Evaluation of intersection conflict warning system at unsignalized intersections: A review

Journal of Traffic and Transportation Engineering (English Edition), 2023
Unsignalized intersections are identified as the critical locations due to higher number of road crashes at these locations. The primary causes of crashes at unsignalized intersections are limited sight distance, incorrect assessment of gaps by drivers ...

Development of a conflict-free unsignalized intersection organization method for multiple connected and autonomous vehicles. [PDF]

PLoS ONE, 2021
An effective traffic control strategy will improve travel reliability in urban transportation networks. Lack of coordination between vehicles, however, exacerbates congestion due mainly to frequent stops at unsignalized intersections. It is beneficial to

ANALYSIS OF THE UNSIGNALIZED INTERSECTION OF MUHARTO ROAD, KI AGENG GRIBIG ROAD, AND MAYJEND SUNGKONO ROAD [PDF]

Journal Innovation of Civil Engineering, 2023
Delays that occur at intersections greatly affect the performance of the road network. The more intersections there are, the greater the delay value will be. One of the intersections in Malang City is the three unsignalized intersections of Muharto Road,

Transport delay assessment at unsignalized intersections feeding focal points [PDF]

MATEC Web of Conferences, 2021
The article discusses the issues of assessing the delays connected with the transport service of people visiting focal points (FPs) by individual transport (IT). The necessity of using a mathematical approach when assessing delays is proved.
