question
Speculate on which method of relocating "unlocated" network stops would be most accurate for analysis purposes.
answer
Increasing the Search Tolerance for establishing a location in the network would probably be the most accurate. The other option is to manually move a location closer to a network segment in the map. The manual method relies on user ability to relocate the stop or facility and would probably be subject to a higher level of error than specifying for Network Analyst to extend the search radius.
question
Explain the importance of having speed limit data to be used in network analysis.
answer
The inclusion of speed limit data in a network data layer allows for travel costs in terms of time to be included in analysis. Speed limit data can be used with network segment length to determine the travel time for each line segment in a network. This is important for scenarios where time cost is more important than distance cost such as in 911 and other emergency scenarios.
