Problem 5-16 The geometrics along a portion of roadway have been improved to provide wider travel lanes and paved shoulders. While these improvements have reduced the crash rate, the local traffic engineer is still concerned that too many crashes are occurring, particularly those involving collisions with fixed objects along the edge of pavement Thirty such crashes have occurred in the past 12 months. What countermeasure should the engineer undertake to reduce the number of crashes by at least five per year?

Solution

The counter measures that the engineer should undertake is as follows

Identifying the crash location: Inorder to identify the crash location we need crash data such as

Diagnosing the problem:

Diagnosis of the safety problems at a crash location is a four-step process

Selecting the Appropriate Countermeasures that match the problems identified:

As we found some possibilities which may cause crash now we need to select approprate counter measures to solve the above problems

Selecting the appropriate measures cannot alone reduce the fatal crashes but implementing them with proper monitoring can reduce the accidents. There are three important classifications or procedures to be followed for proper implementation and monitoring such as

Road saftey Impact Assesment

Road saftey Audit

Road saftey Inspections

Impact speed had the highest effect on fatality in fixed object crashes compared to all other variables. So strict rules must be imposed and the spped must be monitored by using cc cameras and thise who failed to follow the rules must be strictly punished.

complex layouts must be avoided while designing the roads even wider raods and paved shoulders are provided with complex layout it cant be helped to reduce the accident

Different boards showcasing different signs must be placed on the side of the road such that a driver can notice the curve of the road .

Edge of the road must be made evident to the driver by painting the edge of the roads with white strips such that a driver can notice what was the edge of the road that has provided.

Work with utility companies to relocate or eliminate utility poles of a history being to hit

improve work aone management safety practices

promote and implement corridor safety improvement projects

Other than being normal, any kind of physical condition of the driver increases the probability of being fatal in a crash so checkposts must be arranged inorder to check and find those vehicles
