies revêtues, la traficabilité de telles voies peut fortement dépendre de la météo.
