For either a french drain, or a ditch, there must be some "away" for the water to go. The ground is saturated, it cannot absorb more, so the water will pond.
A french drain can be combined with a drywell, which can provide substantial dispersal and holding capacity, but that takes more space. It can also be connected to existing storm drain systems, but simply digging a trench or french drain will only provide so much extra capacity as dirt is removed.
When you're looking at houses, you're generally simply wanting to move water away from your house, and usually theres' yard space to move it too. I'm not sure how much the right of way extends beyond the trail, but it's a hill on both sides, there isn't a lot of room to store water. Certainly elements like these could have been included, for example, a well designed dry well under the trail probably would provide a lot of capacity to solve this problem, but I don't think it's an easy or cheap fix now.
On the other hand, raising the level of the asphalt by adding another layer would help by raising the level of the path above the water, not require storage for the water. It could still overflow the path, but it would take more water.
