Road Safety Engineering
Government of Kerala has initiated various programmes to address the alarming issue of increasing road accidents by coordinating all stakeholders of Road safety viz., Engineering, Education and Enforcement agencies.
Public Works Department is primarily responsible for Engineering aspects and a safety engineering component has been introduced as a part of world bank aided Kerala State Transport project.
Initiatives in PWD
- Constitution of Road Safety Unit
A road safety unit has been constituted under the Chief Engineer (R&B and IT) supported by an Executive Engineer, 2 Assistant Executive Engineers and 2 Assistant Engineers
- Road safety Engineering Tool kit
A comprehensive road safety tool kit has been developed for accident prevention and accident reduction as follows:
- Road safety engineering manual
- Accident site improvement manual
- Road safety audit manual
- Road safety notes
- Roundabout design
- Crash barrier
- Speed survey
- Road signs
- Supplementary Technical advice for IRC 67
- Sign fonts
- Technical specification
- Technical specification for safety related items
- Checklist for procurement of traffic signs

| Road safety Audit- Model Road
The section of road between Thiruvananthapuram and Kollam of NH-47 has been selected as Model road to demonstrate as model road with regard to Road safety, coordinating all stakeholders of Road safety. The Road safety cell undertook a Safety Audit for the road and bids are now under tendering stage.
Salient Features
- Complete Signs and Markings to demonstrate and enforce under Road safety Action Plan
- No overtaking centreline based on visibility check
- Roundabouts, junction with Traffic Signal and priority junction for demonstration
- School Zone treatment
- Pedestrian crossing treatment
- Highly visible studs and markings
- Crash barrier for deep drops
- Delineators to guide drivers at night
- Curve treatment with Chevrons

Mass Action Scheme |
| Demonstration signs and markings
In order to demonstrate ideal signs and markings according the IRC and International practises two Demonstrations schemes have been implemented on NH – 47 with a view to achieve consistency and uniformity.
- Signs and Markings at Kazhakuttam junction at the take off point of Trivandrum bypass on NH- 47
- Signings at Ambalapuzha – Haripad section of NH- 47

Junction Improvement Schemes
The road safety cell is now engaged in design of junctions giving attention on safety engineering measures.
- Design completed for 8 junctions in Pathanamthitta ring road
- Survey and design is progressing for 10 junctions in Tiruvalla town
Mass Action Schemes
The median end of various reach of NH – 47 are being hit by vehicles especially night. In order to counteract such accident, similar treatment by way of diagonal markings reinforced with Rumble strip and studs and signs have been installed for all median ends between Trivandrum and Cherthala on NH - 47.
Safety Improvement of Hazardous locations of NH
As considerable number accidents are occurring on National Highway, at the request of State level monitoring committee, Road safety cell carried out site visit and proposed countermeasures to 74 hazardous locations on NH –47 and 42 hazardous locations on NH –17. The work has been awarded.
Safety Assessment of RMC roads
The road safety cell carried out safety assessment of KSTP's maintenance roads and implemented required safety engineering measures in order to counteract the accident due to better riding quality. Measures have been implemented for 600 km road through out the state and balance for 350 km is underway.
Road Accident Database
The PWD in association with Police Department has developed GIS-enabled accident database called GeoKAMS. It has following features.
- Automatic generation of collision diagram with vehicular movements
- Advanced querying and reporting
- Many new advanced features like:
- High accident location identification
- Scenario Analysis
- Spot / Intersection Analysis
- Cluster Analysis
- Strip / Corridor Analysis
- Ability to add Accident photograph or location photograph along with the accident data.
