An up-to-date report on the condition of every street in Corpus Christi should be ready for city planners by the end of January after a 60-day, street-by-street evaluation. In the past, the process to produce a similar inventory of street conditions would have taken three years, said a spokesperson for the city.
A two-person crew from Street Operations has been replaced by a van and a team from Transmap Corporation from Upper Arlington, Ohio. Transmap is a national provider of technical and management support services for the transportation industry. The company has been collecting roadway assets and pavement condition data in cities around the country for over 20 years.
The equipment used ranks each street’s pavement condition from 0 to 100, with 100 being the best. It also records signs, markings, signals, curbs, gutters and bridges, collecting a complete inventory of roadway assets.
The cameras and software capture ground-based, 360-degree, street-level images in HD. The van collects data as it drives over the streets, traveling a normal speed.
More than 1 million points per second are captured, along with panoramic images and conditions. Trained pavement technicians use the information to rate the type and severity of cracking and potholes on each street.
The entire project cost $372,000 and will be used by city planners, the council and the newly formed Ad Hoc Residential Street Infrastructure Advisory Committee. The committee of citizens expects to meet over a seven-month period to develop and evaluate a residential street reconstruction plan.
