The purpose of carrying out roads inspection is to ensure the safety and long term serviceability of all highway structures. In the UK the Highway Authority has maintenance responsibility to all roads all be it motorway and pedestrian footbridge. The purpose of inspection is to identify and report defects, which if ignored might lead to collapse, accident or high maintenance repair costs. Throughout the world road networks have been built rapidly over the last century. In some countries especially prosperous ones the rate of road building construction was far more vigorous than those countries with limited financial means. The usage of vehicles as means to travel and transport goods has been on the increase since the invention of the motorcar. Roads inspection is a vital activity to avoid incalculable cost to the national economy. Economical growth relies heavily on the free movement of people and goods, accordingly any failure in roads to serve its purpose will lead to economical retardation and ultimately recession. It can't be over emphasized that maintaining roads network in workable condition is vital

Highway roads play an important and vital role for the development of any country. They are the only way through which a country is interconnected. Perfect mapping of these highways in terms of quality and area covered lead to affluent development of country. People get themselves to their different destinations by these highways. The raw materials which are needed at distant manufacturing sites are provided by these highways. Exemplarily the United Kingdom highways are considered to be the perfect for road transportation of raw materials and public transportation.

Traffic congestion is the focus of every highway assignments. Round-the-clock congestion and complex traffic management issues are just some of the challenges which are to be faced with the modernization, planning and design and supervision. The following things are to be kept while building up efficient highways:

à Decresing the ambiguity and foster increase in durability.

à Maintaining the international road safety standards.

à Taking care of environment and surroundings.

à Timely Survey and reverting the sorted questionnaire of the citizens to the citizens.

United Kingdom is a world leader in transportation. They are world renown for record lowest casualties and road hazardous rates turning to fatality as compare to any other country, as well as for applying innovative technologies and methods for managing its infrastructure. UK having the networks of networks of roads that can be categorized in following ways: - The planned or road network at national standard is managed by the authorities of Highway roads and the non-planned, or locally, road networks are managed by state authorities. As they already have triggered the basic procedures and processes for resources by resource managing authority, it still has linchpin hurdles in retaliation, the conditions of the different road network. A recent trend in major road renovation plan was declared only in 2009, when appropriate affluent funding were allocated for the care for this part of the road networks. Till today, on local roads, over 4,000 bridges still need strengthening and 2,944 need major maintenance. From this about 31 percent of UK lighting columns are more than 35 years old, their expected life. The main sagaciousness for this set of affairs was showed up by the local governments, nearby 164 only are in UK main subcontinents itself, are responsible for a large portion of road network but the funds they receive from the national government ostensibly for sending and receiving tasks are then used in any government process, Given strong public pressures for quality transportations and social services and some of this funding is allocated to non-transportation activities, an rough calculation states that near by 11 percent of the affluent funding allotments for UK itself.

At the national level, the Highways Agency of the Department for Transport is responsible for UK major roads including about 17,754 kilometers (km) (14,818 miles (mi)) of major arterial roads, carrying 32 percent of UK's traffic volume and 55 percent of its heavy vehicle movements. One interesting aspect of the Highways Agency's road network is that, unlike other countries the team visited, the mileage for which the Highway Agency is responsible has decreased each year over the past decade, the agency has been turning roads and bridges back to local governments referred it as de-Trunking.

The strategic planning guidance for future years and beyond lists the following priorities for the road network: -

à Describing and proving the newest public traffic and role of management, including the progressive roll-out of traffic officers, regional control centers and supporting technology on the most congested parts of the motorway network,

à Maintenance and day by day increasing road safety constraints on the network to deliver the planned safety target and reaching the targeted goal of the no accident zone Roads policy.

à Maintenance and their road networks in a lot safer condition than the current condition while decreasing the whole danger to citizen's life costs. This helps avoid unplanned or more extensive and disruptive maintenance projects in future years.

Highway Inspections & Their Maintenance:

Road and bridges surveys are the necessity to identify deforms the need for routine and planned maintaining work and unlawful obstruction and the interference with the road and bridges and highway walls lengths. To assure a flawless whole country approach and implementing the system required of surveys, assessment methodologies implemented, analysed and action of road highway and bridge defects has been adopted. There are 4 types of road and bridges surveys taken out on perfect roads. These are:

à On predefined Inspections -It is carried out to identify roads and bridges and highway defects, obstruction and interference produced that are restrained to be a danger to road highways. Users are requiring paying attention to protect the road highways and bridges and keep the highway safe.

à Conditional Inspections- It is supposed to carry out for the pre-assessment of the present condition of the roads and bridges network and the need for planned roads and bridges maintenance by mongering authorities

à Specific targeted Inspections- They are undertaken following a particular request need or demand, where there are exceptional circumstances or in response to claims being made against the Highway Authority.

à Sudden Random Inspections- They are undertaken on an ad hoc basis.

Maintaining Bridges & Structures

On the public road network like in Yorkshire & Menchester, there are exactly:

à 1469 bridges and 358km wall length under the County Council

à 369 bridges and 89km of wall length under the private authority

The highways are basic component of the network connecting different routes and it is required that they are highly maintained and, if necessary foster. The highways must be entertain under the maintenance of the road, they carry and also to the overall management of the specified route. The yorkshire County Council operates under the private owners to assure that the designred plan also covers their highways and specified bridges.The authorities also have responsibilities of maintaining the pedestrains bridges on the Public Rights. These bridges are the most linchpin elementa of the Public Rights and authorities will have to work for maintaining and improvement of the network conditions.

