Roadside monitoring

Roadside Monitoring — Each Mexico-domiciled motor carrier will be subject to intensified monitoring through frequent roadside inspections. 

Hydrants should be located on the street or roadside of all pipelines or drainage ditches to allow access for the pumper truck. Where large pipelines or drainage ditches may hinder access, access across such obstructions should be provided. Hydrants and manually operated monitors should be located outside of tank dike areas. Monitors capable of remote operation from outside tank dike areas may be located within that area.

An interesting study evaluated PMio exposure in 31 indoor shopkeepers and 33 outdoor roadside vendors in the Mongkok district of Hong Kong (Jones et al. 2008). PMio concentration was measured inside and outside air-conditioned shops using an aerosol monitor placed in the subject s working environment next to... 

Roadside safety performance will be closely monitored to ensure basic safety management controls are operating effectively. 

In addition, our safety department conducts random road checks of our drivers. We monitor roadside inspection reports in detail, customer paperwork, and occasionally ask for copies of gate logs where our units have been inside customer plants. 

NDIR are much used in the laboratory and in industry over short gas paths for gas concentration measurement. Recently, they have been applied to the longer paths required for stack gas monitoring and the much longer paths (hundreds of meters) required for ambient air monitoring. Measurements of gases such as methane, ethane, hydrochloric acid, carbon monoxide, and carbon dioxide have also been demonstrated at industrial sites and roadsides. 

If the data evaluation is fast enough then the recorded signal can be compared with a legal standard value in the case that it is surpassed, a camera is activated to capture the offending car s number plate (provided the speed of the car is not excessive). Such a situation is shown in Figure 28.10 for a TDLAS roadside sensor monitoring CO and CO2. 

Table 6.10 reports few levels of air lead higher than 0.20 pg/m, and the latter are for roadside air lead monitoring. The highest measurements were for Australian roadsides, in the range of 0.40— 1.00 pg/m (Al-Chalabi and Hawker, 1997). Hong Kong roadsides showed values 0.13—0.17 pg/m (Chan et al., 2000), with a value of 0.76 for an expressway between Jerusalem and Tel Aviv, Israel (Erel et al., 1997). Most reports recorded in Table 6.10 were for air lead levels around or below 0.10 pg/m. ... 

To determine if it is effective, the FMCSA will monitor the company s roadside inspections conducted by trained oflScers. If the company is receiving too many vehicle violations dm-ing roadside inspections, the company may be subjected to an audit. During the audit, the investigator will review the company s maintenance records, and will ask to inspect vehicles that the company has on-site that are considered as being in service. If the maintenance records are found to be inadequate, the company is not adhering to the maintenance schedules that have been established, or the vehicles are not in adequate condition, the company may be fined.

Automated road safety cameras use image capture technology to monitor and/or enforce traffic control laws, and to deter future illegal behaviours for example, to prevent speeding or running red traffic lights. The introduction of road safety cameras for enforcement purposes came about as a result of concerns that conventional enforcement mechanisms (e.g., police interception at the roadside) were not able to keep pace with increased traffic volumes and vehicle travel (Decina et al, 2007). 

The Safety Measurement System (SMS) quantifies the on-road safety performance of carriers and drivers to identify candidates for interventions, to determine the specific safety problems exhibited by a carrier or driver, and to monitor whether safety problems are improving or getting worse. SMS replaces SafeStat in the new operational model. The carrier SMS uses a motor carrier s data from roadside inspections, including all safety-based violations, state-reported crashes, and the... 

When the new enforcement model is up and running, it will enable FMCSA to monitor scores based on data that is updated monthly. This allows the agency to identify carriers that are having problem areas long before an on-site review of records takes place at the carrier s place of business. By intervening earlier, a carrier has an opportunity to fix deficient areas. CSA also allows FMCSA to suspend unfit carriers without a compliance review if data from roadside inspections indicates the situation warrants agency intervention. 

Monitor and track roadside inspection results to ensure that vehicle defects are repaired and documented promptly and to prevent OOS vehicles from operating prior to being repaired. 

Evaluate personnel who are monitoring vehicle maintenance performance by making sime they are using DVIRS, roadside inspections, and other data applying performance standards fairly, consistently, and equitably and docrunenting evaluations.
