Keaukaha Collision Mitigation Study

Help us make Keaukaha safe for our cherished nēnē. Sign our petition urging Mayor Mitch Roth and the County of Hawaiʻi to take decisive action today!

Let's reduce collisions.

As nēnē populations increase and their range expands, they become exposed to more threats. In Keaukaha, we have observed sightings of 23 banded individuals and two goslings who utilize the stretch between Liliuokalani Park and Kings Landing, where at least four eight nene have died since 2021. Organizations such as ʻĀina Hoʻōla Initiative, Kamehameha Kumuola, and Hui Hoʻoleimaluō have restored areas along the coastline, which have attracted native species back to their natural range. It is crucial to develop infrastructure that allows better coexistence between native species and human activity.

*** While we typically refrain from disclosing nesting locations, we have made an exception to create this map, underscoring the significance of this area. Our intention is to emphasize the urgent necessity of implementing speed limit legislation and improving compliance with the speed limit

Can Technology mitigate these issues?

Maybe. But it requires data. We need a better understanding of how the community and visitors use this stretch of road.

  • Are the majority of drivers crossing over the center and shoulder lane divider to improve ride comfort?
  • What percentage of traffic is driving above the speed limit?
  • Does the introduction of new signage cause a noticeable change in behavior?

We plan to install custom-built speed logging devices and camera payloads along sections of this stretch of road to measure the impact of any speed mitigation measures, signage and/or increased enforcement. If any private property owners along Kalanianaʻole St. want to help support this initiative and keep this road safer please get in touch. 

Data Exploration

In May, our team has been engaged in the construction, testing, and deployment of custom-built radar speed data loggers along Kalaianaole St. The objective of this project is to gain a deeper understanding of driver behavior and speed compliance on this particular stretch of road. Initial analyses and visualizations of our recorded data seem to align well with our on-site observations, reinforcing the reliability of our data collection methods and the relevance of our findings. 

Radar was deployed within the school zone from 10:00am to 1:30pm.
Radar was deployed at 19.733744, -155.031257 from 10:00am to 2:00pm
Radar was deployed at Carlsmith Beach Park from 10:00am to 1:30pm.
Radar was deployed at Carlsmith Beach Park from 10:00am to 1:30pm. There was a mobile speed radar sign at Kumuola on 5/12/23 which likely explains the increase in vehicles traveling the speed limit.
