How to write the sum up section of literature review?

Case 1

To sum up, microscopic traffic simulation has been widely adopted in assessing the benefits of CACC. （类型）

Simulation study, however, is not without its caveats, and calibration of the simulation network is one of the them. Besides a proven microscopic behavioral model, the simulation network has to be first calibrated using real-world traffic data to ensure the validity of the simulation results. Not only the global macroscopic traffic flow characteristics (e.g., corridor travel time), but also the local traffic phenomena (e.g., bottlenecks, queues, speed-flow patterns) should be reproduced in the simulation to ensure a good representation of the real-world traffic conditions. （缺点和解决）

Recently studies revealed the shifted attention to evaluating the interaction between CACC and non-equipped vehicles, as well as the operational strategy that can harness the benefits of CACC in mixed traffic conditions. The coordination among CAVs to form vehicular platoons as an operational strategy has shown potential in boosting CACC benefits when the MPR is low. （趋势和缺点）However, its potential negative impact due to induced lane change has not been investigated at the vehicle trajectory level.

Case 2

In summary, previous studies have proved that CADVs significantly impact traffic flow, and studies on traffic flow mixed with CADVs can help improve traffic safety. Therefore, taking the mixed traffic flow composed of manual driving vehicles, CADVs, and FADVs as the research object, this paper analyzes the effect of CADVs on the mixed traffic flow from the perspective of different takeover times and the given takeover time, respectively.
