When two or more upstream lanes are connected to a single downstream lane, a merging area is defined. In the merging area, additional caution is required on the part of motorists because vehicles from the two lanes may need to co-ordinate with each other. Merging is classified into (1) priority merging and (ii) non-priority merging. Priority merging includes merging from minor streets to major streets. Non-priority merging typically occurs at the downstream of toll plazas and lane drops on freeways.
Why Is Access Management Necessary? Constantly growing traffic congestion, concerns over traffic safety, and the ever-increasing cost of upgrading the islands roads have generated a new interest in managing the access to our highway system.
