     Which of the following data types cannot be used to create a network dataset?

    • A.

      Geodatabase with multiple line feature classes

    • B.

      Geodatabase with subtypes

    • C.

      Shapefile with line features

    • D.

      Shapefile with point features

    Correct Answer
    D. Shapefile with point features
    Explanation
    The correct answer is "Shapefile with point features". This is because a network dataset requires linear features, such as lines or polylines, to represent the network connectivity and attributes. Point features, on the other hand, represent individual locations and do not have the necessary geometry or connectivity information to create a network dataset. Therefore, a shapefile with point features cannot be used to create a network dataset.

     Which of the following would be the best type of data layer to use to determine a best route in a system that included streets, subways and bus lines as options for travel?

    • A.

      Geodatabase with street feature class

    • B.

      Multimodal network dataset

    • C.

      Shapefile containing all transportation features

    • D.

      Street network shapefile

    Correct Answer
    B. Multimodal network dataset
    Explanation
    A multimodal network dataset would be the best type of data layer to use in this scenario because it allows for the integration of multiple transportation modes such as streets, subways, and bus lines. This dataset can accurately represent the connectivity and relationships between different modes of transportation, enabling the determination of the best route considering all available options. Other options like a geodatabase with a street feature class or a shapefile containing all transportation features may not have the necessary capabilities to handle multiple modes of transportation effectively.

     Which of the following would be the best example of the field equation used to calculate the travel time cost for each street segment in a street network?

    • A.

      [Length]

    • B.

      [Length] = Hours

    • C.

      [Length]/[Speed_Limit]

    • D.

      [Speed_Limit]

    Correct Answer
    C. [Length]/[Speed_Limit]
    Explanation
    The best example of the field equation used to calculate the travel time cost for each street segment in a street network would be [Length]/[Speed_Limit]. This equation takes into account the length of the street segment and divides it by the speed limit to calculate the travel time cost. This makes sense as the longer the street segment and the lower the speed limit, the higher the travel time cost would be.

    • B.

      Find Tool to locate and plot an address

    • C.

      Load Locations from an existing shapefile

    • D.

      Load Locations from an image of the geographic area of study

    Correct Answer
    D. Load Locations from an image of the geographic area of study
    Explanation
    Adding point data layers for network analysis typically involves adding specific coordinates or addresses. Loading locations from an existing shapefile, manually adding locations, and using the Find Tool to locate and plot an address are all valid options for adding point data layers. However, loading locations from an image of the geographic area of study does not provide the necessary coordinate or address information needed for network analysis, making it the incorrect option.

      Closed street

    • B.

      Dead-end street

    • C.

      One-way street

    • D.

      Streets with lower speed limits

    Correct Answer
    C. One-way street
    Explanation
    A one-way street is a restriction that could be used in network analysis. It limits the flow of traffic in only one direction, which can affect the overall network analysis and planning. This restriction can impact the efficiency of routes and the connectivity of different areas in the network. It is important to consider one-way streets in network analysis to accurately model and analyze traffic patterns and optimize transportation systems.

    • C.

      Determining the routes of ambulances to multiple incident locations

    • D.

      Determining the route for pizza deliveries by a delivery driver

    Correct Answer
    C. Determining the routes of ambulances to multiple incident locations
    Explanation
    Determining the routes of ambulances to multiple incident locations is not a good example of a scenario that could benefit from the Reorder Stops to Find Optimal Route option in network analysis because in emergency situations, the priority is to reach the incident location as quickly as possible rather than finding the optimal route. The urgency of the situation may require the ambulance to take the shortest or fastest route, regardless of the order of the stops.
