questions using noun phrases or short sentences in your own words.
1. What’s the main idea of each paragraph?
Para 1: Importance of the development of path planning algorithms
Para 2: The practical applications of path finding strategies
Para 3: The development history of dynamic shortest path finding
Para 4: The insufficiency of basic algorithms and strategies
Para 5: Previous studies on dynamic factors in path finding
Para 6: The research on the management of traffic network uncertainty
Para 7: Problems with path finding algorithms to be solved
Para 8: The strategy to deal with link failure dependence
2. What problems existing in the path finding algorithms and route planning strategies
have been identified in the following paragraphs?
Para 4: Insufficiency to solve real life problems in dynamic and uncertain scenarios.
Para 5: Difficulty in defining and measuring reliability
Para 7: An over-saturated state due to great demand of links, resulting in traffic
congestion.
Para 8: The classification proves to be inaccurate
3. What solution has been proposed to solve the identified problems? Or in other words,
what is the objective of this proposal?
3.1 To develop theoretical models to assess and predict traffic network
conditions based on hyper-path Strategies
