System for carrying out secondary development on TransCAD based on GISDK platform

The invention discloses a system for carrying out secondary development on a TransCAD based on a GISDK platform. The system comprises a road network time-space resource metering module, a time-space resource consumption calculation module and a land area rate optimization module, wherein the road network time-space resource metering module is used for metering the amount of service resources, which can be provided by a road network, and carrying out quantitative evaluation on a road time-space resource; the time-space resource consumption calculation module is used for calculating the consumption of time-space resources according to introduced planned initial data and a driving speed of a vehicle on a region road network, calculating a resource utilization rate and a residual service capability of the road network according to the consumed time-space resources, and judging a traffic condition of roads according to a calculation result, and the traffic condition is taken as an evidence of judging whether an op
