Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America and Article 10 of Regulation S-X under the Securities Exchange Act of 1934, as amended. The unaudited consolidated financial statements should be read in conjunction with our audited consolidated financial statements (and notes thereto) filed with the U.S. Securities and Exchange Commission (“SEC”) in our Annual Report on Form 10-K for the fiscal year ended October 31, 2013 (“Annual Report”). Unless otherwise noted, all references to years are to our fiscal year, which ends on October 31. In the opinion of our management, our unaudited consolidated financial statements and accompanying notes (the “Financial Statements”) include all normal recurring adjustments considered necessary by management to fairly state the financial position, results of operations, and cash flows for the interim periods presented. Interim results of operations are not necessarily indicative of the results for the full year. The accounting policies applied in the accompanying Financial Statements are the same as those applied in our audited consolidated financial statements as of and for the year ended October 31, 2013, which are described in our Annual Report. Effective in the first quarter of 2014, certain operations were transferred between certain of our reportable segments to better align business operations. Prior-period segment results have been restated to conform to these changes.
Parking Revenue Presentation	Parking Revenue Presentation One type of arrangement within our Parking business is a managed location arrangement, whereby we manage the parking lot for the owner in exchange for a management fee. For these arrangements, revenues and expenses are passed through by us to the parking lot owner under the terms and conditions of the management location contract. We report revenues and expenses, in equal amounts, for costs reimbursed from our managed parking lot clients.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In June 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2014-12 (“ASU 2014-12”), Compensation—Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period. ASU 2014-12 is intended to resolve diversity in current practice on how to account for the terms of share-based payments with performance targets that affect vesting and could be achieved after the requisite service period. Under the new guidance, these performance targets are considered to be performance conditions under Topic 718. As a result, the performance target is not reflected in the estimation of the grant date fair value of the awards. Compensation cost for such awards would be recognized over the requisite service period if it is probable that the performance condition will be achieved. ASU 2014-12 is effective for us beginning in our fiscal year ending October 31, 2016, and for interim periods within that year, with early adoption permitted. We will early adopt this guidance on a prospective basis in our first fiscal quarter of 2015. We do not expect that the implementation of this guidance will have a material impact on our consolidated financial statements. In May 2014, the FASB issued Accounting Standards Update No. 2014-09 (“ASU 2014-09”), Revenue from Contracts with Customers (Topic 606). ASU 2014-09 is intended to improve the financial reporting requirements for revenue from contracts with customers by providing a principles-based approach to the recognition of revenue. The core principle of the standard is when an entity transfers goods or services to customers it will recognize revenue in an amount that reflects the consideration the entity expects to be entitled to for those goods or services. The update outlines a five-step model and related application guidance, which replaces most existing revenue recognition guidance. ASU 2014-09 is effective for us in our fiscal year ending October 31, 2018, and for interim periods within that year. We are currently assessing the impact of implementing this guidance on our consolidated financial position, results of operations, and cash flows. In January 2014, the FASB issued Accounting Standards Update No. 2014-05 (“ASU 2014-05”), Service Concession Arrangements (Topic 853). ASU 2014-05 provides criteria for determining whether an arrangement qualifies as a service concession arrangement within the scope of the new guidance. Entities are prohibited from accounting for arrangements within the scope of ASU 2014-05 as leases. ASU 2014-05 is effective for us for our fiscal year ending October 31, 2016, and for interim periods within that year, on a modified retrospective basis to service concession arrangements that exist at the beginning of our 2016 fiscal year. We are currently assessing the impact of implementing this guidance on our consolidated financial position, results of operations, and cash flows. In January 2014, the FASB issued Accounting Standards Update No. 2014-01 (“ASU 2014-01”), Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects. ASU 2014-01 permits reporting entities to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. Under this method, which replaces the effective yield method, the cost of investment would be amortized in proportion to the tax credits and other benefits the reporting entity receives to income tax expense. Additionally, the guidance requires new disclosure for all investors in these projects. ASU 2014-01 will be effective for us for our fiscal year ending October 31, 2016, and for interim periods within that year, with retrospective application for each prior reporting period presented. We do not expect that the implementation of this guidance will have a material impact on our consolidated financial statements.

Disclosure of accounting policy for revenue recognition. If the entity has different policies for different types of revenue transactions, the policy for each material type of transaction is generally disclosed. If a sales transaction has multiple element arrangements (for example, delivery of multiple products, services or the rights to use assets) the disclosure may indicate the accounting policy for each unit of accounting as well as how units of accounting are determined and valued. The disclosure may encompass important judgment as to appropriateness of principles related to recognition of revenue. The disclosure also may indicate the entity's treatment of any unearned or deferred revenue that arises from the transaction.
