[Abstract]:Traffic network expansion is the effective means to ease the traffic pressure on the network, and increase the new road is the main way of traffic network expansion, has important significance that how to add a new section of the road and how to measure traffic network performance. The existing studies on the effects of new road network mainly analyzes the road network topology increases (such as travel distance) changes, in fact, whether it is concerned with the traffic management department or who is not only the change in distance to travel new roads after the maximum amount of traffic through the road network within the care units (the maximum flow) and changes on the network total travel time and traffic network performance index but, existing research does not involve, in view of the above shortcomings, this study from the maximum flow of network topology and network, network topology and network traffic flow. In 2 aspects, put forward new measures of road section of the traffic network performance, and the definition and algorithm index; then design road principle and the corresponding algorithm is given; finally to Chengdu local network as an example, increase road traffic impact on the network performance verification of different principles, provide the basis for increasing strategy area road network for traffic management departments. The main work and innovation are as follows. The influence of new sections on traffic network performance from the maximum network flow and network topology structure of the combination of the angle measurement indexes, maximum flow network (FCAE), the new side of new road after the point on the network between the maximum flow and no new sections of the whole network on the difference between the maximum and the maximum flow of the boundary; and the total distance network (DCAE), the new side of new road after all A point to point network network shortest path length and no new sections of the entire network to the maximum difference between network shortest path length and the boundary, and the design of the above two indexes. Then the algorithm gives two principles: FCAE add edge edge addition principle, namely all options in the current network the edge of selected key network maximum flow added edge (FCAE) is added to the network, and DCAE by side principle, namely in the current network of all alternative edge selected total distance network key added edge (DCAE) is added to the network. Finally, taking Chengdu city of Chenghua District local traffic network as an example, to discuss the change of the total network the distance to the edge of FCAE increased gradually increase with the principle of road network maximum flow increasing, as well as DCAE increased gradually increase after the road side principle with the change of the maximum flow of network network due to the reduction of the total distance. The results showed that: in the preparation of the network Select the side taken 10 to 1 group 6 group cases, the total network distance to FCAE increased gradually increase with the principle of side section of the maximum flow of network increases gradually decreases with DCAE increasing; side principle gradually increased with the maximum flow of network link network due to the reduction in the total distance measurement index increased gradually. The influence of new sections on traffic network performance from the network topology and traffic equilibrium point of the combination of the optimal network access time (TCAE), the new key side of new road after the entire network total travel time and without the added edge maximum difference in total travel time of the sections of the entire network, and design the index algorithm. Then, TCAE side principle, namely in the current network side selects all alternative optimal network traffic time key added edge (TCAE) is added to the network. Finally, taking Chengdu city of Wuhou District local traffic network Network as an example, to discuss the principle of TCAE increased gradually increase after the road side with optimal network access time reduces the change caused by the network distance, as well as DCAE increased gradually increase after the principle of edge sections with the change of network optimal total distance network due to the reduction in the passage of time. The results showed that: in the network side choose 10 options a 1 group of 6 groups of cases with TCAE increased gradually increased with the principle of side road network optimal access time reduces the network distance to gradually decrease with DCAE increasing; side principle gradually increased along with the network road after the optimal total distance of the network due to the reduction in the passage of time gradually decreases.
