如何在 ArcObjects 中通过 ReverseGeoCoding 查找多个交集结果？

我正在从事的项目要求我找到某个点附近的交叉路口（搜索街道中心线层）。对于 90% 以上的搜索，我似乎得到了适当的结果，但在某些情况下，我得到的交集在 ArcObjects 方面是技术上的交集，但达不到我需要的程度。

举个例子，如果我搜索距离 S. Main St 上某个点最近的交叉路口，我应该得到 S. Main St 和 S. Main St 的交叉路口。但是，该交叉点恰好是 N. Main St、S. Main St、W. First St 和 E. First St 的交叉点。因此，当我在搜索点上进行反向地理编码时交叉路口，我得到 N. Main St & 的单个结果S. Main St.

有没有办法让所有交叉路口都在同一点，而不仅仅是一个交叉路口？如果没有，有没有办法过滤可用的结果？

我当前的下面的代码最终得到的是 N.Main & 的值。 S.Main 在 junctionName 变量中。

ILocatorManager2 locMgr = new LocatorManagerClass();
ILocatorWorkspace locWorkspace = locMgr.GetLocatorWorkspace(this.wksp);

ILocator locator = locWorkspace.GetLocator("Streets_AddressLocator");

if (locator == null)
      return string.Empty;

IReverseGeocoding reverseGeo = locator as IReverseGeocoding;
IReverseGeocodingProperties reverseProps = reverseGeo as IReverseGeocodingProperties;
reverseProps.SearchDistance = 500;
reverseProps.SearchDistanceUnits = esriUnits.esriMeters;

IIntersectionGeocoding intersect = locator as IIntersectionGeocoding;

try
{
       IPropertySet propSet = reverseGeo.ReverseGeocode(pnt, true);
       intersectionName = propSet.GetProperty("Street").ToString();
}...

The project I'm working on requires me to find intersections near a point (searching a street centerline layer). For 90+% of my searches, I seem to be getting the appropriate results, however in certain instances I'm getting intersections that are technically intersections as far as ArcObjects is concerned, but not as far as what I need.

As an example, if I search for the intersection nearest to a certain point on S. Main St, I should get the intersection of S. Main St & First St. However, that intersection happens to be the intersection of N. Main St, S. Main St, W. First St and E. First St. As a result of this, when I do a reverse geocode on the point searching for intersections, I get a single result of N. Main St & S. Main St.

Is there any way to get all intersection at that same point rather than just one intersection? If not, is there a way to filter available results?

My current code below is what ends up with the value of N. Main & S. Main in the intersectionName variable.

ILocatorManager2 locMgr = new LocatorManagerClass();
ILocatorWorkspace locWorkspace = locMgr.GetLocatorWorkspace(this.wksp);

ILocator locator = locWorkspace.GetLocator("Streets_AddressLocator");

if (locator == null)
      return string.Empty;

IReverseGeocoding reverseGeo = locator as IReverseGeocoding;
IReverseGeocodingProperties reverseProps = reverseGeo as IReverseGeocodingProperties;
reverseProps.SearchDistance = 500;
reverseProps.SearchDistanceUnits = esriUnits.esriMeters;

IIntersectionGeocoding intersect = locator as IIntersectionGeocoding;

try
{
       IPropertySet propSet = reverseGeo.ReverseGeocode(pnt, true);
       intersectionName = propSet.GetProperty("Street").ToString();
}...
