Analysis of Traffic Evolution on Road Networks of a Roundabout

Figure 7

Density and flux profiles on the entrance and main lane of a roundabout in case 2. Due to traffic congestion, shock waves are produced on roads () in the case of (a) and on () in the case of (c) with corresponding fluxes as shown in (b) and (d), respectively.

(a) Density on the entrances road in case 2

(b) Flux on the entrances road in case 2

(c) Density between the diverging and merging main lane of the roundabout in case 2

(d) Flux between the diverging and merging main lane of the roundabout in case 2