Considerations:-

County Council, Yorkshire has a straight indulgement for the algorithms produced, as a expected amount of the algorithm is based on the stratagem and processes, principles and practice already follwed by the County Council in the management of such highway stuctures. The County Council is consequently early as this working too many of the principles laid down in the Code and will aim to adopt the full Code following its publication. This algorithm will subsist the authority to produced the effect in the favor of public in most optimized way as:

Controlling the Assets:-

This algorithm implemented in Practice recommends the use of an resource Managing framework for the management of highway roads and bridges based on an resource Management Plan, in way to deliver an ammend level of strategy and effective practices of managing and restrain. The County Council roads and bridged Managing Plans are produced as part of the Transport resource Managing strategies.

Preferred Inspections:-

The data provided in structural survey is basicity for the highway managing strategies, in order to denoument of the County Council commitments corporate objectives and survey of structures stock will continue to be undertaken in accordance with the Council current strategem to descriminate its status. The additional requirement of the algorithm implemented to pacify the Principal surveys will need few more resources and its adoption will be implemented according to the priority set by the higher authority, in order to denoument of the County Council commitments corporate objectives and survey of structures stock will continue to be undertaken in accordance with the Council current strategem to descriminate its status. The additional requirement of the algorithm inplemented to pacify the Principal surveys will need few more resources and its adoption will be implemented according to the priority set by the higher authority.

Indexing The Bridge Condition:-

The County Council is undertaking dual reporting of inspections and the results so far received have been used to produce a draft conversion to the SBIC. Yorkshire and Menchester Condition Indicators from 1995 to 2007 have been converted to the "SBIC" system.

Target Bridge Stock Condition Index:-

2007/08 Allocation for Structural Maintenance            " £8.809M" 

Required affluency on previous road structures developed    "£2.496M"

Required affluency on previous and new Railway tracks        "£2.255M"

Required affluency on Maintaining the Walls                         " £2.300M"

Estimated budget for work on Bridges                                      "£4.736M"

The County Council considers that this

In order to maintain the "SBIC" at the present marking of 91, is them assumed that a affluency status and also allocii for 2007/08 will be required for forwarding years. The implementation of a Value Management process is assumed to release funds from fostering work needs and can be put to renuvation works, around that a saving of £2.7 million for every year from starting of this strategy would initiate to locate the renuvation logs remained and on the same time lead to an in the SBIC from its current value of 91.

Figure above clearly represents that the breakless decreasing fashion in status showed up from 1993 and after that have hiatus in 2007/08 due to higher allottments between 2001/2002 & 2006/07. As stated that the impact of a minimum allottments made in 2006/07, have to be cogent cause of the time period differs in affluency & survey.

The Scheme Prioritisation: -

Previously, the fostering of the standard roads and overfly was the main needs in the algorithm stated, as a consequence Other roads and bridge renuvations was only proceed out where it was supposed that the plan was required to the stagnation of the bridges and the safety of the public using it. Previously, the fostering of the standard roads and overfly was the main needs in the algorithm stated, as a consequence Other roads and bridge renuvations was only proceed out where it was supposed that the plan was required to the stagnation of the bridges and the safety of the public using it This would ensure that structures do not deteriorate to the extent where preventative maintenance is no longer possible, obviating the need for essential maintenance works and thus preventing an escalation in maintenance costs. The additional requirement of the algorithm implemented to pacify the Principal surveys will need few more resources and its adoption will be implemented according to the priority set by the higher authority, in order to denoument of the County Council commitments corporate objectives and survey of structures stock will continue to be undertaken in accordance with the Council current strategem to descriminate its status. The additional requirement of the algorithm inplemented to pacify the Principal surveys will need few more resources and its adoption will be implemented according to the priority set by the higher authority.

Final Assessment of The Structures:-

Assessment of structures is part of the resource Managening authority and surfiets regarding information about the weight carrying capacity of the roads and bridges and their inability and ability to meet present and near by future performance needs it also includes the detoriation caused. The 50 tonnes consignment process for bridges stated in the previous scenario are substantially complete. The planned consignment of keeping walls has commenced and requirements of the ongoing practice of ad-hoc consignment of keeping walls that signals the distress status. At one time consignments of all roads and bridges have been completed, then the County Council will introduce a priority based process to undertake and fosters 'steady state' consignments for roads and bridges and followed with the algorithm in Practice implemented, when conditions or events occur that increase imposed loads or decrease the weight handling capability of the roads and structures.

Strengthening and Other Permanent Measures:-

Previously, the priority setup was given to the strengthening of standard bridges. As the work necessary to bring the standard bridges and retaining walls up to full strength must have been added to the roads and bridges workbank and value managed along all other respectve requirements. As a result of that unexpected ammendment in the priortised fostering work, it may be necessary to negotiate and reconsider in making interim measures permanent as an alternative to permanent fostering.

Asset Protection:-

The County Council has several processes in place to preserve the bridged and maintain the clear operating steps of the publical highways in collaboration with other private parties. As the work necessary to bring the standard bridges and retaining walls up to full strength must have been added to the roads and bridges workbank and value managed along all other respectve requirements. As a result of that unexpected ammendment in the priortised fostering work, it may be necessary to negotiate and reconsider in making interim measures permanent as an alternative to permanent fostering..

Accesing and Managing the Performance Manifestation:-

The County Council proposes to continue to report on the numbers of outstanding bridge strengthenings and retaining wall assessments and retaining wall rigidness in collaboration with members of the "Yorkshire and Menchester bridge conference" by authority.
