Urban road checkpoint and illegal parking capture system project in a certain district
Build a main road checkpoint capture, automatic evidence collection for illegal parking, detection and central control of pedestrians, and connect to the higher-level traffic management platform to uniformly forward data.

Project background
Eight key road sections in the main urban area have been affected by illegal parking and occupied lanes for a long time, and the traffic efficiency during the morning and evening peaks has been significantly suppressed. Due to the limited coverage of manual patrol law enforcement, the management department decided to build an automatic evidence collection system.
Construction organization
| Link | Arrangement |
|---|---|
| Road occupation approval | Submit for approval 15 days in advance, and the intersections will be divided into batches |
| Foundation pouring | Complete at night, cover with soil immediately after the curing period during the day |
| Grapple lifting | Operation after 22:30, set up reflective cones and full-time safety personnel |
| Online debugging | Conducted remotely during the day without affecting road traffic |
Performance
Within half a year after the system went online, the proportion of illegal parking on key road sections dropped by about 70%. The average traffic speed is increased by about 35%, while the pressure of manual patrols is significantly reduced.
Project difficulties
Issues that need to be addressed during project advancement
Construction requires road occupation, and night operation time is limited
Main roads cannot close lanes during the day
Existing poles at some intersections cannot bear load
Newly added equipment needs to be erected independently and undergo structural verification
Low recognition rate in strong light environment at night
Overexposure caused by oncoming car lights
Data needs to be uploaded to the superior platform in a standard format
The docking work involves the coordination of multiple vendors
solution
Technical and construction measures taken to address the above difficulties
Adopt phased night-time road occupation construction
Construction will be carried out every night from 22:30 to 05:30, and traffic warnings will be issued two days in advance
Added new members for stress verification
26 sets of new 8-meter monitoring poles for wind load verification
The bayonet uses a dedicated camera for license plates + stroboscopic fill light
The night recognition rate remains above 98%
Networking according to GB/T 28181 standard
Unify time and space benchmarks to avoid confusion in the bill of quantities at each intersection
Project results
Actual operating data after the system goes online
