A system to improve the management of through traffic and vehicles entering and exiting a multilane roadway. The lanes are separated by at least one lane separator which should not be crossed by traffic along a designated portion of the roadway, such as within a predetermined distance from a roadway entrance or exit. The at least one lane separator may be any lane marking, barrier, or the like. The at least one lane separator can be any length and located anywhere with respect to the lanes.

In one instance, a parking lot system is presented with a first driveway in a first direction and a second driveway in a second direction opposite the first direction. The first driveway includes a first plurality of parking spaces, wherein each parking space comprises a first rectangular space to accommodate an automobile. A second rectangle is adjacent to the first rectangular space. The second driveway includes a second plurality of parking spaces, wherein each parking space comprises a third rectangular space sized to accommodate an automobile. The second rectangle is adjacent to the third rectangle. The second rectangle forms a buffer zone into which automobile doors in the second and third rectangle may open. The first and second plurality of parking spaces at least partially abut one another directly. Other systems are also presented.

A system of active lane markers in a roadway, the active lane markers comprising sensors, transmitters and receivers to monitor the status of the roads and provide vehicle guidance to vehicles in response to analysis of sensor data.

The disclosed pavement marking system provides information about the arrangement of the pavement marking to a sensor on a vehicle for to identify a particular lane on a roadway. The pavement marking system comprises a sensor placed on a vehicle and at least a first pavement marking and a second pavement marking, wherein each of the first pavement marking a second pavement marking comprising different properties.

An infrastructure system includes at least one sensor, a transceiver, and a computer communicatively coupled to the at least one sensor and to the transceiver. The computer is programmed to receive data from the at least one sensor indicating respective locations and motions of objects in an environment surrounding the at least one sensor; in response to one of (a) the data from the at least one sensor or (b) a request from a user, generate a virtual traffic marker at a first location in the environment; and instruct the transceiver to broadcast the virtual traffic marker to vehicles in the environment. The first location is based on the data from the at least one sensor, and the virtual traffic marker is data including the first location and traffic instructions corresponding to the first location.
